摘要:
太湖流域实施的调水引流,提高了流域水资源和水环境承载能力,发挥了水利工程在改善水环境方面的综合效益,支撑了流域经济社会的可持续发展.本文在分析近年来望虞河引江水量与入湖水量及入湖水体流经太湖湖湾水体水质变化情势的基础上,分析比较了2007年以来的调水引流期间,望虞河入太湖水体总磷、总氮浓度值与太湖贡湖湾、梅梁湾、湖西及江苏省其它主要入太湖河道的总磷、总氮浓度值,并通过监测结果分析了入太湖水体总磷、可溶性总磷的衰减趋势,从而得出,长江是优质水源,调引长江水为增加太湖水环境容量、改善太湖及区域水环境状况起到了积极作用.

Abstract:
The water diversion implemented in Lake Taihu basin has improved the carrying capacity of water resource and water environment, and expressed the comprehensive benefit of hydraulic engineering to the improvement of water environment. It supported the sustainable development of social economy in Lake Taihu basin. Based on the trend analyses of intake and input water quantity in Wangyu River, and the water quality when the input water running through the Lake Taihu in recent years, this paper compares the total phosphorus and total nitrogen concentrations of input water with that of Gonghu Bay, Meiliang Bay, west lake bay and other main input rivers during the period when Yangtze-Taihu water diversion began since 2007. By analyzing the attenuation trends of the total phosphorus and total dissoluble phosphorus concentrations during water diversion period based on the monitoring results, it is illustrated that the Yangtze River had high quality water, and Yangtze-Taihu water diversion has played a positive role in increasing the capacity of water environment and improving the water environment of Lake Taihu.
Key words:  Total phosphorus  total nitrogen  Yangtze-Taihu water diversion  Wangyu River  Lake Taihu
