摘　　要：文章根据安徽铜陵林冲尾矿库复垦土壤的采样检测结果,应用地积累指数法和潜在生态危害指数法对土壤中Cu、As、Zn和Pb 4种重金属元素的污染状况进行分析评价,为土壤改良和植物修复提供科学依据。评价结果表明,复垦土壤中Cu的污染极其严重,As、Zn、Pb的污染较轻。2种方法的对比和分析表明,地积累指数评价法和潜在生态危害指数评价法对于重金属元素的污染评价结果稍有不同,源自2种污染评价方法各有侧重点,对重金属污染的系统评价各具合理性。According to the analytical results of the reclaimed soil in Linchong tailing reservoir of Tongling, Anhui Province, the pollution assessment of the heavy metal elements of Cu, As, Zn and Pb in the reclaimed soil is carried out by using the methods of index of geoaccumulation and potential ecolog- ical risk index. The study is to provide a scientific basis for future pollution control and land reclamation. The result shows that the pollution of Cu is very serious in the reclaimed soil, while the pollution of As, Zn and Pb is in a lower degree. It is clear that the pollution assessment results of the heavy metal elements by the two methods have a bit difference, implying that the two methods have differ- ent priorities in the pollution assessment of the heavy metal elements. However, they are both reasonable in the systematical assessment of the pollution of heavy metal elements.
