淀山湖富营养化防治与生态修复技术研究

Research on eutrophication prevention and ecology restoration of Dianshan Lake

淀山湖是上海市最大的天然淡水湖泊,也是黄浦江上游的重要水源保护地,其水质、水量状况对上海市饮用水水源安全具有重要作用。近年,淀山湖水体质量不断下降,尤其是2007年,淀山湖各区域出现了不同程度的蓝藻暴发。基于此背景,在对淀山湖进行前期调查的基础上,提出建设试验工程,通过试验工程的实施形成一套可供修复淀山湖富营养化防治的技术体系,为大规模实施相关工程提供科学依据和技术支持。

Dianshan Lake is the largest freshwater lake in Shanghai as well as the water resources protected field which water quality and quantity is of great importance to the water safety of Shanghai. During past several years, the water quality of Dianshan Lake has been deteriorating. Especially in 2007, blue algae was bloomed seriously. On the basis of preliminary survey of Dianshan Lake, a series of experimental projects were proposed in order to offer scientific reference for the eutrophication prevention in the whole lake.
