Analysis on Efficiency of Different Measures in Urban Lake Water Environment Treatment for Wuhan

In view of the current problems of high construction intensity, large population density and water quality hard to meet the standard in the catchment area of the lakes in the city, taking Sha Lake in Wuchang District of Wuhan as an example, the effectiveness of the five measures such as "building park", "cut-off point source", "water system connection", "controlling non-point source" and "reducing internal sources" in the treatment of the water environment of the Sha Lake is analyzed. It is proposed that the causes of water pollution the treatment of the water environment of the urban lakes should be analyzed. The measures are tailored due to lake conditions, and precise and powerful.
