"Three rural issues" (issues concerning agriculture, rural areas, and farmers) is an important mainline of the CPC's centennial course of party building and China's urban-rural development. In order to solve the "three rural issues" in the New Era and promote the implementation of rural revitalization strategy, we hereby invite ten experts in the research field of "three rural issues" and rural revitalization research to conduct interviews. The interview mainly focuses on three perspectives: Historical process and institutional context, urban-rural system and cross scale space, and the integration of policy theory, technical methods, and rural construction practice. It revolves three main lines: The strategic stage and institutional changes of "three rural issues", the essence of "three rural issues" and the ways to solve new "three rural issues", and the rural revitalization mechanism and rural construction practice. The main conclusions are as follows: (1) The essence, key areas, and institutional mechanism innovation of the "three rural issues" in the context of spatio-temporal processes and institutional contexts. It is necessary to grasp the laws of "three rural" (agriculture, rural areas, and farmers) and diagnose the "three rural issues" from the perspective of urban and rural regional systems and even the global perspective space. The "three rural issues" is an optimization decision-making problem for improving the functions of rural regional systems within the overall framework of urban and rural regional systems. The imbalance in urban-rural development and insufficient rural development are the concentrated reflection of the "three rural issues" in the New Era. The crux of the "three rural issues" lies in the uncoordinated development of "human, land, and industry". The core goal of China's "three rural issues" in the new development stage is to move towards the common prosperity of farmers and rural areas. The corresponding development system and working mechanism of "agriculture, rural areas, and farmers" need to grasp the two "bottom lines", do a good job in the two "connections", and promote the two "integrations" in key areas such as national food security, farmers' livelihood development, modern agriculture and rural development, rural revitalization, and urban-rural integration development. (2) The theory of rural revitalization and the rural spatial planning under the requirements of urban-rural system interaction and people's common prosperity. The research and solution of China's "three rural issues" are rooted in the geographical theory of territorial system theory of human-environment interaction and location theory, the sector economy theory and the economic cycle theory, as well as the theory of development economics, sociological function theory and social conflict theories. In the research practice of the "three rural issues", land use transformation theory, rural reconstruction theory, rural development multi-body and multi-pole theory, interface theory, rural attraction theory, and rural sustainability have also been developed. The urban-rural integrated development and the common prosperity of the people should be the result of balanced regional development and Chinese path to modernization. The folk expression of "making rural life attractive" and the strategic goal of "basically realizing rural modernization by 2035" are mutually "exterior-interior" relationship, which can be comprehensively explained from the following three aspects: The spatio-temporal differences and path differentiation of rural settlement evolution and multi-functional transformation, and the phenomenon explanation of rural gentrification and the theoretical application of rural attraction in the context of urban-rural interaction, as well as the theoretical significance and practical path of rural modernization under the guidance of rural sustainability science. Improving local quality is an inherent requirement to meet the people's needs for a better life, and it is an essential requirement and general law of rural revitalization driven by innovation. As the edge of the national urban-rural system, rural areas face constraints such as segmentation, remoteness, low density, and insufficient heterogeneity dividends in improving local quality. Therefore, to improve local quality of rural areas, it is necessary to adapt to and alleviate the relative inefficiency of rural geography, and its important promotion paths include the characteristic development based on endowment, digital transformation and rural agglomeration centered around cities and towns. Guided by spatial planning and taking into account the integrated functional development of production-living-ecological spaces in rural areas, as well as the integration of urban and rural space through spatial planning, through promoting the quality of living space through comprehensive land improvement, assisting in the realization of multifunctional value in agricultural space through refined management, ensuring the sustainable use of ecological space through systematic protection and restoration, which is a solid foundation for rural revitalization and the construction of a new urban-rural relationship. (3) The path mechanism and technical support for the comprehensive rural revitalization and rural construction under the new needs of ecological civilization construction and governance modernization. Comprehensive rural revitalization requires the revitalization of industries, the reform of land, the development of human well-being, and the intelligent updating of technology. First, the essence of operating rural areas is the rational allocation of resources as the object of factors. It is necessary to integrate the high-quality development of agriculture with the high-quality and livable rural areas, promote the interaction and integration of urban and rural systems, actively link natural science, engineering technology innovation, and institutional innovation from the perspective of the big food concept, and implement food safety and important agricultural product supply security. Second, facing the new demand of rural sustainable development and governance modernization, we should innovate the property right governance integration mechanism of rural land system, especially actively build a rural green development mechanism with farmers' participation and an external benefit sharing mechanism of ecological environment governance. Third, it is urgent to break through the barriers that farmers share the gains from the appreciation of rural assets, fill the gap between small farmers and modern agriculture, and establish a concept of county governance that meets the needs of Chinese path to modernization. Fourth, rural construction is an organic combination of the governance of public spaces by the state and the daily life practices of farmers. Through the theory and technology of "computational" rural areas, effective connection and information sharing between the state and rural areas can be achieved, promoting coordinated development from micro to macro, and from local to whole. And we should achieve the aim of building livable, suitable for work, and beautiful rural areas, through multi-level main body co-construction, co-governance, and management. To sum up, the interview views can provide theoretical reference and decision-making reference for the "three rural issues" work innovation and rural revitalization practice towards Chinese path to modernization.

Commons often lead to a "tragedy of the commons" because they can be accessed freely, that is, overexploitation of commons usually leads to resource degradation. Since Garrett Hardin published an article "Tragedy of the Commons" in Science in 1968, there has been an increasing number of studies on commons governance to avert the tragedies. With the development of urbanization, industrialization and increase of population, the overexploitation of natural resources by human activities has become increasingly serious, such as air pollution, carbon emissions, marine pollution, and depletion of mineral resources In order to promote the sustainable use of commons, it is necessary to review the theoretical and practical progress of the "tragedy of the commons" theory and its related study of governance. Therefore, this paper first reviews the theory of "tragedy of the commons". Then, obtaining 43830 paper, documents, etc. from Google Scholar that have cited Harding's articles by the end of 2020, this paper analyzes the keyword time series of these citing literatures, and combines with the development context of the research to summarize the progress of theory. We found the theoretical progress includes five aspects: examination of "Tragedy of the Commons" theory, analyses of the property right system of public resources, multiple governance types of commons, sustainability analysis of Social-Ecological Systems (SES), and governance of global resources. Their inspirations for sustainable governance in China are: (1) There is no "panacea" for resource governance, and it is necessary to explore the "diversification" of the system; (2) Accelerate the improvement of the property rights system for natural resources, and build a property rights system for natural resources owned by all the people, based on China's national conditions; (3) Implement multiple governance types on natural resources and build a collaborative, co-governance and shared environment; (4) Implement systematic governance of natural resources to promote the harmonious coexistence between human and nature; (5) Govern global resources through institutional innovation, and build a community with a shared future for mankind. The review of the development of "the tragedy of the commons" and its governance can provide important theoretical and practical enlightenment for the sustainable development of China's resources and environment and the modernization of governance capabilities. This also indicates an interdisciplinary academic innovation path and proposes potential research directions.

In the era of digital economy, the tourism development model based on traditional natural and human resources can no longer effectively meet the diversified and personalized needs of tourists. Some non-traditional tourism resources in digital platforms have attracted a large amount of attention capital and converted into tourism flows, which greatly expands the content and boundaries of tourism resources. The emergence of the flow economy has not only profoundly affected the development model of tourism, but also posed new challenges to the theory and practice of tourism resource development. Interviews show that: First, the formation of the flow economy is not a coincidental phenomenon; although the spread of flow leads to the expansion of attention capital scale and drives tourism development, the core of tourism development lies in tourism resource endowment, tourism service quality, government support and guarantee, etc. Second, the flow economy drives the recombination, agglomeration and diffusion of tourism supply and demand factors, and quickly caters to the individual needs of tourists, while whether the tourism industry can adjust its service supply capacity in response to changes in tourist demand becomes the key path and mechanism for the flow economy to promote tourism development. Third, in order to promote the flow economy to empower the high-quality development of tourism, it is necessary to combine effective market and active government, and to establish the brand of tourism. We can also make full use of the spatial effect of the flow economy to promote the collaborative development of regional tourism. Finally, after the tourism boom triggered by the flow economy, it is also necessary to calmly consider the mismatch of resources, negative environmental effects, cultural conflicts and contradictions between short-term hotspots and long-term investment. Only in this way can tourist destinations follow a sustainable development path.

Low-carbon development of territorial space provides the basis for realizing the strategic goal of the carbon peak and the carbon neutrality. The city region is a key regional unit with dual attributes of target transmission and strategy implementation in territorial space. It is of great significance to promote the realization of the "dual carbon" goal and to reveal the level of carbon emissions and spatial difference of low-carbon development efficiency of territorial spatial in cities for shaping the low-carbon sustainable territorial spatial pattern. This study explored the methodological system for measuring carbon emissions in territorial space, analyzed the characteristics of spatial differences in the efficiency of low-carbon development in city territorial space from economic, social and ecological dimensions based on the measurement results, further proposed a spatial governance-oriented optimization strategy, and finally conducted an empirical analysis using Suzhou city as an example. The results showed that: (1) The built carbon emission measurement method and low-carbonization development model of city territorial space can effectively measure the carbon emission characteristics of Suzhou city and its spatial differences in low-carbonization development efficiency. (2) The total carbon emissions in Suzhou in 2020 were 238 million tons, and the high-value parcels of carbon emissions were concentrated in various industrial agglomerations, while the low-value parcels were dispersedly distributed in the rural areas and the main areas of various carbon sinks. The development efficiency of territorial spatial low-carbonization varied significantly at different scales, mainly reflecting regional differences at the county and district scales and urban-rural differences at the township scale. Meanwhile, regions with relatively high levels of economic and social development had higher economic and social low-carbonization development efficiency, but ecological low-carbonization development efficiency was often lower. (3) According to the different spatial types of districts and townships, this paper promotes the transformation of green development of economy and society, bringing into play the role of territorial spatial planning in emission reduction and carbon sequestration, and building a composite and coordinated, low-carbon and sustainable territorial spatial pattern.

As the coproducers and beneficiaries of ecosystem services, stakeholders play an important role in the supply, demand and decision-making of ecosystem services, and are crucial for exploring the social relevance and potential social effect of ecosystem services. It is important to evaluate ecosystem services from the perspective of stakeholder's perception, reveal the influencing factors, and balance the multiple ecological benefits of different stakeholders. Based on the theoretical framework and practical progress of ecosystem services at home and abroad, we summarized the concepts of stakeholder and perception, introduced the application of stakeholder's perception in ecosystem service research. Then, we analyzed the characteristics of identifying stakeholders, data acquirement and evaluation methods. Furthermore, we explained the influencing factors and mechanism of stakeholder's perception of ecosystem services. Under the guidance of the concept of social equity, decision-making participation and sustainable development of ecosystem services, we built a research framework taking stakeholders as core elements for the interaction and integration of social perception assessment, social effect analysis and policy-making application, and then effectively linked the natural ecosystem and human social system. In the future, we should focus on: (1) clarifying the diversified social needs and differences of ecosystem services, (2) deepening the role of multi-source big data in multi-scale ecosystem service perception assessment, (3) expanding the application of spatial analysis methods, and (4) revealing the influential mechanism of ecosystem service perception differences.

At present, the urban renewal action of Wuhan has changed from large-scale demolition and construction to the era of "retaining, replacing and dismantling". The transformation mode has also changed from local transformation to continuous renewal. In the current era, it is particularly important to identify urban "retained, replaced and demolished" units intelligently. Recently, the combination of AI and remote sensing has been widely used for the identification of typical surface features of natural resources, cultivated land protection, and law enforcement supervision. In this paper, we combine AI and remote sensing to identify "retention, reconstruction and demolition" units. First, we establish training samples of the "retention, replacement and demolition" unit, then use the deep learning network to establish the artificial intelligent model, and finally select the remote sensing data to carry out the identification of "retention, replacement and demolition" unit in Wuhan. The integration of remote sensing and deep learning improves work efficiency of the identification of "retaining, replacing and dismantling" units, and provides scientific basis for solving the pain points in urban renewal.

Inter-government ecological collaborative governance is an important means to promote the modernization of the ecological governance system and governance capacity in the basin, but the justification logic of its superiority over the traditional territorial governance model is not clear, which makes local governments lack confidence in the effectiveness of ecological collaborative governance. The implementation of the inter-governmental ecological collaborative governance mechanism faces the problems of lack of legal norms, lack of governance subjects and lack of endogenous power. Taking the cost-benefit as the driving analysis frame, this paper constructs the game model of ecological territorial governance and the game model of inter-governmental ecological cooperative governance, which can clarify the behavior logic and influencing factors of the local government in the river basin ecological governance. The study found that the central government is an effective leading force in promoting the implementation of the ecological collaborative governance model; the added benefit of ecological governance created by inter-governmental synergy also proved that the ecological collaborative governance model can improve the overall ecological quality of the river basin; maximizing the benefits of ecological governance and ensuring the fair distribution of benefits, which is as dual goals of watershed ecological governance.

Under the background of global food security issues, food waste has become the focus of all countries. Household is one of the significant sources of food waste. Along with the aims to achieve carbon peaking and carbon neutrality goals and promote the construction of ecological civilization, the reduction of household food waste is of substantially economic, social and ecological significance. Noted that domestic research on household food waste is still weak, systematic review of domestic and international research on household food waste can offer important theoretical and practical insights. A systematic literature review was conducted, following a thread of concept, theoretical framework, measurement methods, sub-themes. This review aims to summarize the shifts in connotation, advances in methods and theory concerning household food waste. This study argues that China's household food waste has its own characters owing to its historical and social factors, food culture and urban-rural divide. Academic research should be carried out in relation to the Chinese society, culture and institutions. The paper figures out the research prospects on food waste in Chinese families under the backgrounds of new environment and new technology. They include the difference between urban and rural household food waste, the influence of regional food cultures on China's household food waste, the relationship between Chinese family characteristics and food waste in the New Era, the influence of Chinese socio-cultural psychology on household food waste.

The change of construction land use is an important reason for the change of carbon source/sink. How to optimize the spatial allocation of urban construction land in China's provincial-level regions to drive carbon emission reduction is an important topic under the background of the dual carbon strategy. In this paper, the proportion of the first city and Herfindahl index are used to measure the concentration degree of spatial allocation of construction land, and the carbon emission level is characterized by the carbon emissions per unit of construction land area. Based on China's provincial panel data from 2000 to 2020, this paper uses two-way fixed effect model to test the impact mechanism of the concentration of spatial allocation of construction land on carbon emissions. The results show that: (1) The centralized spatial allocation of urban construction land in provinces has significant carbon emission reduction effect. (2) From the perspective of functional land, the centralized spatial allocation of industrial, residential, and service land can reduce carbon emissions. From the perspective of action intensity, industrial and service land is larger, while residential land is slightly smaller. (3) Energy efficiency is an important mechanism for the centralized spatial allocation of provincial urban construction land and its functional land to affect carbon emissions. (4) The coupling and coordination of the centralized spatial allocation of various types of functional land will have a multiplier effect on carbon emission reduction by enhancing energy efficiency.

Through a review of research literature on the forest resources balance sheet, it is found that there are still problems of completeness, such as controversial measurement of resource liabilities and missing measure of ecological product values, and operational problems, such as unclear compilation subjects, ambiguous reporting cycles, and difficulty in replicating and promoting the statements. Therefore, this study follows the principle of "complete content, high quality, and easy operation". First, from two aspects of the economy and the public welfare, we count the value of ecological products, which complements the connotation of resource liabilities from the perspective of intergenerational equity and sustainable development, and systematically summarizes the pricing methods of each item of forest resources to break through the accounting difficulties. Second, this study combines the four levels of the administrative system in China: provincial, municipal, county, and township, and constructs the system of "bottom table+auxiliary table+main table+general table", which comprehensively explains the process of report preparation, responsible units, reporting time and publication cycle. Finally, to serve the fiduciary responsibility of forest resource management of governments at all levels, the balance sheet of forest resource and the statement of changes are explored in Hubei province as an example.

Based on the panel data of park green space and social economy of 284 prefecture- level Chinese cities since 2000, we examined the spatio-temporal patterns and driving mechanism of supply and demand of park green space, using the coefficient of variation, exploratory spatial data analysis methods and econometric models. The results show that: (1) The total area of China's urban park green space increased significantly since the beginning of the 21st century. The average level of park green space per capita has been significantly improved, with obvious differentiation in cities with different regions. (2) The difference degree of supply and demand of park green space converged significantly. After 2010, the supply of park green space in Western China has increased significantly. The lower per capita area of some small and medium-sized cities in Northeast, Central and Western China was the main inducement to block the equalization of park green space. (3) The spatio-temporal evolution of supply and demand of urban park green space was comprehensively driven by multi-dimensional factors such as urban background, social economy and public policy. Both the level of urban population agglomeration and land development had negative impact. The improvement of economic development, industrial structure upgrading and optimal allocation of residential land played an important promotive role. The public financial support, improvement of transportation infrastructure and level of environmental protection had significant positive impact. The driving mechanism of each factor however was obvious heterogeneous. We should increase the total supply of park green space according to the local conditions of different cities, innovate the supply mode and supply form, and improve the operation and maintenance system of park green space. The research results can provide references for improving the supply and demand of urban park green space, and solving the unbalanced and insufficient supply of park green space.

The purpose of this study is to put forward the regulation innovation logic and path based on practices of territory space use conversion permits in China. The territory space use conversion permits include permits of resources allocation and permits of risk control. The problems and challenges of the territory space use conversion permits include: unclear setting of the permit conditions, incomplete legislative integration and incomplete supervision of permit procedures. The Chinese government should standardize laws, optimize procedures, and diversify mechanisms for territory space use conversion permits. These approaches are inevitable innovative logic for protecting the common interests of natural resource owners, implementing protection, restoration and management systematically, and improving the governance ability of territory space use conversion permits. This study suggests that the government innovation permits regulation should focus on four directions: enriching basic conditions of territory space use conversion permits, paying attention to connection of key process procedures, innovating tools of permits, and optimizing authority and responsibility for administrative review and decisions.

Boosting the internal impetus for rural development is key to promoting high-quality rural development and constructing livable, workable, harmonious and beautiful villages. To this end, existing studies call for neo-endogenous rural development through the collaboration of actors within and outside villages. However, most of the studies discuss this issue at the conceptual level, which still needs a systematic framework to provide action guide. Addressing the gap, this study combines the symbiotic theory and neo-endogenous development pattern, and builds a research framework with three dimensions of the symbiotic unit, symbiotic pattern and symbiotic environment. Taking the "Rural Operation" practice in Lin'an district in Hangzhou as the case, this study identifies the path and mechanisms of the symbiosis of multiple actors within and outside villages to realize neo-endogenous rural development. This study finds that: (1) Local forces, social forces and government forces constitute the basic symbiotic units, respectively assuming the roles of endogenous power, localized intermediary and platform constructor. (2) Neo-endogenous rural development is embedded in a multi-scale symbiotic environment of state, market and local spaces. Multiple action logics, including the state administrative logic, market economic logic and local cultural logic, exist in the environment. (3) In terms of the symbiotic pattern, symbiotic units need to build deep and multiple linkages with each other, establish shared values, and construct a governance system with formal and informal institutions, to enable the stability and sustainability of the symbiotic relationship. This study also provides practical implications for boosting the internal impetus for rural development and promoting rural revitalization, from the perspective of symbiotic theory.

The purposes of this study are to explore the zoning of grain production regions based on systematic conservation planning method, to analyze the encroachment of urban agglomeration expansion on high-quality farmland under the two scenarios of coordinated development and independent development of cities within the urban agglomeration, and to provide reference for regional grain production functional area identification, resource allocation optimization and spatial layout planning. The research methods are as follows. Based on the urban flow theory and PLUS model, the expansion of Pearl River Delta urban agglomeration in 2030 under the two development scenarios is simulated and predicted. Based on the concept of system conservation, the functional areas and reserve areas of grain production are identified, and the encroachment of different expansion results on grain production regions is analyzed. The results indicate that: (1) The simulation results of urban agglomeration expansion under the scenario of coordinated development of various cities in the Pearl River Delta are more consistent with the actual development trend. (2) Based on the concept of systematic conservation planning, the farmland in the study area is divided into functional areas for grain production, reserve areas for grain production, and other areas. (3) Compared with the independent development scenario, the expansion of urban agglomeration based on urban interaction will encroach less grain production functional areas and grain production reserve areas. In conclusion, the zoning method of grain production functional regions can coordinate the multiple goals of socio-economic development, farmland protection and food security, and can provide suggestions and basis for optimizing the development and protection pattern of territory space under the background of urban regionalization.

Urban-rural integrated development is an important way to coordinate the national strategies of new urbanization and rural revitalization. It is also crucial for Chinese-style modernization. To comprehensively tackle challenges facing the current urban-rural integration in China, explore the path of coordinated urban-rural governance, and clarify the strategies for urban-rural integrated development, experts from various fields were cordially invited to engage in in-depth discussions on pressing issues related to urban-rural iintegrated development. These issues include the trends and pathways of urban-rural integration in contemporary China, Innovation of institutions and mechanisms for urban-rural integration, implementation pathways for territorial spatial planning, emerging rural business models and rural transformation pathways, high-quality development pathways for urban-rural integration in different regions, and the path of promoting urban-rural integrated development through comprehensive land consolidation. These discussions aimed to advance theoretical research and practical planning of urban-rural integrated development in China. Attentions need to be paid in urban-rural integrated development in the New Era on: (1) The primary obstacles and innovative pathways in the institutions and mechanisms of urban-rural integrated development guided by comprehensive coordination and regional interconnectivity. Constructing an infrastructure and public service system that effectively connects and complements urban and rural areas, accelerating the coordinated development of urban and rural areas using counties as the carrier, and promoting the flexible governance of this population while concurrently achieving integrated governance of urban-rural natural and social system. Promoting cross-border governance, encouraging cooperation and assistance between eastern and western regions, and achieving regional-scale coordinated development between urban and rural areas. Underdeveloped regions in both Central and Western China should strengthen the linkage role of counties and small towns. This involves enhancing their attractiveness for the inflow of talent, technology, and capital, and driving the transformation of industrial structures towards digitization, intelligence, and low. In contrast, developed regions in the Eastern China should establish a spatial structure system with multiple focal points, network layout, and clear hierarchies. They should expand the breadth and precision of urban-rural factor mobility, and promote the transformation and upgrade of traditional infrastructure and public services, aiming for inclusive development. (2) Optimizing the allocation of resource elements driven by the "planning-utilization-consolidation" cycle in territorial spatial management to achieve shared urban-rural governance and rural reconstruction. Anchoring the spatial pattern of urban and rural development through territorial spatial planning, optimizing the urban-rural spatial layout during planning implementation. Ultimately, improving the spatial quality organic renewal and driving bidirectional flows of diverse elements between urban and rural regions. Place emphasis on rural functional provision, resource utilization orientation, and industrial development models, uncovering multifaceted rural functions including production, lifestyle, ecology, and landscapes. Exploring regionally adapted industrial integration models that enhance agricultural and rural development vitality through distinctive features and high efficiency gains. We also should enhance the leading role of comprehensive land consolidation policies, incentivize and support active private capital involvement, promote resource integration and value enhancement. Strengthening urban-rural industrial synergy and integrated development, and facilitating the orderly flow of urban-rural resource elements. (3) Enhanced awareness and innovative practices in targeted urban-rural governance and rural transformation supported by digital technology and intelligent platforms. Establishing an urban-rural data sharing platform helps bridge the "digital divide" in urban-rural integrated development and enables refined governance across urban and rural areas. Deeply apply the technologies like 5G, Internet of Things (IoT) to support the transformation and upgrade of conventional infrastructure. Expanding the coverage of digital devices in rural basic facilities, and utilizing digital technology to integrate cultural resources across urban and rural areas. Promoting the deep integration of the digital economy and the physical economy involves linking consumer markets through the internet and digital technology, establishing diverse channels for agricultural product distribution, and stimulating the transformation of consumption patterns and the enhancement of consumption capabilities for both urban and rural residents. Embedding digital technology into rural industry development and social governance processes to facilitate the intelligent transformation of agricultural production, digitalization of rural industry development, smartification of rural administrative affairs, and establishment of a digital grid for rural social governance. The aforementioned viewpoints can provide theoretical support and decision-making foundations for achieving the goal of urban-rural integrated development oriented towards Chinese-style modernization.

In recent years, the exacerbation of climate change poses a significant threat to cultural heritage protection in China. It is of both theoretical and practical significance to study the influencing mechanism and response mechanism of climate change influence on cultural heritage protection. This study analyzes the mechanism and process of mutual interaction of climate factors on cultural heritage, evaluates the influence and trend of future climate change on Chinese cultural heritage, and finally explores the interactive relationship among different stakeholders of Chinese cultural heritage protection. The results show the mechanism and process that the changes of various climate factors acting on cultural heritage are complex and diverse. The change of individual climate factors, the chain reaction triggered by the change of climate factor, and the interaction of different climate factors generally have a direct or indirect impact on cultural heritage. Moreover, solar radiation, temperature, humidity, air pollutants, precipitation and other climatic factors have affected Chinese cultural heritage to a certain extent, admittedly, but it is necessary to dialectically explore the impact of future climate change on Chinese cultural heritage. With the intensification of global warming and the appearance of extreme weather, the destruction of cultural heritage caused by the difference in temperature and freezing will be reduced, but the cultural heritage represented by ancient wooden buildings and grottoes will still face severe threats. Finally, the establishment of a network of stakeholders is beneficial to administrative departments, local governments, local communities, enterprises, tourists, researchers, and external pressure groups to play respective roles to jointly protect cultural heritage. Under the dual backgrounds of the intensification of climate change and the strategy of "cultural power", this paper is helpful to deepen the understanding of all circles on cultural heritage protection, and enrich the theoretical discussion about protection and utilization of cultural heritage.

Digital village is an important driving force for agricultural and rural modernization. It is not only the strategic direction of rural revitalization, but also an important part of the construction of digital China. On the basis of analyzing the spatial characteristics of Chinese digital villages, we match CHFS database with Digital Rural County Index, and use the threshold regression method to identify the income increase effect of rural households. The results show that: (1) The development of digital villages in China is unbalanced, presenting a decreasing trend from east to middle and west, but there is little difference between the north and the south; (2) The development level of the four sub-dimensions of digital villages is in the descending order of rural digital infrastructure, rural governance digitization, rural economy digitization and rural life digitization, and there is a large east-west difference between rural economy digitization and rural life digitization. At the same time, the total development level of digital villages and each sub-dimension are significantly correlated in space, and the HH and LL clustering characteristics are prominent. (3) Digital villages promote farmers' income through rural digital infrastructure, rural economy digitalization, rural governance digitalization and rural life digitalization, among which the income increase effect of rural economic digitalization is the largest. (4) The income increase effect of rural households is related to the education and income level of rural households, that is, the income increase effect of rural households with higher education is more significant, while that with lower income is not obvious, and even has a restraining effect. In addition, considering the development stage of the digital villages itself and the level of regional economic development, the digital village has a nonlinear impact on the increase of farmers' income.

Identifying the spatial structure of the rural regional system scientifically and systematically is the premise of proposing differentiated rural revitalization strategies. This is of important practical significance for thoroughly implementing the rural revitalization strategy and accelerate the integrated development of urban-rural areas. This paper takes Changsha county, Hunan province as the research area, constructs a rural development evaluation index system based on the rural regional multi-body system and the multi-level goals of rural revitalization, and integrates research methods such as gravity model, K-Means clustering, geographic detectors and spatial autocorrelation. Quantifying and identifying the spatial structure, including poles of rural revitalization, fields of village-town space, zones of rural development and urban- rural infrastructure networks, is composed of 137 administrative villages in Changsha county. The results show that: (1) The spatial differentiation of rural development level in the study area is the result of a combination of factors, which presents a circle structure weakening from the center of the town core to the periphery, and the spatial agglomeration effect is significant. (2) The closeness of supply and demand between regions is an important factor affecting the strength of spatial linkage, and the intensity of spatial connection based on factors can better express the needs and complementary pattern of regional development. (3) The "Pole-Field-Zone-Network" multidimensional analysis framework has strong applicability for the identification and division of the spatial structure of the rural regional system in the suburbs of the urban area. Finally, 11 rural revitalization poles, 3 village space fields, and 7 rural development areas were specifically determined and divided, and an urban-rural infrastructure network based on the "pole-field-zone" network structure was constructed. According to the spatial structure, this paper puts forward differentiated suggestions for promoting rural revitalization and urban-rural integration development.

The territorial space use regulation system is a crucial point and specific practice for the Chinese government to promote the modernization of territorial space governance system and governance capacity. Based on the theoretical framework of the construction of the territorial space use regulation system, this paper follows the dual guidance of institutional evolution and the needs of the times to explore the feasible path of territorial space use regulation system construction. The results show that: (1) The territorial space use regulation is a compound movement process of territorial resource allocation and regulation power operation. The lag of planning technology and the obstruction of regulation system will lead to the failure of space regulation. (2) The changes of China's territorial space use regulation system reflect the evolutionary law of the natural resource management system with Chinese characteristics. (3) The territorial space use regulation still faces difficulties such as the coordination of regulation subjects and the optimization of regulation systems. (4) The goal orientation of the construction of territorial space use regulation system should meet two needs, balance two sets of goals and coordinate the two pairs of relationships. (5) The construction of territorial space use regulation system should be carried out from the aspects of regulation power, regulation system and operational mechanism. In conclusion, the construction of territorial space use regulation system needs to adhere to the correct goal orientation, and take into account physical regulation and power regulation, as well as static systems and dynamic mechanisms.
