Geostatistics has proven to be useful for characterizing and mapping spatial variability of soil properties. Provided with the development of GIS and GPS, in this paper, the spatial characteristic of Ni contents in soils of Beijing was studied using geostatistics. Some 349 samples of surface soils were collected from suburbs of Beijing. Spatial structure was described with variogram. The results show that well-defined structure with nonzero nugget effect, distinct sills and ranges and can be fitted with exponential model (R2 = 0.75, p < 0.01), which is mostly influenced by parent materials. The relative range will reach 8 km. The spatial distribution of Ni contents shows that Ni contents of soils are high in southeast district and low in northwest district, which is influenced strongly by anthropogenic factors (metal smelting and petroleum industry) functioned by natural conditions of wind and river. Variogram analysis shows that the spatial structure of Ni has geometric anisotropy whose ratio is 1.3. The major axis is in NE-SW direction in which there is the longest range. In this study, using background value as standard, Ni pollution was not found in soils of Beijing.
