摘要
利用2009~2013年相关数据,在城市生态环境与农村生态环境耦合协调关系评价指标体系构建的基础上,运用熵权法确定指标权重,同时引入耦合度与耦合协调度模型,定量计算云南城市生态环境与农村生态环境的耦合度与耦合协调度,并结合耦合度阶段与协调度类型划分标准对两者间的耦合协调关系进行定量评价。研究表明：从综合指数看,云南城市生态环境综合指数波动较大,农村生态环境综合指数变化比较平稳,且城市生态环境综合指数增幅小于农村生态环境综合指数增幅;从耦合度看,云南出现由农村生态环境滞后向城市生态环境滞后的转变,城市生态环境与农村生态环境耦合度经历了从磨合阶段到高水平耦合阶段的变化,两系统间的发展方向越趋有序,关系越趋稳定;从协调度看,云南城市生态环境与农村生态环境协调度呈上升趋势,耦合协调类型从低度协调转变为中度协调并最终呈现良好协调的发展态势。
By using the relevant data of 2009 - 2013, based on the evaluation index system of the coupling coordination relationship between urban and rural ecological environment with the index weights determined by the entropy method, and the coupling degree model and coordination degree model, it was calculated quantitatively the coupling degree and coupling coordination degree between urban and rural ecological environment in Yunnan, combining with the classification standard of coupling stage and type of coordination degree for the quantitative evaluation of the coupling coordination relationship. The result shows that, from the point of the comprehensive index, the comprehensive index of urban ecological environment is more volatile, the comprehensive index of ecological environment in rural areas is relatively stable, and the growth rate of comprehensive index of urban ecological environment is less than the cornprehensive index of rural ecologi rural ecological environment has cal environment. From the point of the coupling degree, the backward development of been replaced by the backward of urban ecological environment in Yunnan Province. The coupling degree of urban ecological environment and rural ecological environment have changed from run - in phase to high level coupling stage, the development directions of the two systems are more orderly and more From the point of coordination degree, the coordination degrees of urban and rural ecological environment are coupling coordination type is changed from low degree of coordination to moderate coordination and finally the stable. rising, well - coordinated development trend.
