Research on coupling coordination and spatial differentiation of new-type urbanization and ecological environment in Wanjiang demonstration area

Abstract

This study discussed the interaction mechanism of new-type urbanization and ecological environment, and then relevant data of the nine cities in Wanjiang Demonstration Area in 2016 was gotten. With the entropy weight method, the coupling coordination degree model and the exploratory spatial data analysis method, the coupling coordination degree and spatial agglomeration characteristics of new-type urbanization and ecological environment in Wanjiang Demonstration Area were analyzed. The results show that: Firstly, the comprehensive development index of the new-type urbanization and the ecological environment shows obvious positive correlation, and it appears a higher internal consistency through the whole development stage. The coupling degree of the nine cities is in a relatively balanced situation, Hefei and Ma'anshan are in the high level coupling stage, Xuancheng is in the antagonistic stage, and the other six cities are all in the stage of grinding. Secondly, the coupling coordination degree of new-type urbanization and ecological environment shows a weak positive correlation in space, and the degree of spatial agglomeration is not very significant. Except for Hefei with the over harmonization condition, the other eight cities are in the situation of maladjustment. Thirdly, according to the spatial agglomeration analysis, the local spatial autocorrelation of the coupling coordination degree is obvious. Although the different agglomeration regions show some expansion or contraction in the spatial evolution, cities with high degree of coupling coordination are clustered, while cities with low degree of coupling coordination are dispersed.
