望虞河引江对太湖的影响研究

从望虞河引长江水入太湖以加大流域水资源承载能力 ,缓解流域水污染形势 ,是近期治理太湖的应急措施 ,但引水存在各种影响。以 2 0 0 0年和 2 0 0 1年有关望虞河引江资料为分析基础 ,从水量、水质、水环境容量、富营养化、水交换周期与泥沙等方面分析长江水对太湖的影响 ,并初步探讨了引水时机与太湖调度方式 ,为提高“引江济太”的效能提供对策措施

Impacts of Water Diversion from Yangtze River on Water Environment of Taihu Lake

The water diversion from the Yangtze River to the Taihu Lake via the Wangyuhe River is an emergent measure to increase the bearing capacity of water resources and mitigate water pollution in the basin, but the measures may cause some adverse impacts. Based on the analysis of data of water diversion via the Wangyuhe River from 2000 to 2001, the impacts of water diversion on water environment of the Taihu Lake are analyzed from the aspects of water quantity, water quality, water environment capacity, eutrophication, water exchange period, and sediment. Furthermore, the time and mode for water diversion are discussed, providing countermeasures for the improvement of the efficiency of water diversion.
