Temporal and spatial distribution of soil moisture in the loess area of West Shanxi Province is studied by using the geological statistics method.Results show that the variation function model can well describe the spatial features of soil moisture.Soil moisture on different slopes has strong and moderate spatial autocorrelation,which indicates that it has the significant spatial autocorrelation on slope scale.The result can be validated by the fractal dimension.The distribution of soil moisture is analyzed by using geological statistics and a new methodology for temporal and spatial distribution of soil moisture is presented.
