摘　　要：辽宁省金属矿区及其周边土壤重金属污染状况,尤其是尾矿库及其周边土壤污染是值得关注和研究的问题。采集了辽宁典型矿区尾矿及其周边的土壤样品,用原子吸收分光光度法分析Cu、Zn、Pb、Cd元素,用原子荧光分光光度法分析Hg、As元素,用二苯碳酰二肼分光光度法分析Cr元素,并采用模糊综合评价方法进行了重金属污染评估。结果表明:辽宁省金属矿区土壤重金属污染以Zn、Pb两种重金属为主,同时伴生着Cd、As、Cu3种重金属的复合污染。The conditions of Liaoning metallic mine areas and the heavy metal soil pollution of their surrounding areas, especially the soil pollution of tailing reservoirs and their surrounding areas, are matters worth of attention and research. The soil samples of tailing reservoirs and their surrounding areas in Liaoning typical mining areas were taken, whose Cu, Zn, Pb and Cd elements were analyzed by atomic absorption spectrometry, Hg and As by automatic fluorescence spectrophotometry and Cr by diphenlycarbazide spectrophotometry. Heavy metal pollution assessment was made by fuzzy comprehensive assessment method. The results indicate that heavy metal pollution of soil in Liaoning metallic areas is characterized by a composite pollution composing of two main heavy metals of Zn and Pb , and three associated heavy metals of Cd, As and Cu.
