长江经济带矿产——经济——生态环境系统耦合协调发展研究

Research on the Coupling and Coordinated Development of Mineral-Economy-Ecological EnvironmentSystem in the Yangtze River Economic Belt

为贯彻落实“共抓大保护,不搞大开发”的建设思想理念,实现长江经济带绿色可持续发展,基于2001—2019年长江经济带11省市的相关数据,构建了矿产资源—区域经济—生态环境评价体系。通过设定三大子系统的优先发展级,运用熵权法、耦合协调度模型定量分析不同优先级下的矿产资源—区域经济—生态环境系统耦合协调发展水平,并从中选取最优发展模式。结果表明:长江经济带三系统耦合协调发展特征显著,整体上由轻度失调区间上升至中级协调区间,且耦合协调度值上游<中游<下游。分省来看,耦合协调程度由低到高依次为云南、江西、贵州、安徽、湖南、上海、重庆、江苏、四川、浙江、湖北。除了湖北、浙江、四川三省位于良好协调区间外,其余8省市均位于中级协调区间。同时,“经济优先”仅适用于短期发展,“环境优先”更适合长期发展。故为促进长江经济带协调可持续发展,整体上应坚持以环境保护为重心的发展战略,个体上要进一步针对不同省市采取差异化的措施。

To implement the ideological concept of steppe up conservation of the Yangtze River and stop its over develop-ment,and realize the green and sustainable development of the Yangtze River Economic Belt,based on the relevant data of 11 provinces and cities in the Yangtze River Economic Belt from 2001 to 2019,a mineral resources-regional economy-ecological environment evaluation system was established.By setting different priorities of the three subsystems,the entropy weight method and the coupling coordination degree model are used to quantitatively analyze the coupling and coordinated development level of the mineral resources-regional economy-ecological environment system under different priorities and select the optimal devel-opment mode.The results show that:the coupling and coordinated development of the three systems in the Yangtze River Eco-nomic Belt are remarkable,which generally arise from the mild maladjustment interval to the intermediate coordination interval,and the coupling coordination degree value is upstream<midstream<downstream.In terms of provinces,the degree of cou-pling coordination from low to high is Yunnan,Jiangxi,Guizhou,Anhui,Hunan,Shanghai,Chongqing,Jiangsu,Sichuan,Zhe-jiang,and Hubei.Except for Hubei,Zhejiang and Sichuan,which are located in the good coordination range,the other eight provinces and cities are located in the intermediate coordination range.Simultaneously,economic priority is only suitable for short-term development,and environmental priority is more suitable for long-term development.Therefore,in order to promote the coordinated and sustainable development of the Yangtze River Economic Belt,the development strategy focusing on environ-mental protection should be adhered to as a whole,and differentiated measures should be further taken for different provinces and cities.
