Strategies of the Pollution Control and Ecological Restoration in Taihu Lake Aquatic Ecosystem

Taihu Lake is a mutiple-function fresh water lake situated in the delta of Yangtze River. Nowadays, the serious pollution mainly created by industry and residents' life has made the water quality of the lake decline continuously. Eutrophication is the main characteristic of the water pollution. The water pollution not only affect the several functions of the lake, but also cause the changes of the aquatic biological community. The pollution control strategies to be adopted include the treatment of the industrial waste water and residents' life sewage, as well as the agricultural non-point polluting source. Ecological engineering is the useful measure for diminishing the nutrition salts in water. On the basis of pollution control, the ecological restoration methods include the transplanting of the emerged and/loading anchored aquatic plants at first and the restoration of the submerged plants in the next.;Taihu Lake is a mutiple-function fresh water lake situated in the delta of Yangtze River.
