摘要
根据铜矿尾矿库区实际情况,采用Tessier形态分析方法,对所采集的10个土壤样品进行了赋存形态和总量分析,并对优势植物盐肤木、狼尾蒿中的重金属含量进行了测定。分析结果表明:土壤中重金属向植物体内的转移过程与重金属的种类、化学有效态以及土壤和植物的种类特性有关,并且重金属在土壤中的含量和植物的不同部位之间存在一定的线性关系;同时,通过植物实验分析为该地区土壤中重金属的污染治理提供了依据。
According to the actual area copper railings,we use Tessier method for the 10 soil samples to do speeiation and total analysis, and measure the heavy metal content in Rhus chinensis mill and Comnyza Canadensis （L.） Cronq. 0 which are the dominant plants. The results show that the transfer process of heavy metals in soil to plants is interrelated to the heavy metal type,Chemical effective state and characteristics of soil and plant species,and there is a certain degree, of linear relationship between the soil＇s heavy metal content and content in the various parts of plants,then we provide a basis of the heavy metal pollution control for the region through the plant experimental analysis.
