Abstract	Research on the spatial distribution of soil nutrient content and its variation is important to apply fertilizer reasonably and improve the ratio of fertilizer use. The Traditional Statistics, Geostatistics, and the method of GIS are used to study the spatial variability of soil nutrient and its driving factors in Daxing district of Beijing. The results from traditional statistical show that the variation degree of organic matter, total nitrogen and available K of study area is moderate, and available phosphorus(AP) represents strong variability. Variance analysis showed that the spatial distribution of soil nutrient content is affected by soil texture and land use types, and it is the combined action of nature and human. Geostatistics analysis get the result that organic matter and total nitrogen is medium spatial autocorrelation, while available K and available phosphorus (AP) shows strong spatial autocorrelation. On different scales, we get images of soil nutrient distribution of Daxing District and Panggezhuang town after Kriging Interpolation. The distributions of soil nutrient on different scales show delicate difference.
