In the new era, the core goal of territorial spatial planning is to meet the people's needs for a better life and also to protect natural resources. As a new type of planning, the method of territorial spatial planning is generally lacking. Based on the endowment of natural resources, scholars use data based on statistics and surveys, as well as methods of statistical analysis, spatial analysis and deduction to evaluate the carrying capacity and suitability of land space at the national and provincial levels, and make a static delimitation of the ecological red line, prime farmland protection line and urban development boundary. However, the existing studies rarely consider the dynamic impact of human activities on the use of land space, and lack the scientific arrangement of ecological space, agricultural space and urban space under the new development trend. This paper introduces the big data which can directly reflect the temporal and spatial changes of human activities. It mainly discusses the direction and specific methodological framework of the application of big data from the four parts of territorial spatial suitability evaluation, ecological spatial planning, agricultural spatial planning and urban spatial planning. Meanwhile, it emphasizes the scientific path of territorial spatial planning compilation under the interaction of "natural space" and "social and economic activities".

At present, China is promoting the modernization of territorial space governance, and the territorial space planning system is also being reconstructed. As a response, the spatial planning of metropolitan area is facing the transformation of political logic oriented by ecological civilization and development logic constrained by resources and environment. Based on the transformation of planning logics, the paper clarifies that the spatial planning of metropolitan area is a special planning with the focus on coordinated development of space as the core in the system of territorial space planning, and puts forward the technical framework of the spatial planning of metropolitan area from the two perspectives, namely, corresponding demand objectives and coordination of local conditions. Based on the above new requirements, the paper considers that the planning should focus on the formulation of conduction and coordination-oriented index system, the optimal allocation and regulation of liquidity factor resources, the planning of spatial pattern of coordinated control and utilization, and the spatial cooperation of cross-border groups. In view of the lack of a unified implementation subject, this paper puts forward the organizational mode of spatial planning compilation in different types of metropolitan areas. Regional cooperation mechanism, dynamic monitoring of the plan, and co-construction of information platform for management, are also proposed. Through the systematic discussion on the spatial planning of metropolitan area, this paper will provide theoretical basis and methodological guidance for the compilation of the forthcoming spatial planning and the modernization of the spatial governance of metropolitan area.

Ecological-production-living space (EPLS) is not only the basic carrier of human economic and social activities, but also the spatial reflection of human spiritual and cultural needs. Identifying the scope, understanding residents' demand, adjusting the supply and coordinating the functions of EPLS, are the core of the content of the territorial space planning, as well as the important premise of realizing the modernization of governance capacity and high-quality development in the new era. Based on the requirement of compiling the current territorial spatial planning, and the theoretical methods of behavioral science and behavioral geography, this paper explores the theoretical relationship between ecological-production-living behavior and ecological-production-living space. According to the principle of "demand analysis and spatial identification-problem diagnosis and goal determination-mechanism and coupling relationship-spatial optimization and policy suggestions", an optimization analysis framework of EPLS based on residents' behavior is constructed. This study combines residents' behavior research with space supply and demand, and provides a theoretical framework and new ideas of "humanization" for land and space planning.

The resource and environment carrying capacity is the basis for strategy decision-making of regional development, especially the optimization of spatial development strategy. In recent years, it has played a pivotal role in guiding regional sustainable development, land planning, urbanization, post-disaster reconstruction planning, and industrial planning. At the same time, clarifying the interaction mechanism between regional resource-environment and production-living factors is the basis of the evaluation of resource and environment carrying capacity. Based on PSR model, this paper presents the conjugation-wrestling theoretical mechanism of resources-environment and production-living, which divides the carrying capacity into four pairs of interaction forces, i.e., support-sensitive point, recovery-fragile point, destruction-critical point and development-equilibrium point. Then it presents DENS model including four dimensions, namely development, environment and disaster, natural resource and ecology, and social welfare.
