Abstract: Though first-hand investigation and laboratory analysis , the text studied the heavy metals content status of soil in Hongtou Mountains copper ore areas, and adopted single-factor pollution index method and Nemerow integrated factor pollution index method to evaluate the heavy metals contaminated degree of soil in Hongtou Mountains copper ore areas. The findings indicated that average content of copper, zinc, lead, cadmium in the studied areas exceeds the background value of the local soil, and the soil is seriously contaminated by copper and cadmium, at the same time the contaminated degree of zinc is light pollution, but the content of lead is in safe grade. The content of the heavy metals of soil in different areas exists large differences. The descending order of the composite contaminated degree of heavy metals of soil in every areas is gangue areas> mill run areas>mining areas>surrounding farmland areas.
