摘要
引江济太工程是旨在改善太湖水质的重要工程举措,弄清调水过程中输入太湖的污染物负荷量是研究调水效果的重要方面.本研究根据2003年～2008年调水量和望亭立交闸下的水质监测数据,定量地计算了调水的入湖水量和污染物通量.同时根据2000年～2005年环湖30条河道每月一次的水文及水质监测数据,计算每年环湖河道的入湖水量及污染物通量.通过比较结果表明平均每年调水的入湖污染物通量约占总入湖污染物通量的10％,定量地给出了调水对太湖水质的贡献.
A water diversion project,aiming at improving water quality of Taihu Lake by transferring water from the Yangtze River,was initiated in 2002.It was the key point to understand the pollutant fluxes of the water diversion project.Based on the daily in-flowing water quantity of the water diversion project from 2003 to 2008 and the monthly monitoring data of water quality at Wangting Interchange Gateway,this study calculated the seasonal in-flowing water quantity and pollutant fluxes each year.Besides,annual in-flowing water quantity and pollutant fluxes of the surrounding rivers of Taihu Lake were calculated according to the monitoring data of the 30 surrounding rivers of Taihu Lake from 2000 to 2005.Compared the pollutant fluxes of the water diversion project with the pollutant fluxes in surrounding rivers,the results showed that the average annual contribution of pollutants accounts for 10 percents of the total amount of input loads,and the water diversion project had provided the contribution to Taihu Lake quantifieationally.
