【摘要】：城镇化与资源环境承载力之间相互影响、相互制约,在建立评价指标体系的基础上,运用耦合度和耦合协调度模型,定量研究了1979—2014年中国城镇化与资源环境承载力耦合关系及其演变过程,得出的主要结论有:第一,伴随城镇化综合指数提高,中国资源环境承载力综合指数先下降、后上升,经历了"U"型变化过程;第二,中国城镇化与资源环境承载力耦合度一直处于拮抗阶段,既存在城镇化对资源环境承载力的胁迫效应,也存在资源环境承载力对城镇化的约束作用;第三,城镇化与资源环境承载力耦合协调度经历了中度失调、轻度失调和临界协调三个阶段。
[Abstract]:Urbanization and the carrying capacity of resources and environment influence each other and restrict each other. Based on the evaluation index system, coupling degree and coupling coordination degree model are used. This paper quantitatively studies the coupling relationship between urbanization and carrying capacity of resources and environment in China from 1979 to 2014 and its evolution process. The main conclusions are as follows: first, with the increase of comprehensive index of urbanization. The comprehensive index of the carrying capacity of resources and environment in China first decreased, then rose, and experienced a "U" type change process. Secondly, the coupling degree between urbanization and carrying capacity of resources and environment in China is always in an antagonistic stage. There exists both the stress effect of urbanization on the carrying capacity of resources and environment, and the binding effect of carrying capacity of resources and environment on urbanization. Third, the coupling coordination degree between urbanization and carrying capacity of resources and environment has experienced three stages: moderate imbalance, slight imbalance and critical coordination.
