To study the heavy metals pollution status of soils from forest land surrounding coal-fired plant in mountainous area, species community structures of 7 forest lands surrounding Qianbei Coal-fired Plant were investigate. Soil samples were collected at central parts and edge parts of these forest lands, and soils in cropland out of these forest lands were sampled as well. Pollution levels of Pb, Cd, Hg, As, Cu and Cr were analyzed. The results suggested that Pb in soils of forest land was mainly associated with rock weathering; forest trees are good shields against the Pb pollution caused by atmospheric deposition. For Hg and Cd pollution, its protection primary depended on its forest closure and components. According to the single factor and Nemerow comprehensive index method, study region was polluted with Hg, Cd and Pb, and no pollution of As, Cu and Cr in these areas was observed.
