Abstract: In this paper,the spatial distribution of soil heavy metal contaminations,including Zn,Cu,Cr,Hg,As and Pb,were analyzed using multivariate statistical analysis,geoaccumulation index,the potential ecological risk index and GIS interpolation techniques based on the laboratory analysis on the soil samples collected from Zhundong open pit coal mining.The results showed that:the amount of soil heavy metal contents were in the order as Cr> Zn> As> Cu>Pb> Hg;Soil heavy metal contents of Cr,As and Hg were higher than the regional background value 1.0、4.0 and 3.0 times and higher than the second grade national standard of soil environment quality standard(GB15618-1995)1.0、4.0 and 3.0 times;The variation coefficient of soil Hg contamination was high due to the intensive coal mining activity in this region.A relatively strong correlation (r = 0.65) was found between Zn and Cu,which mainly originated form the parent material.Evaluation results based on the pollution index indicated that soils were severely and moderately polluted by Hg and As.Ecological risk assessment results showed that soils were Hg at high risk,other heavy metals at low risk.Spatially,coal fields,industrial parks,living quarters at the south of the Karamay Mountain were the pollution prone areas.
