A geostatistics method combined with GIS was applied to the study of the spatial distribution of total soil Zn and available Zn in the typical area of southern Jiangsu province. The results showed that the total Zn and available Zn had a relatively good correlationsip and their ranges of correlationship extended to about 6.6km and 7.5km, respectively. The distribution maps of the total Zn and available Zn drawn based on kriging interpolation depicted their spatial distribution features. Total Zn and available Zn contents were positively correlated with soil clay (<0.002mm) content, but negatively correlated with soil sand (0.02-2mm) content.
