主　　题：Vegetation restoration Abandoned ages Soil erosion Vegetation types Abandoned slope Loess Plateau 

摘      要：The impacts of vegetation restoration on the soil erosion have been widely elucidated in the semi-arid ***,the magnitude of soil erosion on abandoned sloping farmland still remained unclear and their responses to vegetation succession were rarely *** main objective of this study is to determine the magnitude of soil erosion along vegetation succession and explore the impact of vegetation succession on soil erosion from abandoned sloping *** observations were employed to monitor the rainfall,runoff,and soil erosion of seven sloping farmland plots with different abandoned ages and bare land from 2015 to *** results indicated that the annual runoff depth and soil erosion modulus of vegetation types were in the range of 0.46 to 5.49 mm·a^(-1)and 1.3 to 24.5 t·km^(-2)·a^(-1),*** vegetation effectively reduced the annual surface runoff and soil erosion with reduction of 73.8% to 97.8%and 98.0% to 99.9% as opposed to bare ***,there were no significant differences in runoff and soil erosion for different vegetation types along *** largest event of vegetation types contributed to 38.7%-44.1% of the annual runoff and 42.5%-66.3% of the annual soil erosion,*** restoration considerably alleviated the contribution of largest erosive event to annual soil *** relationships between soil erosion,runoff and rainfall factors could be fitted well by linear functions,and the performances of regression models in predicting runoff were more satisfactory compared to predicting soil *** Artemisia gmelinii(Agm)+Stipa bungeana(Sb)optimized the trade-off between sediment reduction and runoff maintenance,which should be selected as the suitable vegetation types to achieve the sustainability of socio-ecological systems.
