黄河流域资源型城市水资源-能源-环境-经济耦合分析OA

It is significant to study the coupling coordination development relationship of water,energy,environment and economy(WEEE)system of resource-based cities in the Yellow River Basin to achieve ecological protection and high-quality development in the Yellow River Basin.This study developed a water-energy-environment-economy evaluation indicator system.Based on the data of 33 resource-based cities in the Yellow River Basin from 2002 to 2022,this paper used the coupling coordination model to analyze the temporal evolution and spatial dis-tribution characteristics of coupling coordination,used the spatial autocorrelation model to analyze the clustering differences of coupling coor-dination,and further used the obstacle degree model to diagnose the obstacle factors restricting the development of coupling coordination.The results show that:a)The overall coupling coordination value of the Yellow River Basin shows a fluctuating upward trend,the overall coordi-nated development level of WEEE gradually increases,and the coupling coordination degree shows a pattern of the overall mean value of the downstream＞upstream＞overall mean＞midstream.b)The spatial distribution of coupling coordination showed a spatial variation pattern of high in the periphery and low in the middle,and the Moran index increased from 0.18 to 0.34 from 2002 to 2022,showing a certain spatial ag-glomeration.c)The first obstacle factor in the Yellow River Basin is per capita water resources,and its obstacle degree is increasing.
