| With the rapid development of China’s economy,environmental problems are emerging day by day.As an important organizational form to promote economic development,industrial agglomeration has also brought crowding effects and large-scale pollutant emissions,which have a certain impact on the environment.As the economic support belt of China,the Yangtze River Economic Belt plays an exemplary and driving role in the construction of China’s ecological civilization,How to balance the coordinated development of industrial agglomeration and ecological environment has important practical significance.On the basis of collecting and sorting out relevant literature,this study first defines the relevant concepts of industrial agglomeration and ecological environment,explores the interaction between the two systems,combs the status quo of manufacturing industry and ecological environment by referring to the relevant research of domestic and foreign scholars,and measures the level of manufacturing industry agglomeration by using location entropy and EG index;By constructing the comprehensive evaluation index system of industrial agglomeration and ecological environment in the Yangtze River Economic Belt,the weight of each index is calculated;On this basis,calculate the comprehensive development index of the two systems;The coupling coordination degree model is used to analyze the coupling coordination degree of industrial agglomeration and ecological environment in the Yangtze River Economic Belt from 2015 to 2020,and the Arc Map10.5 and Geo Da software are used to visually describe the spatial evolution characteristics and spatial correlation of the coupling coordination degree of the two systems;The influencing factors of the coordination degree of each region were evaluated by using the grey relational model;Finally,using the gray prediction model and MATLAB software to predict the coupling and coordinated development trend of the two systems of the Yangtze River Economic Belt in the next five years.The results show that:(1)The concentration level of manufacturing industry in the Yangtze River Economic Belt is gradually decreasing in the lower,middle and upper reaches.(2)From 2015 to 2020,the average coupling coordination degree of the Yangtze River Economic Belt was in the primary coordination stage,and the coupling coordination degree of industrial agglomeration and ecological environment in the lower reaches was far higher than that in the middle and upper reaches.(3)From the perspective of space,the spatial pattern of the overall coupling and coordination degree of the Yangtze River Economic Belt generally shows the spatial characteristics of "high in the east and low in the west",and there is a large gap in the coordination degree between regions.(4)The overall Moran’s I of the coordination degree of industrial agglomeration and ecological environment coupling in the Yangtze River Economic Belt is positive,with obvious positive spatial correlation.The local spatial characteristics show a trend of polarization.At the same time,it can be seen that the provinces in the "low low" spatial agglomeration are mainly concentrated in the western region,and the "high high" agglomeration is concentrated in the Yangtze River Delta region.The spatial correlation of the coordination degree between the two systems of the Yangtze River Economic Belt and the regions with high concentration degree are relatively stable.(5)From the perspective of influencing factors,the influencing factors of coupling coordination degree in different regions are obviously different.On the whole,the discharge of industrial three wastes is an important factor affecting the coupling coordination degree of the two systems.(6)It can be seen from the predicted trend that the coupling coordination of Shanghai,Anhui,Chongqing and Guizhou in the Yangtze River Economic Belt will show a downward trend from 2021 to 2025,while that of other provinces will show an increasing trend.Figure [21] Table [19] Reference [134]... |
