摘　　要：为了解苏南运河对太湖主要入湖河流污染物通量的贡献,基于一维平原河网水量、水质数学模型,模拟计算了2011年受苏南运河影响的主要入湖河流的入湖污染物通量(COD、氨氮、TN、TP),量化分析了苏南运河对主要入湖河流入湖污染物通量的贡献率。研究结果表明:苏南运河主要影响湖西区的太湖主要入湖河流,对湖西区主要入湖河流入湖通量的总体贡献率约为23%,其中对太滆运河的贡献率最大,约42%,漕桥河次之,约23%,对太滆南运河、社渎港、陈东港污染物通量的贡献率由北向南依次减小。In order to study the pollutant flux influence of Sunan Canal on main inflow rivers of Taihu Lake,a 1-D water quantity and water quality model of the plain river network is established; the pollutant flux,including chemical oxygen demand（ COD）,ammonium（ NH＋4）,total nitrogen（ TN）,total phosphorus（ TP）,in main inflow rivers contributed by Sunan Canal is simulated; and the pollutant flux contribution rate of Sunan Canal on main inflow rivers is quantified. The results indicate that Sunan Canal mainly influence the inflow rivers in the west of Taihu Lake,which is quantified as 23%. Sunan Canal contribute most to Taige Canal（ 42%） and then Caoqiao River（ 21%）. The pollutant flux contribution rate of Sunan Canal on South Taige Canal,Shedu River,Chendong River decrease successively from north to south.
