摘　　要：为了解祊河河流沉积物重金属情况,以祊河橡胶坝至沂蒙路大桥段为主研究对象,对河段内8个断面沉积物的3个指标(Cu、Zn、Cd)进行监测调查,参照国内有关标准,建立了适合该区域的沉积物污染评价标准,主要运用潜在生态危害指数法和内梅罗法标准指数法对检测结果进行生态风险和污染程度评价。结果表明:祊河橡胶坝至沂蒙路大桥段沉积物重金属生态危害指数高达3418.5,内梅罗污染指数为6.95,为重度污染,说明祊河沉积物重金属污染非常严重。To know the heavy metal status in the Beng River sediment,taking the river from the Beng river rubber dam to the Yimeng road bridge as study object,three indexes（Cu,Zn,Cd） of 8 section sediments were monitored to build up a suitable standard of sediments pollution assessment for the region according to the relevant standards in China,and the ecological risk and pollution level of monitoring results were assessed by potential ecological risk index method and the Nemero index method.Results indicated that the ecological risk index of heavy metal in the Beng river from the Beng river rubber dam to the Yimeng road bridge was up to 3418.5,Nemero index was 6.95,which showed very serious pollution of heavy metals in river sediments.
