In order to evaluate the influence of vegetation restoration on soil properties of the abandoned land
in the paper we adopt the spatio-temporal substitution method
and took the abandoned land at different stages in Loess Hilly Region as the research object. By combing with laboratory experiments and physiochemical analysis
soil infiltration and anti–scouribility were studied through the point-source infiltration method and undisturbed soil erosion experiment. The results indicate that: at the same abandoned stage
initial infiltration rates(IIRs)
stable infiltration rates(SIRs)
average infiltration rates(AIRs)
and anti–scouribility (AS) decrease with the increasing soil depth. As the abandoned stage extended
the initial infiltration rates(IIRs)
stable infiltration rates(SIRs)
average infiltration rates(AIRs) and anti–scouribility (AS) in surface layer increased significantly after the first pre abandonment
then gradually stabilized. The differences in abandonment phase was significantly greater than that between the soil layer. In the Loess Hilly Region
the Kostiakov model could effectively characterize the initial infiltration rate
and the correlation coefficient was 0.999 1. The Fang Zhengsan model parameters |1 and K could simultaneously characterize the initial infiltration rate and stable infiltration rate
the correlation coefficients was 0.869 4 and 0.998 1
respectively. Its initial infiltration rate was not as good as that of the correlation of the Kostiakov model. The process of soil infiltration could be well described by combining Kostiakov model and Fang Zhengsan model.
