Abstract: Studying the effects of different land use patterns on soil physical properties in black soil areas can provide a scientific basis for the protection and sustainable use of black soil.In this paper, four typical land use patterns were selected: bare land, cultivated land, grassland and forest land，physical indexes (GMD and MWD) such as soil bulk density, soil quality and moisture content, water-stable aggregate distribution and aggregate stability were measured in April, June, August and October from soil samples of different soil layers under different land use patterns.The results showed that the soil bulk density and soil mass water content of the four utilization modes changed with depth, and the average soil weight of 0-20 cm cultivated land was 0.06 higher than that of forest land. g/cm³, which was 0.04 g/cm³ higher than that of grassland.The average soil mass water content of forest land was the highest among the four use methods, which was 1.9% higher than that of the lowest bare land.The coefficient of variation (CV value) of soil quality and water content in bare land, cultivated land and grassland had the same change trend, which decreased first and then increased from April to October, and the CV value of forest land changed the least during the year.The distribution of water-stable aggregates in woodland soil showed strong stability, and the fluctuation range of bare land with seasonal variation was the largest.The stability indexes of soil aggregates (GMD and MWD) were as follows: woodland> grassland> cultivated land > bare land. Among the four utilization methods, bare land showed strong seasonal sensitivity, and forest land had the strongest soil water retention capacity and soil stability.
