Abstract: The conditions of Liaoning metallic mine areas and the heavy metal soil pollution of their surrounding areas, especially the soil pollution of tailing reservoirs and their surrounding areas, are matters worth of attention and research.The soil samples of tailing reservoirs and their surrounding areas in Liaoning typical mining areas were taken, whose Cu, Zn, Pb and Cd elements were analyzed by atomic absorption spectrometry, Hg and As by automatic fluorescence spectrophotometry and Cr by diphenlycarbazide spectrophotometry.Heavy metal pollution assessment was made by fuzzy comprehensive assessment method.The results indicate that heavy metal pollution of soil in Liaoning metallic areas is characterized by a composite pollution composing of  two main heavy metals of Zn and Pb , and three associated heavy metals of Cd, As and Cu.

Key words: Metallic mining area, Disused tailing land, soil polluted by heavy metals, Fuzzy comprehensive assessment
