Abstract:: The properties and heavy metal contents of soil samples taken from 6 function areas in Dabaoshan Mine were measured and the relationships between them were tested. The results showed that the contents of soil Cu, Zn, Pb, and Cr in Open-pit Mining Area were the highest; the contents of soil Mn and Cd in Caoduikeng Tailings Reservoir were the highest. The soil heavy metal contents of most area in Dabaoshan Mine were higher than grade Ⅲ of national environmental quality standard for soils. The variability of heavy metal contents of different areas was significant, which was related to the functions and origin of the soils. There was strong correlation between soil Cu, Pb and Zn content, and they were also correlated to sand particles positively, showing that the high contents of soil Cu, Pb and Zn maybe were caused by human disturbance. There were positive correlations between contents of soil organic matter and Cu, between pH, available potassium, silt particles and Mn and between CEC, available potassium and Cr. There were negative correlations between contents of total nitrogen, pH and Cu, between available nitrogen and Mn, between organic and Cd and between total phosphorus, total nitrogen, pH and Cr.
