摘　　要：调查分析了铅锌尾矿的植被组成和重金属含量。发现定居于该尾矿的植物共记录到9种,分布于6个科9个属,形成了六种相对稳定的小群落。重金属含量分析结果显示,Cu含量最高的为鸭趾草,达17.16mg/kg。Zn含量最高为东南景天,达3873.14mg/kg。Cd含量最高的为苦荬菜,达13.64mg/kg。The research analysed the vegetation constitution and the heavy metal content of some Pb/Zn mining gangue,and found out eight types of plants around it,which belong to three sections and nine categories;therefore,it forms seven relatively steady small clusters.The result analysis of the heavy metal content showed that Cu is richest in dayflower with 17.16mg/kg,Zn richest in alfred stonecrop with 3873.14mg/kg,and Cd richest in Ixeris denticulata with 13.64mg/kg.
