摘　　要：本文选取了东平湖入湖口、湖中心和出湖口3个区域进行采样,分析了底泥中Cr、Pb、Cu、Cd这4种重金属的含量,并采用潜在生态风险指数法对东平湖底泥中重金属生态风险进行了评价。结果表明:东平湖底泥Cr、Pb、Cu、Cd元素平均含量均超过了山东省土壤背景值;东平湖底泥重金属含量在不同区域的分布特征为入湖口≥出湖口>湖中心;综合生态风险水平均处于低水平。This paper selected three areas:the inlet,the center,and the outlet of Dongping Lake for sampling,analyzed the contents of four heavy metals(Cr,Pb,Cu,Cd)in the sediments,and evaluated the ecological risk of heavy metals in the sediments of Dongping Lake using the potential ecological risk index method.The results show that the average contents of Cr,Pb,Cu,and Cd elements in the sediments of Dongping Lake all exceed the soil background values of Shandong Province;the distribution characteristics of heavy metal contents in the sediments of Dongping Lake in different areas are inlet≥outlet>center;the comprehensive ecological risk level is low.
