摘要:对水环境容量进行研究，对于协调区域社会经济发展与水资源、水环境关系，实现区域的可持续发展，具有十分重要的意义。随着经济的迅速发展，南京市水环境污染与水环境容量之间矛盾十分突出。通过对南京市秦淮河江宁段水环境容量研究，了解水环境容量现状，实现南京市江宁区水环境容量资源的优化配置。本文通过水文特征、水环境现状，同时结合水环境容量计算方法，对其水环境容量进行计算分析，从而为该地区水污染控制规划提供了依据。

Abstract：It is very significant that conducting studies on water environmental capacity in order to coordinateregional socio-economic development with water resources and water environment relations and realize the regional sustainable development. With the rapid economic development , the contradiction between the Nanjing water environment pollution and water environmental capacity is very conspicuous. By researching the water environmental capacity and understanding the present situation of the water environmental capacity in Jiangning section of the Qinhuai River in Nanjing.We can achieve the optimal allocation of the water environment capacity resources of Jiangning district in this paper, we calculate and analyze its water environmental capacity by combining the hydrological characteristics , water state of the environment with the method of calculating the water environmental capacity, and then a basis for controlling the regional water pollution programs is provided.
Key words：Jiangning Section of the Qinhuai River； Water environmental capacity； the model of water environmental capacity
