Abstract

The Fuxian Lake is the largest deep-water freshwater lake in China and is a typical representative of poorly-nourished lake. With the rapid population growth in the lake basin and the accelerating urbanization, eutrophication is threatening the health of the lake. Aiming at the characteristics of poorly-nourished lakes in Fuxian Lake, the paper, based on the carrying capacity of the water environment, focuses on the reduction of the main pollutants emission into the lake, according to the principle from easy to difficult and first things first. Under the guidance of the idea of "one return, two adjustments and three conservations", the paper emphasizes the lake buffer zone and the northern pollution control area of the lake. There have been the treatment key pollution sources along the lake in the Fuxian Lake Basin. The buffer zone retreat and ecological construction, the industrial structure adjustment of the dam area, the green ecological construction of the mountainous and semi-mountainous areas, the control of the water pollution of rivers into the lake and the restoration of the mechanism of fresh water production, and the construction of an integrated river basin management system are established so as to fundamentally reduce the amount of pollutants produced and the amount of water entering, so the water quality’s decline trend has been restrained and the basin ecological environment has been improved significantly. Therefore, the sustainable social and economic development of the basin has achieved and the water environment quality of Fuxian Lake has been maintained steadily.
