外文摘要：In this paper, the characteristics of trace metal elements were studied in Elsholtzia harchowensis. The relation of trace elements between plant and soil was studied, and the copper tolerance and mechanism of the plant was discussed in details. The results showed that the trace element contents of the soil was higher, Cu content was highest in these elements, and it was as more 200 times as that of control sites. Cu in the plant was highest in these elements and Cd was lowest. The elements sequence in plant was: Cu> Mn> Zn> Pb> Cd. Element contents in different parts of the plant were: Cu, root> flower> leaf> stem; Cd, leaf> flower> root> stem; Mn, leaf> root > flower> stem; Zn, leaf> flower> stem> root; Pb, root> leaf> stem> flower. There is positive correlation in Cu between plant and soil. The tolerance capacity is higher in the plant.
