随着城市的不断发展，素有百湖之城美誉的武汉也面临着城市内湖污染问题。以武汉市内湖——沙湖为例，对其历史状况、治理过程进行了回顾，对其现状进行调查、分析、评价，并提出了外围污水系统完善、外源污染控制、底泥控制、水生植被重建等方面的控制措施。为确保沙湖治理水平在较长时间内良好稳定，在现有工程方案基础上提出了更进一步的水环境管控方案，即自动监测、远程调度、多方协作、水力调度等相结合的长效管理方案。该工程水体治理、生态修复模式可为其他同类湖泊治理提供借鉴。

With the development of urban, there was some problems of urban lake pollution in Wuhan which is famous for the large number of lakes. Taking the inner lake of Wuhan —Shahu Lake as an example ， its historical situation and pollution control process were reviewed， and its current situation was investigated, analyzed and evaluated. Then, the corresponding measures including the improvement of the peripheral wastewater treatment system ， the control of outside source pollution， the control of sediment， vegetation recovery and other aspects were proposed ．To ensure that the level of management could be maintained in a good degree for a long time, a long-term management scheme combining automatic monitoring, remote scheduling, multi-party cooperation and hydraulic dispatching was proposed based on the existing engineering schemes. The water body treatment and ecological restoration mode of the project could provide reference for the treatment of other similar lakes.
