摘　　要：东太湖历来是太湖水环境质量最好的湖区,但近3年东太湖出现水环境质量下降、富营养化加重的问题,通过对东太湖水文、水环境、水生态变化规律分析,结果表明下泄流量加大、底泥扰动、水生植被退化是影响东太湖水环境质量的主要原因,通过优化水利工程调度、构建消浪设施以及生态清淤和湖滨带建设等改善东太湖水环境质量的水工程措施,为东太湖综合治理工作提供技术支撑。The East Taihu Lake has always been the Lake area with the best water environment quality. However,in the past three years,the water environment quality of the east Taihu Lake has declined and the eutrophication has increased. Through the analysis of the hydrological,water environment and water ecological changes in the east Taihu Lake,the results showed that the increase of discharge,sediment disturbance and degradation of aquatic vegetation were the main factors affecting the water environment quality. In order to provide technical support for the comprehensive management of the east Taihu Lake,some water engineering measures were put forward,such as optimizing the dispatch of water conservancy projects,constructing wave dissipation facilities,ecological dredging and lakeside zone construction to improve the water environment quality of the east Taihu Lake.
