| Abstract: | Element accumulation and distribution of Vetiveria zizanioides and some dominant plants in V. zizanioides community were studied in Tiantai lead-zinc mine area, Zhejiang,China.,and relations of plants with soils and the heavy meatal tolerance of V. zizanioides were analyzed. The results showed that metal element contents of V. zizanioides in sequence were Zn>Pb>Cu>Cd.Contents of Cu in the plant in sequence were root>stem>leaf,Cd leaf>stem>root,and Zn and Pb root>leaf>stem, contents of Zn and Pb in V. zizanioides were significantly higher than those in other plants. There was significant correlation in Zn contents between plants and soils, and the next was in Pb contents. V. zizanioides plant had higher lead-zinc tolerance than other plants.
