Land use has a significant impact on spatial soil moisture patterns, particularly in sensitive and poorly managed regions such as karst grassland of Guizhou. This study identified the factors that control soil moisture patterns under different grazing intensities in the pasture grazing system of Guizhou. Three different levels of goat grazing intensity were sampled for various soil moistures including no grazing, moderate grazing and heavy grazing. The data were analyzed using correlation and geostatistical analysis. The results indicated that obviously trend were showed on the average and spatial heterogeneity of the pasture soil moisture as the changing of grazing intensity and soil profile. Under different grazing intensity, soil moisture content of 0-10 and 10-20 cm layers were for NG > HG > MG, soil moisture content of 20-30 cm were for MG > NG > HG, coefficient of variation were moderate variation (10% < CV < 100%), high soil moisture variation was during medium level of the average water content. Moran"s I autocorrelation analysis show that soil moisture had strong autocorrelation, and the correlation was mainly affected by grazing. Semi-variance analysis showed that spatial distribution characteristics of soil moisture was gathering distribution. The C/(C₀ C) values of soil moisture were varied b during 0.500 to 0.817, which suggested that soil moisture had moderate or strong spatial correlation. The variation region of soil moisture under different grazing intensity were from 2.77 to 15.61 m, which suggested that the ecological process affected by soil moisture was altered under different grazing intensity. The Kriging map further showed a great spatial heterogeneity of the soil moisture content. Moreover, the soil moisture spatial variability in this region mostly contributed to grazing intensity.
