    Since the 1950s, driven by large-scale, long-term and continuous comprehensive investigations of natural resources oriented to serve national strategic needs, China's natural resources research has formed a comprehensive and integrated development characteristics, and the development process of "task with discipline" has also gradually created a more systematic resources science theoretical basis and empirical methodology system. Faced with the country's major demand for deepening the reform of the comprehensive management system of natural resources since the establishment of the Ministry of Natural Resources, promoting the establishment and improvement of an independent resources science discipline system has become an important task in the field of natural resources research in China. This article systematically sorts out the development process of comprehensive investigation and research on China's natural resources from the 1950s to the early 2000s, focusing on the key development directions and characteristics of different periods. Combining the summary and prospects of historical opportunities in different periods, we believe that China's natural resources research has formed a national demand-oriented and leading discipline development trend. In the future, we should continue to adhere to the comprehensive research paradigm featured by multi-disciplinary integration; open up new perspectives on resources science system research with Chinese characteristics; accelerate the formation of a complete discipline system; improve the talent training system of resources science; strengthen the study of the discipline history of resources science; determine the relationship between resources science and geography, geology, ecology, environmental science and other related disciplines; actively introduce the big data theoretical framework and technical advantages to innovate "Natural Resources Big Data" or "Resource Utilization Big Data" and other related theories and technologies and to establish a dynamic evaluation method for the process of natural resources development and utilization; provide the background of natural resources and its comprehensive impact assessment with the ecology and environment for ecological civilization construction and sustainable development strategies support for decision-making; explore and analyze natural laws, socio-economic laws and the systematic association between the two in the process of natural resources utilization.

    The Report of the Nineteenth National Congress of the Communist Party of China proposed that building a New Era of socialism with Chinese characteristics puts forward new demands for comprehensive research and management practices of natural resources. Since the completion of large-scale comprehensive scientific investigations and researches of natural resources in the 1990s, comprehensive research on natural resources has gradually become the focus of attention in the field of resources science. In the New Era, natural resources research is facing various opportunities and challenges. This article discusses the nexus relationship between the frame of the Mountain-Water-Forests-Field-Lakes-Grasses, pointed out by President Xi Jinping, and the United Nations Sustainable Development Goals (SDGs) in terms of natural resources issues. It focuses on the four typical related research topics that are most concerned at home and abroad today, namely, resource-asset-capital nexus, energy-resource-technology nexus, food-water-energy nexus, energy-water-land-carbon emission nexus, combined with the policy guidance proposed in the New Era. It analyzed the geopolitical risks, climate change, international trade uncertainty, major emergency events and other issues and proposed several new perspectives and related suggestions which are aimed to provide some new ideas for the development of natural resources research and disciplines innovation capacity building. The authors believe that the century-long unprecedented changes have a profound impact on the status and role of natural resources. As a result, it is urgent to strengthen the basic theoretical research of natural resources and establish some major R&D plans for natural resources research as soon as possible to serve the national natural resources strategy and major engineering needs and provide some ways of important technological support for China.

    China's urbanization has started to rapidly encroach on the most valuable arable land resources and rural settlements, and it has therefore become extremely urgent to protect basic farmland, rural areas and agricultural space. However, for a brand-new round of territorial spatial planning at city and county level, with "the evaluation of resources and environmental carrying capacity and territorial spatial development suitability" which plays a fundamental role in spatial planning, emphasis is only placed on basic farmland and food production in agricultural areas. Therefore, the purpose of this paper is to optimize the theoretical and technical scheme of evaluation of "superior agricultural space", in order to serve as a foundation for protecting agricultural space, all agricultural producers and large rural areas. The technical methods employed in this paper are as follows. (1) A total-region and total-factor evaluation of suitability for farming, animal husbandry and fishery production is conducted outside the area of vital importance for ecological protection and the area of the ecological red line, dividing the space into "suitable regions for agricultural production" and "unsuitable regions for agricultural production". (2) Based on the evaluation principles of high stability, large-scale management and land connectivity, a TOPSIS model is constructed in order to further evaluate and demarcate suitable regions for producing grain and other important agricultural products and for producing special local agricultural products. (3) Based on the aforementioned points, superior agricultural space is identified by a multi-factor comprehensive evaluation procedure, taking characteristic and important rural areas and large agricultural infrastructure into consideration. The two cases in Shenyang and Wenzhou are adopted as examples for the study in order to demonstrate the validity, feasibility and practicability of our method. It is also proven that the evaluation and delineation of the superior agricultural space can assist the development and protection of territorial space at city and county level.

    Urban-rural integration is not only the transformation process of social and economic structure, but also the shaping process of urban-rural transitional development, that is to say, urban-rural integration can provide dynamics for urban and rural transitional development, and urban-rural transitional development is the physical performance of urban-rural integration. This paper takes Huaihai Economic Zone (HEZ) as the study area to analyze the difficulties faced by urban-rural integration development, to investigate the status of urban-rural integration development with multi-dimensional quantitative measurement, and lastly to put forward the measures of promoting urban-rural integration development. The results are as follows: (1) The urban-rural integration in HEZ is facing the predicament of 'three deficiencies' caused by the 'two separations and one shear effect', that is, the separation of 'settlements and agriculture' in traditional agricultural areas, the separation of 'production and living' in resource-based cities, and the 'shear effect' in provincial border areas. These deficiencies lead to the insufficient internal dynamics for rural transformation, insufficient power for urban radiation to rural areas, and insufficient regional synergy among different provinces on urban-rural public service supply, respectively. (2) The state of urban-rural transformation in HEZ has the characteristics of multidimensional correlation of various driving factors, asynchronous urban-rural development speed and heterogeneity and disequilibrium in spatial pattern. Through comparison and cluster analysis, urban-rural transformation in HEZ can be classified into four types: urban-rural transformation lag, rural transformation lag, urban transformation lag and urban-rural transformation synchronization. Its spatial distribution has distinct provincial agglomeration characteristics, verifying that the correlation between urban transformation and rural transformation in HEZ is not strong, its coordination is also not enough, and it has the 'shear effect' among provinces. (3) The key measures of promoting the urban-rural transitional development of HEZ from urban-rural integration perspective lie in breaking through the predicament of 'dual structure' in urban-rural areas and the 'fragmentation' of regional development, enhancing the coordinated transformation and development of urban-rural areas by differentiated policies, and strengthening the cross-domain collaboration of urban-rural development in provincial border areas.

    Rural-urban integration is an inevitable trend of the development of rural-urban relations. Studies on urban-rural integration are the requirement for giving play to the comprehensive advantages of geography in order to serve the national strategy. This paper took Huaihai Economic Zone as the research object, constructed multi-dimensional index system, and measured the level of urban-rural integration. The characteristics of spatio-temporal evolution and its driving mechanism were also discussed. Some conclusions were drawn as follows. The difference of urban-rural integration level among cities in Huaihai Economic Zone was relatively small. The level of urban and rural integration showed the characteristics of agglomeration in space. For most cities, local spatial structure of urban-rural integration was more dynamic, and its fluctuation was relatively small. Spatial pattern evolution showed the characteristics of strong integration. Factors of the city itself had more influence on the change of spatial structure of urban-rural integration. It was less affected by the spillover effect of the level of urban-rural integration in neighboring cities. The change of urban-rural integration in the cities was driven by economic development and urbanization. The change of urban-rural integration in the cities, which was at low level, was restrained by urban employment and government action. The change of urban-rural integration in the cities, which was at high level, was restrained by industry and government action. Finally, different countermeasures and suggestions were put forward for different types of cities.

    To restructure the evaluation index system of urban and rural integration from population, space, economy, society and ecological environment, the dynamic coupling coordination model was selected to measure the urban and rural multi-dimensional integration level, and the global Moran index and the local indicators of spatial association (LISA) were used to reveal the spatial distribution characteristics of the urban-rural multi-dimensional integration level in Huaihai Economic Zone. And then, the spatial correlation pattern in the study area was analyzed by the spatial structure index (SSI) from the population flow, logistics flow, capital flow and information flow. And finally, the driving mechanisms of urban-rural integration in the study area were explored by the fixed effect spatial error model (SEM-FE) from the perspective of these four types of flow. The results are as follows: (1) The urban-rural multi-dimensional integration levels are low but go well, the overall level in the research area rose from 0.016 in 2003 to 0.028 in 2017, with an annual rate of 0.08%. When the urban-rural multidimensional integration structure maintains stable in the research period, the economic integration is the highest, while the spatial integration is the lowest. (2) The regional interrelation is close in the context of population flow and capital flow, while it shows a "core-periphery" structure under the material flow and information flow. In general, the spatial structure in Huaihai Economic Zone is a decentralized network with multiple central cities, which lays a good foundation for the future development of urban-rural integration and inter-regional coordinated development. (3) In order to achieve the improvement of quantity and quality of urban-rural integration in Huaihai Economic Zone, we should shift the effect of the core area from agglomeration to diffusion, and need reasonable labor distribution and trading to stimulate the regional comparative advantage fully of each city node. Moreover, it is necessary to assist a series of cultural, economic and political systems in the implementation of local and national policies, because urban and rural integration development is a big cycle system of the socio-economy.

    Urban-rural integration development is the key initiative to solve the problems of excessive income gap between urban and rural areas and unbalanced and uncoordinated urban-rural development, and it is also the inevitable requirement of rural revitalization. This paper discusses the connotation of urban-rural integration development, and constructs an evaluation index system of urban-rural integration development by entropy weight method. Based on these, it reveals the characteristics of the factor pattern of urban-rural integration development in Huaihai Economic Zone in combination of the methods of landscape analysis, spatial analysis and coupling coordination analysis, and explores the influence mechanism of urban-rural integration development combined with regression model, in order to provide a theoretical reference for the urban-rural integration development in the border areas of underdeveloped provinces. The results are as follows: (1) Urban-rural integration is the process of rebuilding urban-rural relationship. The comprehensive level of urban-rural integration development can be described from the connectivity of urban-rural space, the convenience of urban-rural transportation, the balance of urban-rural public services and the livability of urban-rural ecological environment. (2) There are great differences in the indicators of urban-rural integration development in Huaihai Economic Zone. The comprehensive level index decreases from the center to the periphery. According to the spatial correlation and index coordination, Huaihai Economic Zone can be divided into three types: coordinated development region, associated development region and divided development region. (3) The level of economic development, the scale of urban-rural areas, and the industrial linkage are the key dynamic factors affecting the urban-rural integration development. However, the development of traditional agriculture and industry, as well as the urban-rural population structure, have no significant effect on regional urban-rural integration development. The theoretical and empirical research on urban-rural integration development at the scales of town and village is an important direction of follow-up work.

    The connotation of cultivated land use transition is deeply interpreted, and the relevant evaluation index system is constructed based on the systematic logic of rural revitalization and cultivated land use transition. This paper uses the methods of exploratory spatial data analysis (ESDA) and standard deviation ellipse (SDE) to evaluate the effectiveness of cultivated land use transition in 2002, 2007, 2012 and 2017 of Huaihai Economic Zone, so as to reveal the spatial-temporal pattern and path of cultivated land use transition under the background of rural revitalization. The results indicated that: (1) The cultivated land use transition showed a spatial-temporal pattern of overall rise and regional equilibrium during the past 15 years in the study area. (2) The spatial agglomeration of cultivated land use transition is obvious, and the difference between north and south is significant. The agglomeration degree of spatial transition is gradually weakened, and the functional transition shows a trend of decreasing first, then increasing, again decreasing and fainally tends to be stable. (3) The cultivated land use transition presents a northeast-southwest pattern, with Xuzhou as the regional center of gravity, which continuously shrinks in the north-south direction and shifts in the east-west direction, resulting in a C-shaped distribution of transition spatial form; the exchange coupling of system elements gradually increases and the ascending channel has a shrinking trend, and finally forms a transition path of "dispersion-gathering-dispersion-gathering". It is suggested that the future development of the study area should focus on the coordination and integration of the internal driving forces of transformation and development, and guide the cultivated land use transition from "C-shaped" diffusion to "O-shaped" internal collection, a circle inclusive growth pattern, and constantly improve the sharing degree of multi-functional integration benefits of cultivated land, and transform the balance mechanism of geographical system into the practical efficiency of rural revitalization.

    Nowadays, rural development that determines the progress of building the moderately prosperous society is the most concerned work of Chinese governments, and several national strategies and policies like rural revitalization and urban-rural integrated development were proposed to promote the rural development. The key of rural revitalization strategy implementation is to realize urban-rural cooperation by their mutual supports, and thus it is urgent to shed light on the dynamic mechanism of rural development oriented urban-rural integration. This paper first established a conceptual framework of dynamic mechanism of rural development oriented urban-rural integration, and then the structural equation model (SEM) including 5 latent variables and 16 observation variables was applied to validate this dynamic mechanism based on data of 120 towns in Xuzhou city of 2018. Lastly, corresponding policy implications for rural development in China were proposed. It was found that: urban-rural integration could be classified into urban-rural homogeneous integration and complementary integration, and the homogeneous integration implied that rural areas pursued the same conditions and treatments as cities, and the complementary integration referred that in the urban-rural competition, rural advantages should be created from the opposite perspective of urban areas, like leisure activities, ecological tourism and healthy development. Urban-rural homogeneous integration was the external driving force of rural development, while urban-rural complementary integration was the internal driving force. External driving force included two aspects of urban-rural infrastructure and public service integration, and they impacted rural development indirectly with corresponding effect of 0.1558 and 0.6836, respectively; internal driving force also included two aspects of rural attraction and rural factors conglomeration, and they impacted rural development directly with corresponding effect of 0.702 and 0.3356, respectively. The urban-rural infrastructure integration firstly improved conglomeration level of rural factors like capital, land and labor, and then promoted rural development; similarly, urban-rural public service integration firstly improved rural attraction, and then made countryside developed. In terms of policy implications, multidimensional rural development dynamics should be established from the views of urban-rural homogeneous integration and complementary integration, and external driving force should be mainly created by government investment, while internal driving force was created and shaped by rural planning. Governance boundaries among market, government and society (locality) with respect to the creation of rural development dynamics should be defined. Rural revitalization should follow the law of rural life cycle and delimit its geographic space according to different rural types. This study reveals rural development dynamics mechanism from a perspective of urban-rural integrated development, which has an importance guidance for governments to implement rural revitalization strategy at the operational level.

    Sustainable development and construction are the goal and vision of rural revitalization, the focus of promoting the integration of urban-rural development and building a sustainable urban-rural integration system. Under the background of the increasing urbanization process, it is necessary to define the stage and state of rural development, measure the development potential, and effectively identify the future development direction and mode of rural areas, and achieve the goal of rural sustainable development and construction. This paper chooses the Northern Jiangsu province as the research object, and 7980 administrative villages located in Huaihai Economic Zone as the evaluation units to study the rural development status of the village area units. Through the county scale constraints on the urban and rural development stage, the comprehensive measurement of the rural development potential is carried out with the idea of "differentiation and consistency". The results show that: (1) The rural areas in the study area can be divided into three development stages: urban leading, urban-rural linkage and rural leading, with the proportion of 15.38%, 46.15% and 38.46%, respectively. (2) The maximum and average values of the rural development status index in the study area are 6.209 and 1.714, characterized by high value area and low value area agglomeration, respectively. (3) The maximum and average values of rural development potential in the study area are 2.827 and 0.923, respectively, and the proportions of evaluation units are 4.45%, 15.20%, 23.22%, 35.39% and 21.74% with the potential grades from low to high. (4) According to the rural development potential, this study area can be divided into four categories: "key potential area", "balanced potential area", "moderate potential area" and "important maintenance area". This paper puts forward the development ideas of "Narrow the gap within the region by stimulating recessive vitality", "Achieve regional balanced development driven by advantage elements", "Find out disadvantage conditions and fill the potential space moderately" and "Maintain the present mode to achieve stable development".

    Rural dilution is the process of the evolution of structural contradictions between rural multidimensional spaces and their elements in the process of urbanization, a presentation of rural space issue in the unbalance of urban and rural relationship, and an important project of rural geography in the new era. Based on the urban and rural perspective, the paper analyzes the concept and connotation of rural dilution, and measures the process and state of rural dilution in Northern Anhui Area from population vitality, land use and social activity, explores the temporal and spatial characteristics, influencing factors and forming mechanism with the methods of spatial autocorrelation, geographical weighting regression, and geographical detector. The results show that: (1) In recent 10 years, the rural dilution in this area has been characterized with phased acceleration process. (2) Water resources quantity per capita, farming population density, poverty incidence, diversity factors of income of urban and rural residents, number of pupils at school in the rural unit, number of doctors in rural resident clinic per ten thousand persons exert remarkable influence on the rural dilution in the study area. (3) In the special context of urban and rural relationship, the combined action of urban system control and guidance, and rural system passive response promote the formation and extension of rural dilution. The study provides reference for the research of rural transfer and integrated urban and rural development and theoretical guidance for the precise implementation of rural revitalization and rural planning. The paper emphasizes scientific recognition, timely solutions to rural dilution, and further theoretical research and practice exploration of rural transformation and urban and rural integration. How to deal with rural dilution and lead the sharp contraction of rural space, and how to achieve integrated urban and rural development from the perspective of restructuring the space of production, life and ecology are the orientation for the next research stage. Scientific recognition of rural dilution can provide theoretical guidance for targeted tactics of rural revitalization and urban and rural integration development.

    Urban-rural green development efficiency is of great significance to the construction of efficient and low consumption green development model, the sustainable development of social economy and the realization of urban-rural integration. Based on 13-year panel data of 35 counties in Lunan Economic Belt (also known as Southern Shandong Economic Belt), the article estimated the spatio-temporal differentiation characteristics and driving factors of urban-rural green development efficiency in the study area by using DEA-Malmquist index method, decoupling state model of urban-rural green development efficiency, geographic detector and other econometric models. Research shows that: (1) Technological progress is the main source of green TFP growth, but its contribution is declining, while the pure technical efficiency and scale efficiency to green TFP growth is increasing year by year. (2) The growth of green TFP has spatial differentiation, and the high and sub-high efficiency areas of green TFP are different during the research period. The growth tends to concentrate in the northeast and southwest of Shandong province. (3) The decoupling relationship between urban and rural green development efficiency in the study area appears repeatedly, from negative decoupling (coupling) to decoupling and then to negative decoupling. On the whole, the green development of urban and rural areas is in the stage of dynamic change and non-coordination (or low-level coupling). (4) The number of students in ordinary middle schools, grain production and savings deposit balance of urban-rural residents are the driving indexes of urban-rural green development efficiency. The explanatory power of factor interaction on the urban and rural green development efficiency is far greater than that of single factor, reflecting the complexity of the driving factors of urban-rural green development efficiency in the Lunan Economic Belt.

    The identification of ecological source in the traditional ecological network construction mostly considers the quality and area of habitat patches, but seldom considers the impact of ecosystem service function and spatial structure. Moreover, the traditional ecological network is mostly constructed in a relatively closed unit with only one scale, lacking nesting coordination, which will lead to the dislocation of ecological network structure between scales. To solve the above problems, an "Attribution-Function-Structure" index system is constructed to identify the ecological sources comprehensively. The Least-cost path method, the Circuit Theory and the Cyclic Window Search Method are adopted to form and identify ecological corridors, pinch points and barrier points respectively. From the Xuzhou metropolitan area and main urban area, two-scale ecological networks are constructed and overlapped to analyze its nested structure and coordination degree. The results showed that: (1) The coincident source areas at two scales is 79.85 km², the overlapping corridors length is 158.42 km, and overlapping corridors area is 45.68 km², which are important for the stability of the multi-scale ecological network connection and need to be protected. Meanwhile, 8 corridors that are vital to the metropolitan area but lack the underbelly support within the main urban area should be repaired as a priority. (2) A total of 17 and 18 pinch points are identified in the metropolitan area and the main urban area respectively, 10 of which overlapped; 8 and 10 barrier points are identified respectively as well, 5 of which overlapped. Contact ratio indicates that high migration resistance and large optimization potential coexist in key biological migration areas, which is in urgent need of repair. And the continuity of biological processes across scales need a multi-scale cascade framework to solve ecological problems coordinately. (3) Based on the theory of "Patch-Corridor-Matrix", a multi-scale nested ecological network optimization strategy is proposed from the three points about "Point-Line-Polygon". The research results can provide references for the regional ecological security pattern construction, land consolidation and ecosystem restoration.

    Industrialization and urbanization have intensified the development transition and spatial restructuring of rural areas, which leads to the problems of urban-rural uncoordinated development and inadequate rural development. The "rural revitalization" strategy proposed by the 19th National Congress of the CPC in 2017 became the starting point of high-quality agricultural and rural development. As an advanced form of rural residents and settlements integrated development, the symbiotic degree of housing and industrial land can well reflect the quality and effect of rural revitalization. In this paper, Xuzhou, the central city of Huaihai Economic Zone, is selected as a case study. Land use data are used to explore the spatial symbiotic degree of residential and industrial land. From two dimensions of structure and function, this paper explores the symbiotic pattern of housing-industry in three spatial scales, namely district/county, town and village. The results show that: (1) The land supply of Xuzhou shows the imbalance of housing-industry. Housing space is more dominant than industrial space. Due to the current vacant land or abandoned land, the residential and industrial lands in use are more symbiotic. We propose to explore ways to allow the conversion of housing land into commercial land to increase the rural industrial space. At the same time, the government should guide the industrial development and revitalize the industrial spaces around central towns to improve the utilization efficiency of rural land. (2) The state of the symbiotic degrees at the three spatial scales has differences. The relationship between residential and industrial space at township scale is relatively stable and basically maintains in a relatively balanced state. It is concluded that township is the best scale for allocating land resources and implementing rural revitalization strategy. Villages exercise their own functions so that all of the villages form an organic combination at township level. Then, they will achieve the state of symbiosis. (3) In the following studies, the appropriate ratio of housing-industry land and the impact of agricultural land on housing-industry symbiosis need further exploration and analysis.

    Using the ratio and GIS spatial analysis methods, this paper analyzes villagers' living space characteristics and their relocating willingness. All the data were obtained from the full sample survey from October to November 2018 on the 15510 natural villages and 872414 rural households in Huai'an. There are some findings as follows: (1) The rural settlements are not only scattered but also smaller on average. And what's more, there are some villages only with one family in Huai'an. Besides, most of villages are far away from the town, and nearly half of them are in the certain location which is near the water sources, or road, or railway, or situated in flood detention area, etc. These spatial characteristics are the results of a combination of the physical geographical conditions and human factors, such as the agricultural production around rural houses. (2) For the farmer's house, the proportion of the old house is higher, and 40% of rural households have their houses in both towns and villages. There is a negative correlation between the ratio of rural households which have urban houses and the distance from the village to the town center. However, the ratio of rural vacant house presents the opposite spatial pattern. (3) For villagers' willingness, 54.1% of rural households are willing to be relocated in a centralized way and most of them prefer compensation in kind. The main reasons for farmers' unwillingness to be relocated in a centralized way includes the lower compensation standards and the inconvenient farming conditions. The main destination of farmers who are willing to be settled in cash is the city, while staying in villages or in towns is other farmers' option. Nearly 90% of the farmers with willingness to relocation will choose the resettlement house which would be built by the local governments, and nearly 80% of them would return the homestead or transfer the contracted land with compensation. (4) There are obvious spatial differences in both the characteristics of villagers' living space and their willingness to relocation, which are internally related and affected by various factors.
