Abstract
According to the actual area copper tailings,we use Tessier method for the 10 soil samples to do speciation and total analysis,and measure the heavy metal content in Rhus chinensis mill and Comnyza Canadensis(L.) Cronq.,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.
