Abstract:Using the 10 year observed data of runoff and sediment in the loess hilly forest region and the field antiscourability tests,the anti-scourability in the forest-land and the reclaimed lands were analyzed. The results showed that the forest-land had the strong anti-scourability. After reclaimed,the anti-scourability of reclaimed lands had the decrease tendency from 4.01g/L to 25.51g/L in the flow of 3 L/min,which would increase the soil erosion intensity. Correlation analyses found that the soil shear strength had the biggest effect on soil anti-scourability,and then,the water stable aggregate and the organic content. So it could control effectively soil erosion to return reclaimed lands into forest or grass land,and recover or reconstruct vegetation.
