“长江经济带”战略背景下武汉城市水环境承载力综合评价

为揭示长江经济带战略背景下武汉城市水环境承载力的演化特征，理解长江经济带建设过程中武汉城市水环境的承载基础，从水资源环境、水污染控制和社会经济承载3个子系统来构建城市水环境承载力指标体系，采用结构熵权法和均方差决策法进行主客观联合赋权，对长江经济带战略下的武汉城市水环境承载背景进行研究。研究结果表明：（1）2004~2013年武汉城市水资源、环境与社会经济的发展协调性较好，城市水环境承载力综合值呈上升态势，具有较好的水环境承载基础；（2）水资源环境和水污染控制两个子系统在武汉城市水环境承载力中贡献较大；（3）长江经济带建设背景下水污染控制是提升武汉水环境承载力的关键，未来控制城市生活污水、加强城市环保基础设施的建设和管理是武汉城市水环境管理的重中之重

Comprehensive Evaluation of Urban Water Environmental Carrying Capacity in Wuhan Under the Context of the Yangtze River Economic Belt Strategic

To reveal the evolution characteristic of urban water environmental carrying capacity in Wuhan under the background of the Yangtze river economic belt strategy, so as to understand the carrying foundation of urban water environment in Wuhan through the process of the construction of the Yangtze river economic belt, This paper build up the assessment index system of urban water environmental carrying capacity (UWECC) was built up with 3 subsystems, including urban water environment, urban water pollution control and urban social economic carrying capacity. And then a much clearer definition and associated evaluation for UWECC in Wuhan were carried out based on structure entropy weight method and mean squared deviation weight decision method. The results show that: (1) UWECC of Wuhan was increasing in the period of 2004-2013 which means that the development of water resources, environment and eco social were coordinate during the past decades and there is a good foundation for water environment carrying in Wuhan. (2) The subsystems of the water environment and the urban water pollution control contribute more to the UWECC. (3) Water pollution control is the key to enhance the Wuhan water environmental carrying capacity. The water environment management in Wuhan should focus on the control of municipal sewage, and strengthen the construction and management of urban sewage treatment facilities in the future
