洞庭湖区生态—经济—社会系统耦合协调发展的时空分异

The Evaluation of Coulpling Coordination Development of Ecology-Economy-Society System in Dongting Lake Area

构建了洞庭湖区生态—经济—社会复合系统协调发展的评价指标体系,引入耦合度和耦合协调度函数,测算了2000—2013年洞庭湖区的耦合度、协调度和综合发展值,并对测算结果进行了对比分析。结果表明:1从时序的动态演变上看,2000—2004年洞庭湖区生态—经济—社会系统的耦合协调发展状态为中度失调,2005年开始转入基本协调,2009年实现中度协调。2从空间分布上来看,岳阳于2008年最早实现中度协调状态,常德和益阳则分别于2009年、2010年达到中度协调。虽然近14年来洞庭湖区生态—经济—社会系统的耦合协调发展水平不断提高,但离高度协调状态仍然存在一定差距,经济社会子系统和生态子系统之间的矛盾是制约整体协调发展水平的主要原因。

This paper constructs the evaluation index system of harmonious development of ecology-economy-society system in Dongting Lake area, by employing the coupling degree model and theeoupling coordination function, calculated the degree of the comprehensive development in Dongting Lake area from 2000 to 2013. According to the calculation and comparation of result, it shows that： 1）From the dynamic evolution of timing point of view, the state of coordinated development of ecology-economy-society system in Dongting Lake area is moderate disorders from 2000 to 2004, then transfered to basic coordination in 2005, and achieved moderate coordination in 2009. 2）Judging from the view of spatial distribution, Yueyang achieved moderate coordination state in 2008, Changde and Yiyang achieved respectively in 2009 and 2010. Although the level of harmonious development of ecology-economy-society system in Dongting Lake area increases in past few years, but it still has a long way to go. The main reason that restricts the overall level of coordinated development：The contradiction between the development of ecology, economy and society economy is the main constraints in Dongting Lake area.
