Research on the Coupling and Coordinated Development of Energy,Economy and Ecological Environment in Anhui Province
To promote the mutual integration and coordinated development of energy,economy and ecological environment,the improved entropy method is used to calculate the comprehensive development level of the energy economy ecological environment system of 16 prefecture level cities in Anhui Province from 2016 to 2020,and the coupling coordination model is used to evaluate the coordinated development level of each system.It is concluded that the comprehensive development level of the three major systems from 2016 to 2020 is ecological environment system＞economic system＞energy system,and the coupling coordination degree of the three major systems is in a"rising-declining"state,among which the coordination degree of economy and ecological environment is the highest.From the perspective of the evolution pattern,the coordinated development of energy and economy shows a pattern of"Northern Anhui＞Southern Anhui",in which the southern region of Anhui province develops in a"U-shaped"pattern;the coordinated development of economy and ecological environment.Shows that cites in central Anhui Province are lower than their neighbouring cities,and the cites with high coupling degree gradually spread from southern Anhui Province to nroth.The coupling and coordinated development of energy and ecological environment presents a pattern of"Northern Anhui＞Central Anhui＞Southern Anhui",and the Northern Anhui shows a fluctuating upward trend.
