Research on land space optimization based on dual evaluation from the perspective of human-land relationship

In the process of China's rapid urbanization, the accumulation of social wealth is also accompanied by huge conflicts between people and land and the problem crisis, which is reflected in the contradiction between the rapidly growing consumption demand of human beings and the limited natural resources and environment. As an important tool to identify resource and environmental weaknesses and construction and development risks in the development and utilization of territorial space, the "double assessment" (assessment on the carrying capacity of resources and environment and the suitability of territorial space development) provides a basic basis for supporting territorial space planning and implementing comprehensive territorial improvement projects. There is a relationship between scale support and function orientation between double evaluation, which reflects the interaction between natural environment and human social system. From the perspective of human-land relations, this paper expounds the optimization of city-county land spatial pattern based on double evaluation in terms of the pressure intensity of human activities, the supporting capacity of resource elements, and the constraint correction degree of ecological environment. To explore the dialectical relationship between the natural environment and human social and economic activities behind the double evaluation, and to discuss how to scientifically and rationally connect the integrated results of the "double evaluation" with the optimization plan of the national spatial pattern. In honghe prefecture of yunnan province as a case, the reasonable requirements of human production and living into land demand parameters, combined with multiple stakeholders of negotiations, focusing on the adjacent regional conflicts and coordination function, major disaster prevention engineering, state domain perfect traffic network pattern characteristics and regional development strategy, constantly checking and optimization, to enhance robustness optimization results, for national spatial optimization and provide material basis and guarantee for sustainable economic and social development.
