中文摘要：

本研究采集了滹沱河干流及其支流共17个采样断面的表层沉积物样品，对其cu、cr、cd、Co、Mn、Fe、I-Ig、Pb、Ni、Se、sn共11种重金属元素含量进行检测，并采用地累积指数法和污染负荷指数法对流域重金属污染水平进行分析评价。结果表明，滹沱河流域表层沉积物中cd含量达到中度污染水平，滹沱河五台县15号采样断面重金属污染达强污染水平，主要污染金属有Cd、CuCr、Pb、Sn，下游深泽段主要污染金属为Cd和Cr。本研究将为滹沱河水系的重金属控制与治理，改善流域水生态环境提供科学依据。

英文摘要：

Surface sediment samples were collected from 17 sample sections in the Hutuo River and its tributaries in this paper, which were analyzed for the concentrations of 11 heavy metals （Cu,Cr, Cd,Co,Mn,Fe,Hg,Pb,Ni,Se,Sn）.The pollution degrees of the heavy metals in the surface sediments were assessed by the index of geo-accumulation （Igeo） and Pollution Load Index （PLI）. Results showed that the surface sediments in the Hutuo River Basin were moderately contaminated by Cd,and the sampling site 15 located in Wutai County were mainly contaminated by Cd,Cu,Cr,Pb,Sn.Besides,Cd and Cr were the main pollution metals in the sample sections located in Shenze County.This research provided scientific basis for the control of the heavy metal pollution and improvement of the ecological environment in Hutuo River Basin.
