摘要	The spatial variability of soil particle size distribution and fractal dimension (D) values play important roles in both agriculture and environment. They impact soil texture, soil quality, and soil erosion. A grid sampling design was used to collect 325 topsoil (0-20 cm) samples from the Daye watershed (0.54 km(2)) in the water-wind erosion crisscross region of the Loess Plateau of China. Classical and geostatistical methods were combined to determine the spatial variability of soil particle size distribution and D values. The D values in the research area ranged from 1.37 to 2.66. There was a significant sigmoidal correlation between D values and the contents of clay, silt, and sand fractions. The D values of four different land uses could be arranged in the following order: woodland > farmland > grassland > shrubland. Values of D had moderate spatial autocorrelation, and clay, silt, and sand contents had strong spatial autocorrelation in the watershed landscape. The interpolation maps showed that D values could be an efficient way to evaluate the degree of soil desertification and degradation.
