Soil erosion is one of the reasons for soil degradation and the decline of soil cultivated land quality, and the stability of aggregates in soil is an important indicator to measure soil erodibility. Changes in land use patterns may affect soil structural materials such as soil aggregates and related soil physicochemical properties. Therefore, in this study, four land use, namely woodland, shrubland, slope farmland and terraced fields, were selected to analyze the physical and chemical properties of different land use modes and different soil layers through field investigation, field sampling and indoor analysis. The Le Bissonnais method was used to determine the stability of soil aggregates. The results showed that there were significant differences in soil organic matter, total nitrogen, clay, silt and porosity in different land use patterns （p < 0.05）. The contents of soil organic matter and total nitrogen in sloping cultivated land were higher than those in terraced soil. Woodlands had the highest levels of organic matter and the lowest total nitrogen contents, while shrublands had the opposite. The content of clay and silt in sloping cultivated land and terraced soil was higher than that in woodland and shrub soil. There were significant differences in organic matter, bulk density and porosity among different soil depths （p < 0.05）. The porosity of sloping cultivated land and terraced soil is smaller than that of shrub soil. With the increase of soil depth, soil organic matter content and porosity decreased, and bulk density increased. The soil aggregate mean weight diameter and soil structure stability index ( SSI ) were significantly affected by land use（p < 0.05）, SSI values are all greater than 7%, and the risk of degradation of soil structure is low. The MWDfw, MWDws and MWDsw of all samples were 0.28~2.20, 0.83~2.44 and 0.41~2.30mm, respectively. Among the three treatment methods of LB method, the aggregate mean weight diameter of soil aggregates under different land use patterns, in descending order, is pre-wetting shaking, slow wetting, and fast wetting, indicating that the primary destruction mechanism of soil aggregates in the study area is dispersion. The stability of soil aggregates in woodland was the highest, and the stability of soil aggregates in terraces was the worst. After redundancy analysis and stepwise regression analysis, it was determined that soil organic matter, silt, total nitrogen, porosity and clay were several important factors affecting the stability of aggregates. The path analysis results show that there is a significant positive correlation between SOM and aggregate stability, and the path coefficient is the largest. There was a significant negative correlation between TN and aggregate stability. Land use indirectly affected the stability of soil aggregates mainly by affecting SOM, TN, Clay and Silt.
