摘　　要：采用单项污染指数法和内梅罗(Nemerow)综合污染指数法,评价治理前后矸石山周围土壤重金属状况。结果表明,矸石内重金属的迁移程度受到日晒、风流等外界等因素的影响,削减后矸石山周围土壤内重金属含量比治理前明显下降。Monomial pollution index method and Nemerow comprehensive pollution index method were adopted to evaluate the content of heavy metal of coal gangue and soil around before and after the treatment.The results showed that the migration degree of heavy metal of gangue was influenced by the sunshine,wind current and so on.Extractable metal content around waste dump after the cut of coal gangue dump decreased obviously.

关 键 词：重金属含量 综合污染指数法 单项污染指数法
