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