摘　　要：为调查磁湖沿岸表层土壤重金属污染情况,对4种有代表性土壤中Cu、Pb、Cd、Zn的有效态含量进行了分析,并采用Lars Hkanson潜在生态风险指数法进行评价。结果表明:沿岸土壤总潜在生态风险程度低,不同来源的土壤土质相差较大,部分土壤受到Pb、Cd、Zn、Cu中等污染,受湖水冲刷的地方,Cu和Zn具有高的潜在生态危害。In order to investigate heavy metal pollution status in Cihu Bank＇s surface soils, the available content of C u,Pb, C d,Zn in the representative soils was analyzed and evaluated by Lars H kanson potential ecological risk index. The results showed that total potential ecological risk of the bank＇s soils was low, there was great difference in the soils from different sources, medium pollution of Pb, Cd, Zn and Cu occurred in some soils, and areas scoured by the lake water had higher potential ecological harm.
