The exploitation of mine has made a great contribution to the social development. But it has caused a series of environmental pollution problems, especially the heavy metals pollution in the soil. In this paper, we assessed the ideas with a uranium repository surrounding farmland as the research object by using geoaccumulation index and potential ecological risk index. According to geoaccumulation index of each site, it is shows that Mn belongs to no pollution levels, heavy metal Cr, Ni, zinc and Pb belong to light pollution levels; According to the potential ecological risk index, it works out that the area of farmland is mainly polluted by heavy metal Ni and Cu, and heavy metal pollution is more serious in soil near the sewage discharge channels.
