为探究调水过程中望虞河水体水质风险状况，对2008年引江济太期间望虞河水质风险进行了识别，并采用三角模糊数的α-截集技术对望虞河各监测断面风险因子进行风险率计算，以分析望虞河各断面水体水质风险率及其风险等级。结果表明，造成望虞河水体水质恶化的风险因素主要为望虞河西岸支流污水汇入及污染物二次迁移；江边闸内断面各风险因子风险率较大，风险等级也较高；虞义大桥断面水体具有较低风险和较高风险两个等级；张桥断面各风险因子的风险率较小，风险等级也较低；大桥角新桥断面水体中除高锰酸盐指数外，其余风险因子风险率都较大，风险等级为较高风险；望亭闸下断面各风险因子风险率为0，无水质恶化风险。

In order to investigate the risk conditions of the water quality of the Wangyu River in the process of water diversion from the Yangtze River to Taihu Lake in 2008 , the water quality risk factors were identified , and triangular fuzzy number α-cut set technology was used to calculate the risk probabilities of the risk factors of several monitoring sections of the Wangyu River .Then, the water quality risk probability and risk level of each section of the Wangyu River were obtained .The results show that the main factors causing water quality deterioration were the sewage inflow from the tributaries of the west bank of the Wangyu River and secondary pollutant migration ;the risk probabilities of the risk factors of the Jiangbianzhanei section were relatively large , and the risk level was relatively high;the risk levels of the risk factors of the Yuyi Bridge section were classified into relatively low risk and relatively high risk;the risk probabilities of the risk factors of the Zhangqiao Bridge section were relatively small , and the risk level was relatively low;the risk probabilities of the risk factors , except the permanganate index , of the Daqiaojiaoxinqiao section were relatively large , and the risk level was relatively high; and the risk probabilities of the risk factors of the Wangtingzhaxia section were zero , indicating that there was no water quality deterioration risk.
