Research on quantitative evaluation method of carrying capacity based on coordination degree of geological environment-socioeconomic complex system

From the point of restriction and safety, the evaluation index system of geological environment carrying capacity is constructed in this paper. On this basis, the carrying capacity is combined with the GDP and population of social economic system. By introducing system coordination concept, we build a quantitative expression model of spatial coordination degree and overall coordination degree. Then a method is proposed to express the carrying capacity of geological environment by using the evaluation results of the coordination degree of the geological environment and socio-economic composite system. The research results can effectively present the carrying state between the background and the load-bearing object in the spatial layout. At the same time, the research ideas can be used for carrying capacity evaluation of other relevant elements of the resources and environment, and can also support the study of the development, utilization and protection of the geological environment, the demarcation of the red line for environmental protection, the evaluation of regional development status and the layout rationality, the preparation of regional development planning, and the evaluation of the performance of ecological civilization construction.
