Analysis of coupling coordination development between urbanization and geological hazards in Zhejiang Province
This research aims to study the intrinsic relationship between urbanization and geological hazards,so as to promote sustainable urban development.The TOPSIS method and the coupling coordination degree model were employed to examine the temporal and spatial changes in the urbanization and geological hazards,as well as the coupling coordination degree,in 11 cities in Zhejiang Province from 2010 to 2020.The results indicated:① The comprehensive level of urbanization in each city exhibited a continuous improvement trend throughout the period,and the gaps among the cities were narrowing.② Based on the observed trends,the comprehensive level of geological hazards in each city can be classified into four categories:fluctuating,intermediate fluctuating,gentle,and inverted"S"types.In the early stage,the comprehensive level of geological hazards in various cities was relatively low and the growth was slow.In 2017,all cities reached their highest recorded level,followed by a subsequent decline and eventual stabilization.③ The coupling coordination degree of most cities exhibited a positive correlation with temporal chan-ges,reaching its peak in 2017,and the disparities of coupling coordination degree diminished continuously.From 2010 to 2020,the development stage of the coupling coordination degree in Zhejiang Province was predominantly characterized by barely coordinated development,with the best spatial pattern observed in northern Zhejiang,followed by central Zhejiang,and the least favorable situ-ation in southwest Zhejiang.The outcomes of this research can serve as a valuable reference for urban development,as well as the prevention and control of geological hazards in Zhejiang Province.
