为了探明As、Sb和Bi在土壤的分布及其在植物体内的累积特征，以贵州省某地锑矿区土壤及植物为调查对象，研究了土壤剖面及植物不同部位 As、Sb和 Bi的分布特征。结果表明：采样点土壤 As和Sb的最高含量分别为118．13 mg/kg和410．91 mg/kg，分别为贵州省土壤背景值的5．91倍和183．44倍；土壤剖面的As、Sb和Bi含量随土壤深度增加呈降低趋势，尤以Sb最为明显；土壤As和Sb的含量与土壤有机质呈正相关，与土壤含水率呈负相关。芒萁、白茅和头花蓼虽不是 Sb 的超富集植物，但作为乡土植物，能适应As、Sb和Bi污染的土壤，可作为该矿区生态恢复的先锋物种。

In order to explore the distribution characteristics of As,Sb and Bi in soil profiles and accumulation features in the plant,in a large antimony mine area,a study was conducted to analyze the pollution status of soil profiles and accumulation of different organs of plants for As,Sb and Bi.Results:The highest As and Sb content was respectively 118.13 mg/kg and 410.91 mg/kg,5.91 and 183.44 times of Guizhou soil background values separately;The contents of As,Sb and Bi in soil profile decreased with soil depth increasing,especially Sb.The contents of As and Sb was positively associated with soil organic matter and water content of soil along with negative correlation.Dicranopteris dichotoma,Imperata cylindrica and Polygonum capitatum were not Sb ,but could concentrate As,Sb and Bi,which could be used as pioneer plants for revegetation of contaminated soil in mine area.
