The key of phytoremediation was researches and selecting of dominant species in the lead-zinc tailings. This assay analyzed the amount of heavy metals, and the enrichment and transporting features of heavy metals, such as Pb, Zn, Cu, Cd and Mn, in the dominant species in the district, and then we can select the pioneer plants for ecosystem restoration of the area. Results showed that there were 40 species of higher plants, which belonged to 40 chasses and 22 families in the area. And we selected 15 dominant species by heavy metals. Among these dominant species, the content of Pb in Ficus tikoua was 4. 01 times higher than that in other plants, the transfer factor (TF) was 3.91, and bioaccumulation factor (BCF) was 14.4. The capability of TF and BCF of Ficus zikoua was high, so Ficus tikoua had potentials in phytoremediation of heavy metals in polluted area and its enrichment capability of Pb was worth for the further research. Apart from Ficus zikoua, other 14 kinds of dominant plants had a better tolerance in metal pollution in tailings, and they can be used as pioneer plants of ecological rehabilitation in lead-zinc tailings in Xiashuiwan.
