摘　　要：针对区域环境资源与经济发展不匹配问题,采用耦合协调度模型对西北地区水环境与经济发展系统耦合关系进行分析。结果表明:西北地区经济发展指数整体低于水环境系统综合指数;西北地区水环境与经济发展协调度整体水平较低,除宁夏处于初级耦合状态外,其余4省(自治区)均处于不同程度的失调状态;西北地区水环境与经济发展耦合度处于中低度耦合状态,其系统发展经历了极度失调衰退、严重失调衰退和中度失调衰退3种状态。结果表明:结合区域经济发展特点和水环境空间分布特征,应采取有针对性的措施提升水环境状况和经济发展的耦合水平,推动水环境与经济发展的综合效益最大化。Aiming at the mismatch between regional environmental resources and economic development,the coupling coordination degree model is used to analyze the coupling relationship between water environment and economic development system in northwest China.The results show that the overall economic development index of northwest China is lower than the comprehensive index of water environment system.The overall coordination degree of water environment and economic development is generally low in northwest China.Except Ningxia which is in a primary coupling state,the other four provinces and autonomous regions are all in different degrees of imbalance.The coupling degree of water environment and economic development in northwest China is in a medium low coupling state,and its system development has experienced three states,which are extreme maladjustment recession,serious maladjustment recession and moderate maladjustment recession.It is suggested that targeted measures should be taken to improve the coupling level of water environment and economic development with the consideration of the characteristics of regional economic development and spatial distribution of water environment,so as to maximize the comprehensive benefits of water environment and economic development.
