摘　　要：沿太子河布置34个采样断面,取沉积物样品对其重金属(Cu,Zn,Pb和Cd)含量进行检测和分析,并应用地积累指数法对太子河沉积物重金属污染进行了评价。结果表明:太子河上游断面(本溪市区段和葠窝水库部分断面)沉积物中重金属含量较高;Cd的污染偏重,Cu和Pb其次,Zn无污染;与10年前相比,太子河本溪市区段重金属污染程度有所缓解。An assessment of heavy metal contamination along the Taizi River in Liaoning Province was conducted. The contents of heavy metal （Cu, Zn, Pb and Cd） in sediment samples taken from 34 sampling cross-sections along the Taizi River were detected and analyzed. Geoaccumulation Index was employed to assess the heavy metal in sediments of Taizi River. The results revealed high contents of heavy metal in the sediments of upstream sections （Benxi urban area and partial sections of Shenwo Reservoir）. Results of geoaccumulation indices showed that Cd accounts for the largest part of pollution, followed by Cu and Pb, whereas no Zn pollution was found. Compared with the situation a decade ago, the heavy metal contamination in the reach of Benxi urban area has been relieved on the whole. The results provide basis for the heavy metal treatment in the Taizi River.
