New urbanization is closely related to the construction of aquatic ecological civilization,and it promotes and restricts each other.Based on the panel data of 30 provinces in China from 2009 to 2018,this paper constructs the evaluation index system of new urbanization and water ecological civilization,determines the weight by using entropy method,and comprehensively analyzes and judges the development status and coupling coordination of new urbanization and water ecological civilization by constructing the coupling coordination model of new urbanization and water ecological civilization.The results show that the coupling coordination degree of new urbanization and water ecological civilization in most provinces and cities is in the state of barely coordination and primary coordination,and is at the level of medium coupling coordination;the overall trend is increasing,and the gap between provinces is gradually narrowing with the advance of time;In terms of regional distribution,the eastern region is higher than the central and western regions.Beijing,Shanghai,Tianjin and other places in the eastern region have realized the high-level coupling of new urbanization and water ecological civilization,while Henan,Anhui,Hunan and other places in the central region still have a large space for improvement. 展开更多
