摘　　要：以成都市经济区内人工湖塘作为研究对象,分析湖塘沉积物中重金属元素的分布规律。利用地积累指数评价,结果表明沉积物中重金属地积累指数大小顺序为:Hg>Cd>Pb>Cu>Zn>As。湖塘沉积物中Hg是主要污染物质,属强-极强污染,其次是Cd,Pb,Cu属强污染,靠近工业区的东湖沉积物污染最为严重,其次是近郊区的青龙渔场,远郊的朝阳水库污染较轻。The paper chooses the artificial lake-ponds as the research object in the Chengdu economic zone,analyzes the distribution of heavy metal in the sediments,and evaluates with the index of Geoaccumulation.The results indicated the index of heavy metals in the sediment decreases followed Hg〉Cd〉 Pb〉Cu〉Zn〉As.Hg is the main pollutant belonging to the strong-greatly strengthened pollution,Cd,Pb,Cu belongs to the strong pollution.Donghu lake which approaches the industrial district is the most seriously pollution,next one is Qinglong Fishery near the suburb,the pollution of the out suburb Chaoyang reservoir is lighter.
