沿长江城市生态环境与经济协调发展研究

Study on Coordinated Development of Ecological Environment and Economy of Cities along the Yangtze River

文章选取2007—2016年长江中下游沿江八市作为研究对象,运用熵值法确定权重,引入协调度和协调发展度模型,构建协调发展度评价指标体系并对其生态环境与经济协调的发展状况进行实证分析。研究结论:(1)长江中下游城市生态环境与经济质量大幅度提升,并且长江下游沿江城市的经济发展均优于中游城市,生态环境发展则相反;(2)长江中下游沿江城市的生态环境和经济协调发展在2012年之前基本处于失调状态,2012—2014年从低级向中级协调发展过渡,2014年之后长江下游城市处于良好、中级协调之间,长江中游城市均达到优质协调发展水平。

Based on entropy method for weight determination and introduced coordination degree and the coordinate developmental models, the evaluation index system of coordination degree is constructed by taking eight cities along the middle-lower Yangtze River from 2007 to 2016 as the research object. Then, the evaluation index system of coordination degree is used to empirically research the status of ecological environment and economy coordinated development. Research conclusions: Firstly, ecological environment and economic quality of cities along the middle-lower Yangtze River have been greatly improved, and economic development is that cities along the lower reaches of the Yangtze River are better than those along the middle reaches of the Yangtze River, while the development of ecological environment is the opposite. Secondly, coordinated development of ecological environment and economy of cities along the middle-lower Yangtze River is as follows: before 2012, it was basically out of balance;in 2012-2014, the transition from low-level to middle-level;after 2014, cities along the lower reaches of the Yangtze River are between good and general level, and cities along the middle reaches of the Yangtze River have reached a high quality level.
