摘　　要：本文选取陕西西部彬县煤矿区作为研究地域,利用微波消解仪、火焰原子分光光度计等对Cr、Pb、Cu、Zn、Cd五种重金属元素进行含量测定,运用内梅罗综合指数法、地累积污染指数法和潜在生态危害指数法分别对其进行土壤重金属污染生态风险评价,得出该矿区重金属污染相当严重,且已经有纵向迁移趋势的结论,为后期的环境治理提供一定的理论依据。In this paper, two kinds of heavy metal elements such as Cr, Pb, Cu, Zn and Cd were determined by microwave digestion and flame atomic spectrophotometer. The Nemerin comprehensive index method, The cumulative pollution index method and the potential ecological hazard index method were used to evaluate the ecological risk of heavy metal pollution, and the heavy metal pollution in the mine was very serious and the vertical migration trend had been obtained, which provided some theory for the later environmental management in accordance with.
