Abstract: [Objective and Method]With the aid of Geostatistics, the spatial distribution of soil properties in Artemisia desert grassland of purple soil was described and illustrated and the rational points in sampling of soil in the sloping land were further ascertained. [Result]The results indicated that(1): the spatial correlation of total phosphorus, available phosphorus, potassium, nitrogen, vegetation index (NDVI)was high, so their variabilities were mainly affected by structural factors. Moreover, the spatial correlation of available K and available N was low. (2) In the semi-variance analysis, every object could fit the models perfectly.Organic matter fitted the linear model, total K,total N,total phosphorus,available P,available N,available K and NDVI could be explained by the Gaussian model.(3) The ranges of soil nutrients were 23.58 m-110 m. The spatial variability of all soil nutrients were mainly produced by structural factors and random factors. Based on the semi-variance and Kriging interpolation method, the isolines of soil nutrients were mapped. The spatial distributions of soil organic matter, total-N and available phosphorus were similar to each other,while the available N and available K were clearly different. [Conclusion]The analysis of soil nutrients and vegetation indexes help to analyze the correlation between the spatial heterogeneity of vegetation index and the degree of soil elements (OM, N, P, K) spatial heterogeneity of relevance.
