Abstract:: Grassland degradation characteristics have been transformed by changes in vegetation primarily for soil degradation stage, to a certain extent, its vegetation change can reflect the status and process of degradation. The wind erosion situation of different degradation stage in Xilamuren desert grassland was studied, which is of great significance for protecting and utilizing grassland resources in this area properly. In this research, the top soils (0-1 cm) of 7 different types of vegetation coverage (0%, 5%, 20%, 40%, 60%, 80% and 100%) were selected. In order to analyze the soil particle size characteristics in desert steppe, laser diffraction technique was used to identify the soil particle size distributions, and the particle size parameters such as the average particle size, standard deviation, skewness, kurtosis and fractal dimension were calculated. The results indicated that:(1) most topsoil particle sizes in desert steppe were mainly sand and silt, while the clay content was low; (2) With the decrease of the coverage, the average particle size became bigger, the sorting characteristics got better and the frequency curve changed by nearly symmetrical to positive skewness and partial negative skewness eventually, the kurtosis changed from the sharp to the flat, fractal dimension increased first and reduced later; (3) the particle size distribution was bimodal distribution, the smaller basic coverage was, the more obvious of the second wave lagged behind, and the lower level of uniform distribution was, the more coarse of particle size of the particles concentration was.
