Abstract: Asurvey of soils and ten plants growing on the soil polluted by Manganese mine tailings in Xiangtan city was conducted.Analysis result indicated that the exceptional-high concentrations of Mn was found to be the limiting factor for plant growth. The concentrations of Mn, Pb, and Cd in the ten plants and Mn-enrichmentalabilities of the ten plants were analyzed in this paper.Poa pratensts, Gnaphalinm affine, Pteris viltata L., and Phytolacca esculenta Van Houtte were proved to have good metal-enrichmental and Mn-tolerant ability. Poa pratensts, Gnaphalinm affine and Pteris viltata L.were Pb-tolerant plants. Comnyza Canadensis (L.) Cronqs, Poa pratensts, and Gnaphalinm affine were Cd-tolerant plants. However, no hyperaccummulators of these three heavy metals were found in the survey. Further research on improved culture experements were still in process.
