A field survey on the content of heavy metals in soils and plants in lead-zinc mining area of Duyun Niujiaotang was carried out, and the absorption and accumulation characteristics of heavy metals between plants and soil were compared. Results showed that the soils and plants in the mining area were highly contaminated by Cd and Pb. Among 9 species of the collected herbaceous plants, the contents of Pb, Cd in the stem and leaf of Ficus tikaua Bur are the highest, with BCF 1.32 and 0.96 separately, and translation coefficient 2.64 and 2.96 separately. Buddleja Lindleyana Fortune and Chrysanthemum indicum L had low tolerance of Pb, Cu and Cd, with BCF less than 0.5 mostly, but the translation coefficient approximate or higher than 1. The above 4 plants have a better potential and practical use in phytoremediation as their favorable resistibility to Pb and Cd, and heavy metals content in the above plants don't reach the standard of the hyperaccumulator.
