Abstract：Considering the complex relationship between agricultural economy and water resources environment， an evaluation index system of agricultural economy and water resources environment was constructed， which consists of 19 indexes from six dimensions including agricultural input， output， modernization and water resources pressure， state and management. The index weight is determined based on the objective combination weighting method， and the coupling coordination degree and obstacle diagnosis model are used to identify the coupling coordination degree of the two systems and its main influencing factors. Taking Hunan Province as an example， the coupling and coordination relationship is investigated between agricultural economy and water resources environment from 2008 to 2019， along with its spatial and temporal evolution characteristics and influencing factors. The results show that the comprehensive development index of agricultural economy in Hunan Province increases year by year， and the comprehensive development index of water resources and environment system fluctuates violently. The coupling coordination degree of each city and state system (0.362～0.947) exhibited a significant upward trend year by year， and it was in the coordinated development stage (0.797～0.947) by 2019. The coupling coordination degree of the two systems displayed a trend from “central〉northern〉southern” to “southern〉central〉northern”. Agricultural input and output are the main factors affecting the coupling coordination degree of cities and states. The countermeasures to promote the coupling and coordinated development of agricultural economy and water resources and environment system in cities and states of Hunan Province are proposed.
