Analysis and assessment of the impact of South-to-North Water Diversion Project on water environment of Nansihu Lake

The Nansihu Lake is an important water source in Shandong Province and is one of the main impounded lakes in the South-to-North Water Diversion East Route Project. With the development of social economy, many environmental problems have appeared in this area, such as lake swamping, shortage of water resources, water pollution, deterioration of ecosystem, etc. In this paper, the current situation of water environment quality is analyzed, and the water environment quality after the implementation of the South-to-North Water Diversion Project is predicted and evaluated. The results show that the water environment quality will be improved greatly after the water diversion, and that the degraded ecosystem will be restored.
