[Objective] The soil aggregate stability and soil erodibility in different vegetation types of exposed feldspathic sandstone regions in the Baojiagou watershed were studied in order to provide scientific guidance for vegetation construction and reducing coarse sand into the Yellow River. [Methods] Soil aggregate stability and soil erodibility in different vegetation types were evaluated by using the Le Bissonnais method. [Results] ① Under the conditions of the slow-wetting treatment, soil structure was dominated by 2 mm and larger aggregates. Under the conditions of the pre-wetting disturbance treatment, the proportion of 2 mm and larger aggregates was 14.79%~40.17%. Under the conditions of the fast-wetting treatment, the content of 2 mm and larger aggregates was 4.69%~15.11%. ② The destruction rate of soil aggregates was influenced by vegetation, and followed the order of bare land > grass land > Pinus tabuliformis forest > Prunus armeniaca forest > Caragana korshinskii forest > Hippophae rhamnoides forest. ③ The soil erodibility K value in the exposed soft rock area ranged from 0.045 to 0.092, and the disintegration rate of soil in different vegetation types ranged from 0.48 to 1.38 g/min. [Conclusion] H. rhamnoides and other artificial vegetation can significantly enhance the stability of soil aggregate structure, reduce soil erodibility, improve soil corrosion resistance, and thus effectively reduce erosion and sediment yield processes.
