摘　　要：对苏州市枫桥工业园区湘江路段的14场有效降雨事件径流污染特性进行了研究。结果表明,该工业区降雨径流水质较差,COD、SS、NH3-N、TN和TP的事件平均浓度(EMC)中值分别达到了119、188、2.30、6.35、0.80mg/L,超过了《地表水环境质量标准》(GB3838—2002)的Ⅴ类水体标准;COD、SS、NH3-N、TN和TP的污染负荷分别为846、1337、16、45、6kg/(hm2.a),是国外工业用地的2～7倍,与我国其他类型用地相比,SS负荷高是其主要特点;该工业区雨水径流的初期效应不明显,且主要污染物指标之间具有较好的相关性,可通过减少SS污染源来削减其他污染负荷。Based on monitoring fourteen effective rainfall events in Xiangjiang Road, Fengqiao Industrial Park in Suzhou, the characteristics of rainfall runoff pollution were studied. The results show that the water quality of runoff is worse. The median event mean concentrations （EMCs） of COD, SS, NH3 - N, TN and TP are 119 mg/L, 188 mg/L, 2.30 mg/L, 6.35 mg/L and 0.80 mg/L respectively, which ex- ceeds the V criteria specified in the Environmental Quality Standards for Surface Water （GB 3838 - 2002）. The pollution loads of COD, SS, NH3 -N, TN and TP are 846, 1 337, 16, 45 and 6 kg/（hm^2 ·a） respectively, which are 2 to 7 times of those in foreign similar research reports. Compared to the other land use in China, higher SS load is the important character for the industrial park. The first flush effect is low. The correlations among different pollutants are significant. So the reduction of SS source can decrease the other pollutant loads.
