    Taiwan is a representative region of the land reclamation and the intensive human-environment interaction. The study on the reconstruction of the spatial and temporal change of historical farmland in this province can deepen the understanding of the characteristics, differences and rules of the historical land change process on both Taiwan and the mainland. Based on historical literature and statistical yearbooks, this study uses population data to analyze the characteristics of farmland and population records. Then it comprehensively adopts methods such as citation substitution, linear interpolation, occult coefficient correction method and per capita farmland coefficient method to estimate and correct the spatial and temporal changes of historical farmland in Taiwan province in the past 300 years after verifying the surplus food quantity. The results are shown as follows: (1) The total amount of farmland in Taiwan increased from 0.91×104 hm2 in the Dutch occupation period to the current 79.30×104 hm2, up nearly 86.60 times. The stage characteristics generally increased first and then continued to decrease. In the middle and early periods of the Qing Dynasty, it showed steady and low-speed growth. During the Japanese occupation period, it showed rapid fluctuations. Then it experienced a slow fluctuation in the middle and early periods of the Republic of China, and gradually declined in the middle and late periods of the Republic of China. (2) On a 100-year scale, there are significant differences in the rules of change between paddy fields and dry fields in Taiwan; the amount of paddy fields increased first and then gradually decreased after volatility. However, the dry farmland increased first and then decreased and then gradually increased. Before 1931, the proportion of dry farmland was higher than that of paddy fields, and its peak period witnessed 3% to 5% higher; then the proportion of paddy fields exceeded that of dry farmland and was in an advantageous position. The average proportion of paddy fields from 1936 to 1965 was 22.23% higher than that of dry fields. (3) The land reclamation process in Taiwan has represented the imbalance between spatial expansion and regional expansion. Land reclamation experienced the development process from one region to the whole area of Taiwan Island, that is, from the south to the north, and from the west to the east. Tainan was the first region to be reclaimed, followed by Taichung and Taipei districts, and the Taitung region was the last one to be reclaimed. The reclamation intensity in Tainan was higher than that in the rest, with a maximum of 36.71%. (4) The HYDE dataset and the results of this study are gradually increasing, but the difference between the farmland area and the change process is significant. The international dataset does not reflect the objective historical facts of the change of farmland in Taiwan in the past 300 years.

    HUANG Xian-jin, ZHANG Xiu-ying, LU Xue-he, WANG Pei-yu, QIN Jia-yao, JIANG Yun-chen, LIU Ze-miao, WANG Zhen, ZHU A-xing
    JOURNAL OF NATURAL RESOURCES    2021, 36 (12): 2995-3006.   DOI: 10.31497/zrzyxb.20211201
    Abstract1294)   HTML404)    PDF (3793KB)(270)      

    This study explores the possibility of carbon neutralization in China before 2060, based on the predicated carbon emissions from human activities and the carbon sinks produced by the territory ecosystem. The results show that the total anthropogenic carbon emissions in China is 0.86 Pg C yr -1 in 2060, and the ecosystem would neutralize 33% and 38% of the anthropogenic CO2 emissions in 2060 under the scenarios of IPCC RCP 2.6 and RCP 6.0. In 2060, woodland, grassland and cultivated land will be the main contributors of carbon sink, accounting for 93% of the total carbon sink. Compared with the year 2030, the contribution of carbon sink from woodland and grassland will decrease by 10% and 8%, respectively under RCP 2.6 scenario, while the contribution from cultivated land will increase by 18%; the contribution of carbon sink from woodland and grassland will decrease by 7% and 2%, respectively under RCP 6.0 scenario, while the contribution from cultivated land will increase by 4%. However, based on the highest carbon sink (2055) during 2051-2060, 65% and 82% of anthropogenic carbon emissions would be neutralized respectively. Therefore, to achieve carbon neutrality in 2060, the varieties of the bearing capacities of carbon budgets from different land use types should be fully considered in the territory planning.

    SHEN Jia-shu, LI Shuang-cheng, LIANG Ze, WANG Yue-yao, SUN Fu-yue
    JOURNAL OF NATURAL RESOURCES    2021, 36 (8): 1909-1922.   DOI: 10.31497/zrzyxb.20210801
    Abstract962)   HTML384)    PDF (2361KB)(221)      

    Understanding the relationships between ecosystem services supplies and demands is of vital importance for sustainably utilizing natural capital and coordinating ecosystem services supplies and demands. According to the previous research on ecosystem services at home and abroad, the research framework of the relationships among ecosystem services supplies and demands was put forward in this study. Within this framework, the formation mechanisms and representations of the relationships between ecosystem services supplies and demands were explained, the basic characteristics of the relationships between ecosystem services supplies and demands were summarized, and the potential research focuses were proposed, which could provide a guidance for the studies on the ecosystem services and the governance of ecosystem services. In general, there were two non-exclusive mechanisms that formed the relationships between ecosystem services supplies and demands. On the basis of these formation mechanisms, the representations of the relationships between ecosystem services supplies and demands included bundles, trade-offs, synergies and no-effect relationships. In terms of the characteristics, the relationships between ecosystem services supplies and demands could be spatially heterogeneous, temporally variable and scale dependent. The construction and evaluation of indexes, statistical analysis of indicators, development and simulation of scenarios, and spatial mappings and analysis were the four main methods to study the relationships between ecosystem services supplies and demands.

    LIU Jie, TANG Rong, LI Ping
    JOURNAL OF NATURAL RESOURCES    2022, 37 (1): 83-95.   DOI: 10.31497/zrzyxb.20220106
    Abstract955)   HTML226)    PDF (2724KB)(80)      

    With unique tourism resources, the Antarctic attracts more and more attention, and the number of tourists to the region is growing rapidly. However, there have been fewer studies on the Antarctic tourism resources, and the research on the classification and evaluation of its tourism resources is almost blank. In this paper, the classification and spatial distribution of the Antarctic tourist resources are studied, and suggestions for the development of Antarctic tourism are put forward, in order to provide a reference for evaluating, developing and conserving these tourism resources. Results show that: (1) In the Antarctic region, substantive tourist activities have been carried out in 558 major tourist resource units, which can be divided into 8 main types, 18 sub-types and 30 basic types according to different attributes. (2) There are diversified natural tourism resources, among which water landscape occupies a large proportion. (3) The tourism resources are unevenly distributed and typically characterized by aggregated distribution, and two high-density clusters are formed in the Antarctic. One is the coastal areas of Graham Land in the northwest of the Antarctic Peninsula and their surrounding islands, and the other is the islands and continent areas near the Ross Sea. (4) Climatic condition and the accessibility of tourism resources are important factors affecting the spatial distribution of Antarctic tourism resources. (5) There are less Antarctic tourism resources related to China, and China's participation and maturity in the development of Antarctic tourism are relatively low. In the future, China should find out the status of Antarctic tourism resources as soon as possible, strengthen the research on the impact of Antarctic tourism, and promote the development of China's tourism to the Antarctic.

    Abstract905)   HTML327)    PDF (1005KB)(138)      

    The construction of ecological civilization is an important national strategy in China, and the Qinling Mountains play a strategic position in the construction of ecological civilization in China. To clearly understand the existing problems and paths of ecological civilization construction in the Qinling-Daba Mountains, nine well-known researchers from different fields were invited in an interview on cutting-edge research topics in the Qinling Mountains. The interview covered such topics as ecological patterns and geographic processes, scientific investigations, rural revitalization, and water resources protection. The results of the interview show that: to gain a better understanding of the important value of the study area and to carry out the ecological protection and sustainable development in the New Era, it is necessary to understand the ecological and environmental effects of the North-South Transitional Zone of China, reveal the ecosystem service functions, emphasize the pivotal role in maintaining national ecological security, and conduct research on ecological protection and restoration of the Qinling Mountains. It is significant to continuously monitor the ecological functions, build an intelligent monitoring system integrating "Space-Air-Ground", continue to carry out comprehensive scientific investigations, pay attention to major scientific propositions, discover the unique geographical phenomena and laws of the Qinling Mountains, and form a scientific data sharing mechanism and platform to support regional scientific research and decision support. Under the new mobility paradigm, we should look at the resettlement project from a dynamic perspective, focus on the livelihoods of different groups and types of immigrants, and solve immigration problems through a diversified security system. In the context of climate change, it is necessary to attach importance to the response of the Qinling Mountains to climate change and human activities, strengthen the construction of regional transportation infrastructure, find out the law of evolution and changing trend of Qinling Mountains' water resources, and to carry out systematic management to ensure long-term and safe supply of water resources, and promote sustainable social and economic development.

    SONG Ma-lin, CUI Lian-biao, ZHOU Yuan-xiang
    JOURNAL OF NATURAL RESOURCES    2022, 37 (1): 1-16.   DOI: 10.31497/zrzyxb.20220101
    Abstract898)   HTML376)    PDF (1244KB)(154)      

    Natural resources play an important role in a country's development. Since the 19th National Congress of the Communist Party of China (CPC) in 2017, China has attached great importance to the management of natural resources. China's natural resource management systems, institutions, concepts and methods have been constantly reformed and innovated, and management systems and models that are more suitable to China's national conditions have been gradually formed, with remarkable results. However, there are still many inadequacies and contradictions in management practice. Starting from current situations of China's natural resources management system and institutional construction, this paper expounds the difficulties in developing natural resources management system and institutional construction from three aspects: management object, management subject, and management guarantee; summarizes prominent practical problems that restrict the development of management practice at present; and finally provides thinking and suggestions for China's natural resource management system reform and institutional construction in the future from two aspects: constructing the multi-dimensional natural resource management system and perfecting the natural resource management system under the perspective of national security. This will help further promote China's sustainable development and ecological civilization construction in the future.

    Abstract718)   HTML223)    PDF (4962KB)(140)      

    This paper summarizes the research process of rural tourism in China through systematic literature review, which contains three stages: primary application research (1992-2005), diversified expansion research (2006-2015), and integration deepening research (2016-), as well as analyzes the background and research value orientation of each stage. Based on the analysis of knowledge map by CiteSpace, it reveals the changing process and characteristics of research topics. Combining the rural revitalization strategy and tourism development needs in the New Era, the research expounds the basic characteristics of rural tourism, constructs the research framework of rural tourism in the New Era, puts forward the main scientific issues, and proposes the research trends and academic innovations of rural tourism research. Moreover, the research emphasizes that rurality and recreation constitute the fundamental characteristics of rural tourism. Future research should focus on the national strategy and high-quality development requirements of the New Era, as well as keeping up with the international academic frontiers. Meanwhile, based on the local practice of rural tourism research in China, relevant research should concentrate on the "five-sphere integrated plan" basic framework for rural tourism, taking industry, ecology, culture, governance, and livelihood as the core elements. Under this research framework, it is essential to focus on the rural area system with its complexity and key tourism scientific issues, to strengthen research platforms and professional talents, to integrate multidisciplinary theories and technology methods, as well as to reinforce the ideas of data-driven and science-technology energization. It is also necessary to reveal the process, patten, mechanism, and rule of rural revitalization pushed by rural tourism in a deep-going way, to explore the development model and path of rural tourism revitalization with distinct Chinese characteristics, to continuously promote the deepening of theoretical research, practical application innovation and the development of rural tourism discipline, besides, to improve the academic research, innovation ability, service value, and internalization level of rural tourism.

    Red scarf children's cognition of red tourism resources and patriotism: Evidence from Yuhuatai Revolutionary Martyrs Memorial Area in Nanjing
    ZHONG Shi-en, LU Wen-bin, PENG Hong-song, DAI Shu-qi
    JOURNAL OF NATURAL RESOURCES    2021, 36 (7): 1684-1699.   DOI: 10.31497/zrzyxb.20210705
    Abstract716)   HTML158)    PDF (1173KB)(54)      

    This study illustrates how China uses red tourism to strengthen patriotic education among its children. Taking the Yuhuatai Revolutionary Martyrs Memorial Area in Nanjing (hereinafter referred to as Yuhuatai) as the research case, this study integrates multiple methods, including structured Motherese interview to allow children to speak for themselves, unstructured in-depth interviews, field survey, and second-hand data collection, etc., to interpret whether there is likely another reality in the children's understandings of red tourism resources and patriotism. This study aims to demonstrate why and how patriotic education should start from childhood. The results illustrate that: (1) In children's eyes, compared with other types of tourism activities, red tourism is equivalent to patriotic tourism, with special significances given to visiting solemn places and to commemorating revolutionary martyrs. The particularity of red tourism is also reflected in the on-site activities and ceremonies. In children's eyes, Yuhuatai is not a play place for fun and freedom, but a beautiful landscape space, a real and sacred historical space, and a learning space of spirits. "Sacred, solemn, and beautiful" are the three recurring concepts that the children most used to describe Yuhuatai. They thought Yuhuatai has great significance for their learning and growth. Yuhuatai is a sacred space to clarify the meaning of the red scarf and the mission of CYP (China Young Pioneers) members. Obviously, red tourism has become an affectionate tie to China and the Chinese people, as well as among Chinese children. (2) In general, they treat patriotism as a lofty ideal, and the pureness of their patriotism reflects that patriotism can be evoked and learned deeply through tourism practices, especially at the beginning stage of life. In children's eyes, patriotism is a compound of bearing in mind of the martyrs' spirit, shaping national identity, and inheriting the martyrs' spirit. Patriotism can be started with small and simple daily things. They can practice patriotism and do their best through the following means, such as, studying harder, loving life, protecting the environment, and respecting the elderly. In recent years, Yuhuatai has launched a variety of means to promote patriotic education among children, including childlike narration around several martyrs' learning and growth stories for children visitors, recruitment of children narrators to exercise their comprehensive abilities and to incorporate them to participate in the publicity of "red heritage faith", colorful summer camp activities to promote patriotic education in the name of edutainment, co-construction of ideological and political curriculum with primary and secondary schools in Nanjing, and ceremonial education around specific occasions. The practice of Yuhuatai has important enlightenment for how to innovate the ways of promoting patriotic education among children for red tourist areas, especially for museums and memorial halls.

    The impact of red tourism on national identity of tourists
    LIU Run-jia, HUANG Zhen-fang, YU Run-zhe, BAO Jia-qi, MO Yu-ting
    JOURNAL OF NATURAL RESOURCES    2021, 36 (7): 1673-1683.   DOI: 10.31497/zrzyxb.20210704
    Abstract699)   HTML172)    PDF (794KB)(103)      

    Red tourism is an effective carrier in inheriting red gene, strengthening patriotism education and enhancing national identity, however, there have been few studies on its political function. Based on the theory of cognitive evaluation emotion evaluation and positive emotion expansion construction theory, this paper constructs the impact model of red tourism national identity and puts forward the corresponding hypotheses. The PLS SEM is used to test the structure equation. The results show that the model has good explanatory and predictive power, and the model is featured by cross validity. The GOF value of the overall model is higher than the standard value of good fitness; red tourism has positive effect on national identity of tourists. As the intermediary variable in the process of red tourism, red tourism emotion is connected with tourist experience and identity. The influence of historical identity on national identity is not obvious, so it is necessary to further arouse historical memory and enhance the function of historical education in red tourism. The research results can provide theoretical basis for strengthening the research on the national identity of red tourism, expanding the theoretical connotation and educational function of red tourism and promoting the high-quality development of red tourism.

    Research progress and key issues of territory consolidation under the target of rural revitalization
    HAN Bo, JIN Xiao-bin, GU Zheng-ming, YIN Yan-xing, LIU Jing-ping, ZHOU Yin-kang
    JOURNAL OF NATURAL RESOURCES    2021, 36 (12): 3007-3030.   DOI: 10.31497/zrzyxb.20211202
    Abstract692)   HTML233)    PDF (4437KB)(196)      

    After nearly 40 years of development, China's territory consolidation has played an important role in promoting rural farmland protection, solving the problem of inefficient use of land resources, and helping poverty alleviation. This article reviews the development process of China's territory consolidation, summarizes relevant research progress based on bibliometric analysis and literature reviews, and puts forward key issues for future territory consolidation research. The following conclusions are drawn: China's territory consolidation undertakings and research have gone through three stages including territory consolidation planning, special territory consolidation projects, and comprehensive territory consolidation. The promotion of rural revitalization is the most important historical task of current territory consolidation. At present, territory consolidation research has formed a distinctive research system with the goal of solving the problem of land space and resource utilization and guided by policy management needs. Land use research is the theoretical support of territory consolidation, with agricultural land consolidation, rural settlement consolidation, comprehensive land consolidation and land-space ecological restoration as the main objects. Territory consolidation research formed a decentralized group consisting of management departments and characteristic scientific research institutes as the core research bodies. The territory consolidation research under the rural revitalization goal focuses on land consolidation planning, project site selection, consolidation zoning decision-making, land consolidation project full-process monitoring and supervision and performance evaluation, rural settlement consolidation potential evaluation, land consolidation policy effectiveness evaluation and other management needs. Besides, much research has been carried out on scientific issues such as the mechanism of land consolidation driving ecosystem change, the optimal allocation method of land resources, and the coordination mechanism of land use conflicts, giving full play to the characteristics of geography for theory serving practice. To accelerate comprehensive land consolidation in the future, we should focus on solving key issues around "theoretical framework-problem identification-planning and decision-technical system", and use theoretical research to promote the development of China's territory consolidation, and contribute to the realization of rural revitalization.

    A better understanding of the connotation of "territory" is a prerequisite for developing the theoretical system and advancing the practical work of spatial planning. It is necessary to constantly update the understanding of "territory" in accordance with the development of disciplines and the changes in the real needs of spatial governance. Therefore, this journal invited 15 young scholars to discuss the connotation of "territory". The main points of view are as follows: (1) Territory is a complex coupled human and natural systems, with the characteristics of pluralism on elements and nesting on spatial and temporal scales. It is necessary to use the thinking of "landscape, forest, field, lake and grass" as a life community to carry out the comprehensive development and utilization and systematic restoration and protection of territory, so that it can become a natural governance platform. (2) Territory is a network space constructed by "flow" and a relational space composed of different stakeholders. It is necessary to integrate the territory through the "space of flows" to promote the sharing of resources and elements between regions to achieve coordinated development; it is also necessary to pay attention to the reconstruction of human and natural relationships and interpersonal relationships, coordinate the interests of multiple subjects, and achieve harmonious development. (3) Territory is a human space. It is necessary to fully perceive the risks, suitability, constraints, and accessibility of the territory. We need compile people-oriented spatial planning to enhance the ecological value, aesthetic value and humanistic care of territory. (4) Territory is the object of spatial planning and governance. It is a specific spatial carrier with marine space, rural space and cultural space, etc. It has attributes such as rights and assets. It is necessary to realize the unified management of resources and assets in the spatial planning, and highlight its economic value, social value and ecological value to achieve the diversified needs of high-quality development and high-quality life for territory.

    Rural living environment improvement and rural revitalization
    LI Yu-rui, CAO Li-zhe, WANG Peng-yan, CHANG Gui-jiang
    JOURNAL OF NATURAL RESOURCES    2022, 37 (1): 96-109.   DOI: 10.31497/zrzyxb.20220107
    Abstract659)   HTML180)    PDF (1109KB)(104)      

    Since the 21st century, China's rural social and economic development and infrastructure construction have attained remarkable achievements, but the imbalance between urban and rural development and inadequate rural development are still prominent. In particular, the living environment closely related to rural life is still the short board of rural development. At the beginning of 2018, the central government issued the three-year action plan for rural living environment improvement (RLEI) to focus on improving the rural living environment, building a beautiful and livable village, and pursuing the Rural Revitalization Strategy. This paper analyzes the concept and connotation of RLEI, explains the mechanism of RLEI promoting rural revitalization, combs the mode and mechanism, effect and evaluation of RLEI, and discusses the key areas of strengthening the research of RLEI. The science of rural living environment has developed rapidly in the past 10 years, and has made remarkable progress in basic theory, evolution mechanism, quality evaluation, regulation and control strategy, especially in the research of basic theory, evolution mechanism and quality evaluation. However, there are still obvious deficiencies in the guidance and support of the current research for practice, and there are still some misunderstandings in the practice of local specific RLEI. Facing the strategic needs of rural revitalization, we need to form "eight consensus" in the understanding and practice of RLEI in the new era. In terms of research, we should strengthen the intersection and integration of rural geography and engineering technology science, urban and rural planning science, management science, sociology, etc., and strive to form a systematic research system integrating theoretical research, technological development, mechanism analysis, effectiveness evaluation, and model optimization, which can better support the improvement of rural living environment and realize the function and value enhancement of rural areas, and then effectively contribute to the Rural Revitalization Strategy.

    The development of Chinese urban green finance and its influencing factors: An empirical analysis based on green bond
    ZHU Xiang-dong, ZHOU Xin-yi, ZHU Sheng-jun, HUANG Hai-feng
    JOURNAL OF NATURAL RESOURCES    2021, 36 (12): 3247-3260.   DOI: 10.31497/zrzyxb.20211217
    Abstract616)   HTML186)    PDF (2016KB)(45)      

    Green finance, which aims to regulate social capital flows, optimize the industrial structure, and realize green growth, has been a promising area of financial innovation. Since 2015, both the Chinese central and local governments have issued various policy incentives to benefit green finance. As a result, many cities in China have introduced and practiced green finance, which led to a boom. Previous research focuses on the concept and development of green finance, enterprises' and financial institutions' performance, but largely neglecting its regional disparity and influencing factors. This paper takes green bonds issued from 2016 to 2019 in 142 Chinese prefecture-level cities as a case. Based on the panel data model and spatial Durbin model, we explore the influence of policy incentives, financial development, and environmental pollution on the green bond issuance scale in different regions. Meanwhile, the interaction between variables has been explored to reveal the regional heterogeneity of green finance development. The results reveal that green bonds are mainly distributed in cities with a robust financial basement and a high administrative level. Although quite a few cities in the central and western regions started to issue green bonds after 2015, the growth of green bonds mainly took place in the eastern region. Policy incentives and financial development have significantly promoted the growth of green bonds, while environmental pollution has impeded the issuance. Policy incentives provide a low-risk context and stimulate the local financial sectors to innovate in green finance across China. However, the obstacle brought by environmental pollution can only be alleviated by the policy in the eastern region. Environmental pollution, generally caused by polluting industries, is a challenge for the central and western regions to develop green finance. With applicable policy incentives and robust financial industries, the eastern region can easily follow the green economic transformation trend and realize green finance innovation. For the central and western regions, the conflict between economic and environmental goals impeded the development of green finance. This paper suggests that more attention should be paid to regions with weak financial foundations and severe pollution. A regional cooperation platform should be established to improve the inclusion of green finance.

    LIANG Xin-yuan, JIN Xiao-bin, SUN Rui, ZHANG Xiao-lin, LI Han-bing, ZHOU Yin-kang
    JOURNAL OF NATURAL RESOURCES    2021, 36 (12): 3031-3053.   DOI: 10.31497/zrzyxb.20211203
    Abstract608)   HTML205)    PDF (2356KB)(175)      

    The optimal allocation of land resources is an important means to improve land use efficiency, alleviate land use conflicts, and promote harmonious man-land development. Current research on the optimal allocation of land resources in China has made great progress in theoretical exploration and practical applications. However, in the face of rapid land use changes, inefficient land management, and ecosystem degradation, the traditional optimal allocation way based on "quantity-spatial coupling" has been unable to meet the current needs in pursuit of a better life and sustainable development goals. Meanwhile, global food security is facing a series of severe challenges. The optimal allocation of land resources will directly affect and act on the coordination process between food production and economic development conflicts. Since the reform and opening up in the late 1970s, to serve the national strategic needs and key areas development (Yangtze River Delta and coastal areas), Nanjing University has carried out much research and practice around land resources optimization, so as to achieve the goal of ensuring resource security and food security. Researchers have focused on farmland pattern optimization, farmland intensification transition, farmland protection and planning, land use and urban-rural planning, land consolidation and agricultural land management, land use system innovation, land economic policy optimization and other characteristic research fields. Research directions take advantages of interdisciplinary deveoplment of geography and management, and have made contributions to disciplinary development and institutional innovations in the optimization and sustainable use of national land resources. In brief, this paper summarizes the key issues on China's land resource allocation by systematically combing the research progress related to the optimization allocation of land resources. Furthermore, on the basis of reviewing the academic contributions of Nanjing University, the opportunities and challenges faced by the optimal allocation of land and resources in China from the perspective of food security are summarized. The research can provide references for sustainable land use optimization.

    Resource and environmental carrying capacity in China for 35 years: Evolution, hotspots, future trend
    SUN Yang, WANG Jia-wei, WU Shi-dai
    JOURNAL OF NATURAL RESOURCES    2022, 37 (1): 34-58.   DOI: 10.31497/zrzyxb.20220103
    Abstract581)   HTML226)    PDF (3714KB)(166)      

    Based on statistical core journals and core scholars, this paper uses softwares such as CITESPACE, ORIGN, and Data-Driven Documents, to review the development of research, sort out hotspots and put forward research prospects on resource and environmental carrying capacity (RECC) assessment in China in the past 35 years. The results show that: (1) The evaluation of RECC in China follows the trajectory of "single factor", "multi-factor" and "dynamic integration", and the applied research evolved from "population capacity", "unilateral problem of regional development (RD)", to "multifaceted problem of RD". (2) According to the logic of "scientific evaluation - mechanism disclosure - practical application", this paper points out that, scholars mainly used the index system method, comprehensive evaluation method, footprint method and other methods to estimate the bearing capacity. Based on the calculation results, scholars summarized the spatial and temporal distribution of carrying capacity, identified the impact factors, and revealed the mechanism, to play a supporting role of carrying capacity in promoting regional economic development, speeding up new urbanization, optimizing territorial space, monitoring, early warning, simulation and prediction. (3) Based on the above, it is suggested that the following four aspects should be further optimized, namely, interdisciplinary research, specificity and advancement of evaluation indicators, depth of mechanism disclosure, and dynamics of carrying capacity evaluation.

    Red tourism, as an important way to inherit revolutionary culture, can promote the patriotism education publicly and improve the economic development of old revolutionary areas. This paper studies the spatial distribution and heterogeneity of influencing factors of 763 scenic spots in 300 published red tourism classic attractions of China, by constructing a theoretical framework system, spatial analysis methods and regression models, so as to put forward the development mode and countermeasures. The results show that: (1) The spatial distribution of classic red tourism scenic spots is affected by four subsystems: resources, environment, society and economy. (2) In terms of spatial distribution, the core areas are more dispersed compared with other tourist attractions, which presents a pattern of seven first-class core areas, seven second-class core areas, two contiguous second-class core areas, low-density, lower-density areas and so on. The spatial correlations are quite different, and the correlation effect weakens with the reduction of spatial scale. (3) The influencing factors of classic red tourism scenic spots are different in different regions. The influence degree is red tourism resources > altitude > policy intensity > slope > transportation facilities > market demand > resource linkage > consumption level. (4) In the future, the construction of classic red tourism scenic spots should focus on the development mode and countermeasures of network, node, corridor, symbiosis linkage and cross-regional coordination. The conclusions can provide scientific decision-making basis for the red tourism development, management and cross-regional cooperation.

    The scientific evaluation of urban-rural integration is the core content of urban-rural integration, and it is the foundation for establishing and improving the institutional mechanism of urban-rural integration. Based on the logical line of "connotation identification-theoretical analysis-system reconstruction", this paper carries out the review of urban-rural integration evaluation including concept connotation, theoretical basis, evaluation index, evaluation method, evaluation scale, spatio-temporal differentiation, and mechanism analysis. At present, the academic understanding of the connotation of urban-rural integration is basically the same. The evaluation index selection of urban-rural integration shows multidimensional and multi-attribute characteristics, but the index system construction has not broken through the static characteristics. Quantitative evaluation method is relatively simple. Generally, current research still remains at the macro scale, but lacks quantitative research from a micro perspective and comparative studies of different fusion modes. The spatial and temporal differentiation pattern and its mechanism of urban-rural integration need to be further deepened. Finally, this paper puts forward five prospects: (1) strengthening the construction of basic theory system and perfecting system research framework; (2) optimizing the multidimensional evaluation index system and identifying the development model of urban-rural integration; (3) deepening the flow mechanism of urban and rural elements and promoting the balanced development of urban and rural space; (4) strengthening the exploration of micro-scale details and improving the promoting mechanism of urban-rural integration; (5) strengthening the empowering role of the digital economy and innovating the development mechanism of high-quality urban-rural integration.

    Influenced by global change, temperature zone boundaries significantly have moved toward higher latitudes, especially the spatial distribution of subtropical zones is more sensitive to global warming, and the study of the spatial change characteristics of its boundaries is of great significance to understand the potential impact of global changes on natural landscapes. Based on the daily average temperature data from 1960 to 2019 from 74 meteorological stations in and around the Qinling Mountains, the 220-day contour of daily average temperature ≥10 ℃ continuous days with 80% guarantee and the 0 ℃ isotherm in January were selected as the northern boundary indicators of the north subtropics, and the trends of the boundaries of the Qinling climate zone under the background of climate warming in the past 60 years were explored. The results showed that: (1) The number of days with daily average temperature ≥10 ℃ in the study area during the period 1960-2019 showed a significant upward trend, with a change rate of 3.268 d/10 a; the average January temperature showed a weakly significant upward trend, with a change rate of 0.179 ℃/10 a. (2) The northern boundary of the north subtropics in the Qinling Mountains underwent a significant uplift in the past 60 years, with an average height of about 228.89 m. In terms of longitude, the northern boundary of the north subtropics in the middle section from 106°E to 111°E had the greatest change, with a rise of 308.81 m in the 60 years, which is significantly higher than the other two sections in the north and west (165.69 m in the east, 243.33 m in the west, and 267.01 m in the north). (3) The northern subtropical transitional zone of the Qinling Mountains climbed significantly in the 60 years and moved northward. Also, the "north" subtropical zone north of the Qinling Mountains climbed significantly and moved northward; the northern subtropical transitional zone of the Qinling Mountains climbed significantly and moved northward in the past 60 years. After the abrupt change in temperature, the northern subtropical transitional zone extended from the southern slope of the Qinling to the eastern part of the mountains and advanced northward into the Guanzhong Plain, and the role of the southern slope as the boundary between the north subtropical and warm temperate zones was weakened. With the climate warming, the northern subtropical transitional zone may continue to climb to higher elevations, and the northern subtropical transitional zone may be partially or integrally transformed into the north subtropical zone, and the north subtropical zone will be continuously distributed from the southern slope of the Qinling Mountains to the northern slope, and then the northern boundary of the north subtropical zone breaks through the Qinling Mountains.

    Tourism flow is an important indicator of industrial operation of red tourism destination, which plays a significant guiding role for the planning and management of tourism destinations. Based on 1286 online travel notes of typical travel websites (2000-2020), this paper uses ArcGIS spatial analysis method and social network analysis method to examine the spatio-temporal distribution and network structure characteristics of Jinggangshan red tourism flow. Results show that: (1) Tourism flow in Jinggangshan has formed a double-core and multi-point spatial pattern with "Ciping-Huangyangjie" as the center, while the temporal distribution presents a periodic seasonal difference, which is closely related to climatic and phenological changes, holiday system and other factors. (2) Tourism flow network in Jinggangshan presents a "core-periphery" hierarchical structure, and forms a "Longshi-Dujuanshan" dense flow area in the northwest-southeast direction, in which the tourist flow between Huangyangjie, Longtan and Ciping is most frequent, occupying the core position of tourism distribution hub. Erling, Tongmuling, Xiangzhou and Xiankou occupy the peripheral position of tourism flow network. The reasons for this hierarchical structure are mainly related to tourism transportation, supporting facilities, tourism attractiveness, geographical location and other factors. (3) The 11 nodes (scenic spots) in Jinggangshan tourism flow network can be divided into three categories: diffusion type, balanced type and agglomeration type. Among them, Ciping is the only diffusion-type scenic spot, Longshi is the only agglomeration-type scenic spot, while Huangyangjie, Longtan, Zhufeng, Dujuanshan and Maoping belong to balanced-type scenic spots. Among all the flow paths between 11 nodes, "Ciping→Huangyangjie" and "Huangyangjie→Longtan" are the core routes in the tourism flow network. In order to further promote the development of Jinggangshan red tourism in the new period, this research puts forward the following suggestions: (1) Strengthening the exploration of the revolutionary history and the connotation of red culture in scenic spots, develop diversified theme tourism products in different seasons and the characteristics of holiday system, so as to attract the deep participation of different groups, and obtain the understanding of the red revolutionary spirit. (2) Improving infrastructure and tourism route planning, enhance the integration degree of peripheral scenic spots (nodes) in the tourism flow network, and create a more systematic and balanced tourism network. (3) Allocating red tourism resources and other economic and social elements rationally within Jinggangshan region, and strengthen the driving role of the agglomeration-type scenic spots and core routes in the tourism flow network, so as to realize the integration and coordinated development for Jinggangshan red tourism.

    Abstract514)   HTML201)    PDF (7056KB)(117)      

    This paper explored the evolution of urban-rural spatial structure in China and its influencing factors since 1985 by using the urban-rural construction land and socio-economic data, and took Huaibei, a typical coal resource-based city, as a study case. The results showed that: (1) Generally, the urban-rural spatial structure in coal resource-based city develops in three stages. Firstly, the city mainly depended on the coal industry, and formed the "urban-mining-rural" ternary structure in 1985-2000. Secondly, the urban-rural spatial structure has evolved into a "center-peripheral" structure. In addition, the centrality of the major urban area is gradually highlighted. Thirdly, the urban-rural spatial structure evolved into a circle structure in 2010-present. Moreover, the speed of city transformation and development has accelerated. And the main urban area spread to the suburbs. (2) In essence, the evolution of urban-rural spatial structure was a process from dispersion to aggregation, and from separation to integration. (3) Management system of mining city, urban-rural industrial structure, municipal transportation network and policy system interacted to promote the evolution of urban-rural spatial structure in coal resource-based cities.

    The spatial optimization of red tourism resources utilization based on the resilience of "ruralism-ecology" system: A case study of Dabie Mountains Old Revolutionary Base Area
    ZHU Yuan-yuan, WANG Zi-wei, GU Jiang, YU Rui-lin
    JOURNAL OF NATURAL RESOURCES    2021, 36 (7): 1700-1717.   DOI: 10.31497/zrzyxb.20210706
    Abstract502)   HTML138)    PDF (5021KB)(108)      

    The red tourism resources utilization and development of tourist destination have a strong disturbance to human-earth areal system. Based on the resilience evaluation of "ruralism-ecology" system, this study presents a spatial utilization pattern of red tourism resources, which is conducive to promoting the development of red tourism resources and regional sustainable development mutual win-win situation. Taking the Dabie Mountains Old Revolutionary Base Area as an example, we constructed a resilience level evaluation system of the "ruralism-ecology" system of red tourism from four aspects of economy, society, culture and ecology, and identified the spatial characteristics and types of red tourism resources. The results showed that: (1) The resilience of "ruralism-ecology" system in each county was mainly at the middle and low levels, characterised by "high in the middle and low in the surroundings". (2) The resilience of subsystems in the region was barely coordinated, and the coordination of county-level administrative units presented an "olive-shaped" hierarchical structure with more counties at medium level and less counties at high and low levels. (3) The cold spot and hot spot areas of red tourism resources located on the north and south sides of the Dabie Mountains and the central part of the study area, showed a pattern of "large agglomeration, and small dispersion", which were divided into 5 clusters based on their scale and influence. (4) In areas with high concentrations of red tourism resources, the resilience of the "ruralism-ecology" system can be developed to a higher level through the reconstruction of internal elements. In the low- and medium-density areas of red tourism, the resilience of the "ruralism-ecology" system was weak in absorbing and adapting to external disturbances, which inhibited the development of red tourism resources. According to the evaluation results, the spatial pattern of red tourism resources utilization of "three regions, two belts and three cores" can be constructed preliminarily, and differentiated suggestions were put forward from the perspective of "ruralism-ecology" system resilience in different regions. The research results aim to mitigate the interference of the development of red tourism resources to the "ruralism-ecology" system.

    Abstract488)   HTML2)    PDF (2023KB)(0)      

    Xinjiang is one of the most important resource treasure houses and energy bases in China. How to construct a clean energy system under the guidance of carbon peak and carbon neutrality goals is related to national energy security. In this paper, we summarize reserves and distribution of main energy sources in Xinjiang, comb the current situation of energy production and consumption, analyze main problems faced by energy transition, and put forward pathways towards a cleaner energy system with relevant countermeasures and suggestions. It is shown that: (1) Fossil energy accounts for more than 85% in the existing energy system of Xinjiang, making the carbon emission reduction task arduous. (2) Wind and solar curtailments are an acute problem of Xinjiang at present, and the electricity curtailment rate is higher than the national average. (3) To promote the green transformation of Xinjiang's energy system, we must lower the growth rate of coal consumption, accelerate the construction of hydro-solar-wind-storage integrated power system, expand the channel of "Xinjiang's power transmission", advance the course of "electrified Xinjiang", and develop CCUS and new energy storage technologies. These findings can provide reference for Xinjiang to achieve the carbon peak and carbon neutrality goals.

    Tourism resources, the basic elements of tourism activities, determine the benefits of the development and utilization of tourism resources. The relationship between tourism resources and major national strategies has become increasingly close. Establishing a new viewpoint of tourism resources is a re-understanding and re-practice of regional development practices, which can put forward a new topic for tourism resources research. We sorted out and summarized the development context of tourism resources research under the traditional view of tourism resources. The results showed that: (1) The research contents of tourism resources are constantly enriched, and the research directions are becoming more and more diversified. Basic research actively makes great contributions to serve the national major strategies, as well as regional economic and social development. To a certain extent, the positive interaction between "theory guides practice" and "practice enriches theory" has been realized. (2) The new concept of tourism resources refers to the dynamic process of people integrating, configuring, reorganizing and optimizing tourism resources from different sources, levels, structures, and contents under the background of scientific and technological progress, changes in value concepts, increased tourism demand, and per capita income. It is regarded as an active response of people's cognition to the changes of tourism resource characteristics. The new outlook on tourism resources is a fundamental breakthrough to the traditional view of tourism resources, presenting new viewpoints on resource value, new resource utilization, new resource development, new resource benefits and new resource space. (3) This paper constructs a "five-dimensional integration" tourism resources research system from a new perspective of tourism resources, especially the value conversion of tourism resources, the sustainable use of tourism resources, the integrated development of tourism resources, the regional benefits of tourism resources, and the spatial reconstruction of tourism resources. It aims to strengthen the cross-regional aggregation, competition and integration of tourism resources, and to reveal the interaction mechanism of the development and utilization of cross-regional tourism resources. (4) There are some new problems and topics in the development and utilization of tourism resources in the new perspective of tourism resources. The integration of multiple disciplines and the introduction of new methods is an inevitable trend for comprehensive, dynamic, regional and systematic research on the development and utilization of tourism resources.

    LA Li-qing, XU Fei-fei, HE Yun-meng, HAN Lei
    JOURNAL OF NATURAL RESOURCES    2021, 36 (7): 1647-1657.   DOI: 10.31497/zrzyxb.20210702
    Abstract471)   HTML175)    PDF (1198KB)(110)      

    Taking Jinggang Mountain Scenic Area as a case, this study collected and analyzed the travel notes of this scenic area from We adopt big data analysis and qualitative text analysis methods and introduce the theory of value co-creation to explore the value co-creation mechanism of red tourism development from three dimensions (resources, practices and values). The results show that the value co-creation resources of red tourism scenic spots include historical and cultural heritages, natural landscape resources and iconic landscape symbols. Through practical activities including red culture experience, learning and training activities, and interpretation service experience, tourists gain knowledge of red history and culture, build an emotional connection with red culture and form the values of patriotism and identification with the country. This verifies the realization of the educational function of red tourism. On the other hand, the existing value co-creation practice of red tourist attractions is still limited. The value co-creation mechanism of red tourism development constructed in this study integrates the demand of tourists, the support service of scenic spots, and the possible value co-creation practice, which has practical significance for improving the participation of tourists and realizing the value co-creation of red tourist attractions.

    Negative effects of massive intercity population movement on the security of urban agglomerations
    NIU Xin-yi, YUE Yu-feng, LIU Si-han
    JOURNAL OF NATURAL RESOURCES    2021, 36 (9): 2181-2192.   DOI: 10.31497/zrzyxb.20210902
    Abstract471)   HTML204)    PDF (2786KB)(79)      

    This paper explored the characteristics of intercity human mobility and the 'negative effects' of massive intercity population movement in China by using mobile internet positioning big data. Two travel periods of Baidu Migration data were selected involving Spring Festival and usual travel time. Based on two mobility indicators, i.e., movement scale and movement scope, the spatial characteristics of intercity population movement were measured by local spatial autocorrelation. With a vital public health emergency, linear regression models were used to measure the differences in the negative effects of the national intercity population movement on different cities and urban agglomerations in China. It is found that three major urban agglomerations, namely, the Yangtze River Delta, the Pearl River Delta, and Beijing-Tianjin-Hebei, are the most significant high-value clustering area of mobility in China. Urban agglomerations and megacities are accompanied by higher risks of negative effects for their super mobility. First, the megacity-centered urban agglomeration will have a more significant negative consequence when it is affected by the negative effects of intercity mobility. Second, the megacity-centered urban agglomeration will significantly spread the negative effects through intercity mobility. It is proposed that the security of urban agglomeration should firstly guarantee the security of mobility. The security of urban agglomerations should be reflected in the resilience of intercity mobility networks. In the process of new urbanization, the development strategy of urban agglomerations needs to focus on the mobility and security of urban agglomerations from the perspective of territory spatial security.

    The urban system is faced with more uncertain risks and unknown disturbances in the coming future, which requires that the urban safety and disaster prevention planning should carry out adaptive adjustment in terms of target object, strategic positioning, technical means, planning concept, etc., so as to achieve regional security and stable development through flexible urban design. In this paper, we summarize and comment the theoretical development and practical exploration of resilient city. Combined with the construction of territorial planning system after "multi planning integration" in China, we reconsider the connotation characteristic, process structure, form content and public governance of resilient planning under the background of territorial governance. Then we put forward practice outlook of urban resilience and safety planning from four aspects, including deepening the theoretical construction and mechanism research of resilient city, changing the design thought and practice flow of planning, improving management and control transmission and scale governance in the practice, and focusing on the grassroots governance and public participation in resilience design. All the efforts are contributed to promote the modernization of urban public security governance construction in China.

    Territory spatial planning of Western China from the perspective of national security: Perfect system and basic orientation
    YANG Yong-chun, ZHANG Wei, CAO Wan-peng, MU Yan-jie
    JOURNAL OF NATURAL RESOURCES    2021, 36 (9): 2264-2280.   DOI: 10.31497/zrzyxb.20210907
    Abstract440)   HTML216)    PDF (1812KB)(77)      

    At present, China's territory spatial planning attempts from top to bottom to resolve or relieve the key issues from macro level as far as possible which has arisen since the reform and opening-up such as the ecological environment, resources restriction, the conflict of man-land relationship, multiple management and the authority of spatial plans. Although China's territory spatial planning system, organization framework and technical regulation have so far formed relatively reasonable "universality" norms, at the strategic level, the discussion of regional "individuality" issues in the context of national security is still lacking. Facing the needs of the country and the special situation of Western China, we should establish a cross- province and cross-basin territory spatial planning of this region based on national security strategies. To ensure national security, territory spatial planning of Western China at the strategic level should focus on the following: (1) In theory, based on the perspective of national security, we proposed to construct the cross-province and cross-basin territory spatial planning of Western China. (2) In practice, we recommend formulating the "territory spatial planning of Western China-ecological security" of specialized national territory spatial planning which takes ecological zone, nature reserve as the core in spatial scale. What's more, based on the border and support line, we should carry out "territory spatial planning of Western China-survival security" of specialized national territory spatial planning, or determine the detailed rules and regulations of national defense security in spatial planning. In addition, taking the urban system as the organizational context, we should set up "territory spatial planning of Western China-life security" of specialized national territory spatial planning which is relying on main transportation lines, or determine the detailed rules and regulations of the harmonious society construction in Western China. Besides, following the divisions of the Main Functional Areas, we should formulate "territory spatial planning of Western China-production security" of specialized national territory spatial planning which is focusing on the regional central city and urban agglomeration, or determine the high-quality economic development in the western region. We should also restructure the ecological space, survivable space, living space and production space. (3) In particular, we recommended strengthening the construction of border towns or villages, and establishing the "sanxian" (three lines) construction in the New Era, "the key construction belt around the Qinghai-Tibet Plateau" in the western region, which can meet the national security needs of limited globalization and achieve "dual circulation pattern" in the post-epidemic period. On the whole, the territory spatial planning of Western China should be different from that of the eastern and central regions. We should not impose uniformity on the implementation of the policies.

    With the transformation brought by the renewal and reform of territorial space planning, the improvement of the value of territorial ecological space, the construction of security pattern and the integrated development of multiple elements are becoming more and more important. The establishment of the national territory development planning system is the great ecological significance, and ecological priority is the core value of the formation of the national territory development planning system. Among them, the ecological restoration planning at the county level is an important part of the current national territory development planning. This study takes the land space of Weiyuan county, Sichuan as the research object, analyzes its serious problems of ecological resources destruction, ecosystem disruption, and low ecological efficiency in the background of industrialization and urbanization. It is pointed out that the construction of ecological security pattern is the goal orientation of national territory ecological restoration planning, and the evaluation index system of coupling degree is constructed by using the coupling method of eco-socioeconomic system. From the three aspects of the restoration of ecological elements, the optimization of ecological structure and the promotion of ecosystem value, combined with the typical ecological engineering technology, the ecological restoration security pattern composed of point, line and area is constructed, and the countermeasures of ecological management and restoration are proposed. The results show that: (1) The ecological restoration planning of counties has the characteristics of multi-level objectives, system complexity and diversity of approaches, and the response planning countermeasures can be put forward from the macro, meso and micro levels. (2) The coupling degree of eco-socioeconomic system in Weiyuan fluctuates between 0.457 and 0.497, and the ecosystem and socioeconomic system are now in an antagonistic period and have a development trend in the running-in period. (3) According to the calculation results of coupling degree, comprehensive efficacy and index influence degree, the overall pattern of ecological restoration of "multi-corridor and multi-point, two veins and two rings, one screen and two areas" can be constructed. The study puts forward the special planning methods and practical application of ecological restoration at the county scale, which can provide new ideas and methods for the current national territory spatial ecological restoration planning system of counties.

    As a typical cultural phenomenon throughout the progress and development of modern and contemporary Chinese society, the writing, construction, inheritance and other topics of red memory at the macro level have been widely concerned and discussed. However, the research on red memory on the individual level is relatively deficient and requires to be promoted. Therefore, this paper takes Yan'an urban core area, which is rich in red resources, as a case study. With the help of generation research method, through in-depth interviews with 36 local residents, this paper interprets the red memory differences among three generations of Yan'an urban residents, and explores the "macro-micro" construction path and results of red memory. The results show that the macro level of memory elements mining, narrative expression and resource activation construct the coding, selection and consolidation process of residents' red memory, promote the local residents to generate red memory content with characteristics of the times, and finally construct the authoritative, functional and reflective red memory system of the old, middle and young generations. The results reflect the significance of the social forces of memory construction and the changing times in shaping the content of individual memory, and provide a theoretical reference for standardizing the practice of red memory and promoting the inheritance of red memory.

    The symbiotic development of red tourism resources and other types of tourism resources is an inevitable phenomenon of market allocation of resources, so the research is of great significance. Taking the tourism resources of Hunan province as objects and the scenic spots as symbiosis units, we identified scenic spots into five types of red-dominated, green-dominated, blue-dominated, patina-dominated, and entertainment-education-dominated through the type structure of tourist resources. Calculating the symbiosis potential energy based on the scenic spots' quality index and the convenience index between them, and using Ucinet and ArcGIS software analysis based on social network theory, we found that there are five levels of symbiosis potential energy in tourism resources of Hunan, which express properties of the primary contact center of pure altruism, the secondary contact center of altruism, the important contact point of symmetrical mutual benefit, the general contact point of asymmetric mutual benefit, and the loose contact point of pure egoistic, while red tourism resources showed an absolute advantage in symbiosis potential energy. Red tourism resources play a significant organizational role in the tourism resource symbiosis system, which is composed of five symbiosis communities. Among them, one community, with the advantage of Changsha-Zhuzhou-Xiangtan (CZT) red tourism resources, has the closest internal connection and the best symbiosis potential energy, while the internal connection in the other four symbiosis communities decreases in the order of the first one co-constructed by tourism resources of patina, red and blue in southern Hunan, the second one co-constructed by tourism resources of green and patina in western Hunan, the third one with green-advantaged tourism resources in southwestern Hunan and the last one with patina-advantaged tourism resources in the area around Dongting Lake. The symbiosis community with the advantage of red tourism resources in CZT has connections with all the other four symbiosis communities, and it has a closer contact with the one which is co-constructed by tourism resources of patina, red and blue in southern Hunan. There is a closer relationship between the symbiosis community co-constructed by patina, red and blue tourism resources in southern Hunan and the symbiosis community with green-advantaged tourism resources in southwestern Hunan. Red tourism resources are the main body of the core area of the tourism resources symbiosis system in Hunan. Among 53 scenic spots in the core area, 18 are red-dominated scenic spots, accounting for 33.96%; 27 belong to the symbiosis community with the advantage of red tourism resources in CZT, accounting for 50.9%. The research results show that red tourism resources perform strong support and synergy for the development of Hunan's tourism industry, and reflect the unique value of promoting regional high-quality development.
