英文摘要	The distribution of soil particle sizes is closely related to soil health condition. In this study, grasslands under different grazing intensities and different cultivation ages grasslands were selected to evaluate the dynamics of soil particle size redistribution in different soil layers. When the grazing intensity increased, the percentage of 2000 similar to 150-mu m soil particles in the 0-10-cm soil layer decreased; 150 similar to 53-mu m soil particles remained relatively stable among the grazing intensities-approximately 28.52%similar to 35.39%. However, the percentage of less than 53-mu m soil particles increased. In cultivated grasslands, the larger sizes (>53 mu m) of soil particles increased and the smaller sizes (<53 mu m) decreased significantly (p < 0.05) in the 0-10 cm-soil layer with increasing cultivation ages. The increase in small soil particles (<53 mu m) in topsoil associated with grazing intensity increased the potential risk of further degradation by wind erosion. The increase in big soil particles (>53 mu m) in topsoil associated with cultivation ages decreased the soil capacity of holding water and nutrient. Therefore, to maintain the sustainability of grassland uses, grazing grasslands need to avoid heavy grazing, and cultivated grasslands need to change current cultivation practices.
