As a dense area of industrial development in Shanxi Province,Fenhe River basin is an important carrier of wastewater pollution while providing water resources for regional development.Studying the coupling coordination level of water resources and water pollution in the Fenhe River basin is of great significance for strengthening the utilization of water resources and water pollution control in the Fenhe River basin,and promoting the coordination of ecological protection and economic development in the basin.Based on the Fenhe River basin,the evaluation index system of water resources and water pollution in the Fenhe River basin was constructed.The coupling coordination model was used to analyze the coupling coordination level of water resources and water pollution in the Fenhe River basin from 2011 to 2021,and the GM(1,1)grey prediction model was used to explore the future development trend of coupling coordination.The results show that from 2011 to 2021,the coupling degree and coordination degree of water resources and water pollution system in Fenhe River basin show a trend of decreasing first and then increasing.Among them,the coupling degree and coordination degree of water environment in Yuncheng City are the highest in Fenhe River basin,while the coupling coordination increase level in Xinzhou City is the highest.By 2025,the coupling coordination level of the Fenhe River basin will show an increasing trend and develop towards intermediate coordination.
