Soil nutrients is one of the important signs and indicates of soil fertility,land evaluation and land management.In based on spatial statistical analysis and GIS in the farming-pastoral zone,the spatial features of soil nutrients were analyzed.Spatial autocorrelation showed that the Moran's I of soil organic matter is sensitive to the scale,but total nitrogen(TN),P and K is not sensitive to the scale.The space of organic matter,TN and P is positive at 0~60 km and negative out of 60 km.The effective range of K(33 000 m)was larger than TN(11 000 m),and P(3 000 m).The effective range of soil nutrients is negative to the fractal dimension.soil organic matter and K were fitted by exponential model,or spherical model was better for TN and P.
