摘要/Abstract

摘要： 根据对青城子铅锌矿区排土场、尾矿库以及周边地区土壤的取样检测结果，应用地积累指数法和潜在生态危害指数法对土壤重金属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，矿区土壤中Cd，Pb，Hg和Zn的污染最为严重，不同区域的重金属综合污染程度排序为尾矿库＞排土场＞周边农田。根据评价结果，认为矿区周边农田应优先考虑发展林业，待土壤重金属污染状况改善之后再发展农业。

Abstract: For the assessment of the heavy metal soil pollution,samples from the waste dump,tailing mine and its vicinity soils of Qingchengzi Lead-zinc mine area are selectedThe method of index of geoaccumulation and the potential ecological risk index were used to assess the heavy metal soil pollution and to provide a scientific basis for future pollution control and land reclamationThe results showed that the soil was polluted badly by the heavy metal elements of Cd,Pb,Hg and Zn in the areaThe contamination hazard grade of heavy metal in different area lies in the tailing area,the waste dump and its vicinity in turnAccording to the assessment,forestry is the first priority in vicinity of mine area,and then agriculture will be taken after the rehabilitation of heavy metal pollution

Key words: Qingchengzi Lead-zinc mine area, Heavy mental soil pollution assessment, Index of geoaccumulation, Potential ecological risk index
