Improving soil anti-erodibility is the effective approach to prevent soil erosion and restore vegetation.One year abandoned land was taken as control,the soil-erodibility of five vegetation restoration models such as Robinia pseudoacacia L. (RP21),Caragana korshinkii Kom.(AK18),Pinus tabulaeformis Carr.(PC16),R.pseudoacacia-A.fruticosa(RA20),P. tabulaeformis-Amorpha fruticosa L.(PA17)were studied.The results showed that the soil anti-erodibility was improved obviously compared to fallow land.The contents of soil organic matter,clay particles and aggregate degrees between soil particles were increased obviously.Soil organic matter content,water-stable aggregates content,mean weight diameter of water stable aggregate,aggregate degree and dispersion coefficient were used to evaluate the anti-erodibility quantitatively. The order of anti-erodibility with different vegetation restoration models was:Pinus tabulaeformis Carr.,Robinia pseudoacacia L.,Caragana korshinkii Kom.,P.tabulaeformis-A.furticosa and R.pseudoacacia-A.furticosa.In a word,the soil anti-erodibility of pure forest is higher than that of mix-forest in loess hilly area.
