A field experiment was conducted in the water source area of the South-to-North Water Diversion Project,located in the Dan River basin in Shaanxi Province of China,to study the spatial variability of soil properties for cropland and to determine the loss amounts of soil total nitrogen (STN),soil total phosphorus (STP),soil organic carbon (SOC) and siltclay under natural rainfall.Geostatistical analysis indicated that generally STN,STP,SOC and silt-clay had strong spatial dependence (with nugget ratio < 25%) primarily induced by structural factors.Kriging successfully interpolated the studied soil properties.There were some intrinsic relationships among STN,STP,SOC and silt-clay.The effect of rainfall on the spatial autocorrelation for STN and STP was more significant than that for SOC and silt-clay.
