Water Quality Status of Tangxun Lake and Countermeasures

In order to identify the water eutrophication conditions and characteristics of Tangxun Lake,we took water samples at 11 sites around Tangxun Lake from December,2010 to March,2011.With water total nitrogen,phosphorus,chlorophyll-a,COD and transparency as the parameters,we have analyzed and evaluated chemical factors of water,water quality characteristics,eutrophication level and other aspects of the research,and discussed the influence of different factors on the eutrophication of Tangxun Lake.We put forward basic measures to control the eutrophication of Tangxun Lake.The result shows that Tangxun Lake is at a mild rich nutrition.Industrial wastewater,sewage and aquaculture,etc,are the main pollution sources of Tangxun Lake.Measures are to strengthen the control of industrial pollution,urban sewage and agricultural production,to strengthen the aquaculture with control and scientific management,and to strengthen the ecological restoration project of the lake.
