Geographic information system(GIS) combined with geostatistics was applied to reveal the spatial variability of heavy metals and its affecting factors including Cu,Zn,Pb,Ni and Cd in Shuangcheng of Heilongjiang province.The results showed that Zn,Ni and Cd had a strong spatial correlation,which were affected by intrinsic characteristics of soils,whereas the spatial correlation of Cu and Pb were moderate,indicating that they were affected by intrinsic properties of soil and random factors together.The ranges of Cd,Pb were smaller than that of Cu,Zn and Ni,indicating that the 3 former heavy metals were affected by smaller range factors.The spatial variability characters of heavy metals in studied area soils were as follows.The contents of Cu and Ni decreased from east to west,and contents of Pb decreased from south to north,whereas the distribution of Zn was block-like and Cd was insular.Intrinsic and random factors were the main factors of driving forces of the heavy metals'distributions.Intrinsic factors included soil types,the characteristics of soils,elevation and so on.Random factors included towns,roads,factories and so on.
