基于复合系统协调度的地质环境承载能力定量评价方法研究

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

从限制性与安全性角度出发,构建了地质环境承载能力评价指标体系。在此基础上,将承载能力与社会经济系统中人口与GDP这2个指标相结合,引入系统协调度概念,构建了空间协调度与整体协调度定量化表达模型,并首次提出利用地质环境-社会经济复合系统协调度评价结果来表达地质环境承载能力的方法。该研究成果能够在空间布局上有效呈现出承载本底与承载对象间的承载状态。同时,该研究思路可用于其他有关要素的资源环境承载能力评价工作中,亦可支撑地质环境开发利用与保护红线划定等领域的研究。

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.
