摘要:
通过对2009年环太湖水文巡测及同步水质监测数据整理, 得到2009年环太湖河流入出湖水量以及污染负荷, 并将之与前期文献资料数据进行对比.结果表明, 2009年环太湖河道入出湖水量分别为88.40×108m3、93.27×108m3.入湖水量超过5×108m3的依次为陈东港、大浦港、梁溪河、太滆运河、望虞河.出湖水量最大两条河为太浦河、长兜港, 水量超过20×108m3.宜兴地区入湖污染物负荷较大, 应加强治理;悬浮颗粒物出湖通量大于入湖通量, 且绝大多数从太湖南部地区出湖;总氮滞留率在下降的同时入湖通量在逐年增加;引江济太对太湖总体水质改善有积极作用, 与湖内污染数据对比分析表明出入湖河流水质对太湖影响较大。

Abstract:
By the synchronous environmental monitoring of 49 inflow and outflow rivers of Lake Taihu, this study analyzed the wa-ter quantity and pollutant fluxes of those rivers in 2009, and compared them with the literature data of previous years.Analyses showed that water fluxes of the inflow and outflow rivers were 88.40×108m3 and 93.27×108m3 successively in the year 2009, re-spectively.The 5 largest inflow water fluxes were in the order as Chendonggang >Dapugang >Liangxi River >Taige River >Wan-gyu River and the 2 largest outflow water fluxes were Taipu River and Changdougang.Analyses also showed that the river pollution from Yixing area were heaviest, and should be urgently improved.Also the outflow suspend particle fluxes were extremely larger than that of inflow and most of suspend particle was outflow in the south part of the lake.Furthermore, the total nitrogen and total phos-phorus fluxes increased since 2002.The project of water diversion from Yangtze River to Taihu basin was good for water quality of the lake.Comparison of water quality between the lake and rivers suggested that the inflow river pollutant had important effect on the lake water.
Key words:  Lake Taihu  water quantity  pollutant fluxes  retention rate  water Diversion from Yangtze River to Lake Taihu
