Abstract

This study was performed to study the effects of vegetation restoration models on soil detachment by overland flow and soil resistance to rill erosion as reflected by rill erodibility and critical shear stress. The undisturbed soil samples were collected from five 37-year-restored lands of abandoned farmland, korshinsk peashrub land, black locust land, Chinese pine land and mixed forest land of amorpha and Chinese pine. It is shown that vegetation recovery decrease rill erodibility but increase critical shear stress. Soil cohesion and plant roots have great effect on soil detachment process. Besides, the low rill erodibility in the restored lands always had a low soil detachment capacity, while the critical shear stress in the restored lands varied non-monotonically with detachment capacity. The mixed forest land of amorpha and Chinese pine was considered as the best restoration model for its important role in reducing soil detachment capacity
