摘　　要：通过地积累指数法和富集因子法,对灵丘县蔬菜产地重金属污染情况进行评价。结果表明,灵丘县土壤中Hg元素显著富集,人类活动影响比较明显;Cd,Pb,Zn元素在不同地点表现出一定的富集现象,说明这些元素也逐渐受到人为活动的影响;其他重金属元素富集不太明显;另外,2种方法都可以对土壤污染进行比较科学的评价,且2种方法得到的结果也比较相似。This paper discussed the heavy metals pollution by the methods of index of geo-accumulation and enrichment factor.The result revealed that content of element Hg was obviously increased due to human activities;Cd,Pb,Zn elements showed some enrichment phenomenon at different locations,which suggests these elements were gradually influenced by human activities; other elements enrichment was not obvious.In addition,two methods could make scientific appraisal for soil pollution,and the results obtained were similar.
