东北三省城镇化与生态环境的耦合分析

Coupling Analysis of Urbanization and Ecological Environment in the Three Provinces of Northeast China

为了对东北三省城镇化与生态环境耦合协调发展水平进行综合测度,以2008-2016年东北三省22项统计指标的数据为基础,构建城镇化与生态环境耦合协调发展度模型,结合熵权法对东北三省城镇化与生态环境的综合发展水平和耦合变化趋势进行量化分析。研究结果显示:东北三省城镇化和生态环境的耦合度普遍较高,两系统之间存在较强的依赖关系;耦合协调度的时间序列呈上升趋势,并伴随着显著的地区差异;耦合协调类型随时间的推移发生明显的变化。

In order to comprehensively measure the coordinated development level of urbanization and the ecological environment in the three northeastern provinces in China.It builds a coupled development model of the urbanization and ecological environment based on the data of 22 statistical indicators in the three northeastern provinces from 2008 to 2016,combined with entropy weight method.The comprehensive development level and coupling trend of urbanization and ecological environment in the three northeastern provinces were quantitatively analyzed.The results show that:the first,the coupling degree between urbanization and the ecological environment in the three northeastern provinces is generally high,and there is a strong dependence between the two systems,the second,the time series of coupling coordination degree is on the rise,accompanied by significant regional difference.The third,the type of coupling coordination changes significantly over time.
