英文摘要	PurposeExtensive vegetation recovery has been implemented to control severe soil erosion on the Loess Plateau, China. However, no systematic study has been done on the soil improvement benefit and preferable pattern of vegetation rehabilitation. In this study, the effects of vegetation restoration on soil physical properties at ten sites with different vegetation types and varying restoration periods were investigated.Materials and methodsThe experiment was carried out in the Yanhe river basin in the hilly-gully region of the Loess Plateau. Ten sites, including two replanted arboreal forests for 25 and 35years, three replanted scrubland for 15, 30, and 45years, four secondary natural grassland for 10, 20, 30, and 40years, and one farmland, were selected for soil sampling. Sampling was conducted at 0-20cm and 20-40cm layers.Results and discussionVegetation restoration significantly decreased bulk density, and increased aggregate stability and saturated hydraulic conductivity (Ks), while their effects on porosity was complicated. The soil texture class did not change with vegetation succession, but minor differences in sand, silt, and clay components were observed. Bulk density, macroporosity, and >0.25mm aggregate stability were the principal physical parameters that affected Ks. Moreover, bulk density had the most effect on Ks (-0.84), while >0.25mm aggregate stability had the lowest impact (0.38). Bulk density and Ks were correlated with most of the other soil physical properties. Replanted scrubland and secondary natural grassland had higher soil physical quality index (S-Dexter) than replanted arboreal forests and farmland.ConclusionsIt is reasonable to take bulk density and Ks as the indicators to evaluate the effect of vegetation restoration on soil physical properties. Planting shrubs and grassland is better than forest for eco-environment rehabilitation in the study area. Results of this study provide a reference to regional eco-environmental rehabilitation and conservation.
