The water quality of Lake Taihu and its protection
- 55 Downloads
Lake Taihu, the third largest fresh water lake of China, with a surface area of 2338 km2, is located in the Changjiang River Delta, the most advanced economic zone in China. It is a typical saucer-like shallow lake in its depth and shape. During the last decade, the rapid economic development of local agriculture and industry both in the urban and rural areas of the Taihu region has made great advances. Great quantities of pollutants have been discharged into the lake, its nutrient content has increased continuously, and phytoplankton blooms have occurred in some areas. Water quality protection in Lake Taihu is very important because of its close relation with economic development and people's daily life. It is urgent to have comprehensive pollution control in Lake Taihu. Based on water quality monitoring data in Lake Taihu from 1986 to 1993, the dynamic variations of water quality and eutrophication trends have been analyzed, showing obvious spatial and temporal variations. The main water quality factors were compared with the standards for drinking water and indicate considerable change with the seasons. Basic strategies to protect water quality and prevent eutrophication are discussed.
