[Objective] In order to provide a scientific basis for more effectively guiding the sustainable development of soil resources and ecological environmental protection in the loess region of Southern Ningxia Hui Autonomous Region, soil particle size characteristics under different vegetation recovery patterns were studied.[Methods] Field standardized soil samples (0-100 cm) were collected, and 216 samples from nine different vegetation restoration methods (Prunus armeniaca forest, Amygdalus davidiana forest, Hippophae rhamnoides forest, Caragana korshinskii forest, C. korshinskii×P. armeniaca forest, P. armeniaca×H. rhamnoides forest, dam land, alfalfa land, and abandoned land) were measured with a Mastersizer 3000 laser particle size analyzer. The average particle size (M_Z), standard deviation (δ), skewness (SK), and kurtosis (K_G) were calculated by the Fokker and Ward formula.[Results] ① Under different vegetation recovery patterns, the main particle size components were silt (0.002~0.05 mm) and very fine sand (0.05~0.1 mm), and the proportion of silt content in each particle size classification was the largest. The contents of clay, coarse sand, very coarse sand, and medium sand in different vegetation restoration methods tended to be stable, and changed little with increasing soil depth. The content of silt, very fine sand, and fine sand fluctuated greatly with increasing soil depth, and each layer showed different trends. ② The variation of the coefficient of variation of each particle size was basically the same under different vegetation restoration methods. The coefficient of variation of clay was the highest, followed by sand and silt. ③ The average soil particle size followed the order of P. armeniaca×C. korshinskii forest > H. rhamnoides forest > A. davidiana forest > C. korshinskii forest > P. armeniaca forest > alfalfa land > P. armeniaca×H. rhamnoides forest > abandoned land > dam land. The sorting ability of abandoned land, A. davidiana forest, and C. korshinskii forest was better than that of other sites, with H. rhamnoides forest being the worst.[Conclusion] Soil particle size distribution in different vegetation restoration methods was mainly affected by utilization mode, vegetation type, and human activity disturbance.
