Extensive vegetation restoration has been implemented to control severe soil erosion on the Loess Plateau, China. Studying the effects of vegetation restoration on soil physical properties in loess area is of great significance for revealing the relationship between vegetation restoration and changes in soil properties and regional hydrological regimes. It is also important for assessing ecological benefits of vegetation restoration accurately. This study investigated the effects of vegetation restoration on changes to soil physical properties shown by 13 indices (e.g., soil bulk density, porosity, and saturated hydraulic conductivity) in two small watersheds (Zhifanggou and Fangta) in Ansai County, Shaanxi Province. Results showed that vegetation recovery significantly reduced soil bulk density while increased soil porosity, aggregates content (>0.25mm), water holding capacity and permeability. In the short term (40a), the effects of vegetation restoration on soil texture was non-significant. The effects of vegetation restoration on soil physical properties increased with time and decreased with soil depth. Results showed that indices including bulk density, aggregates content (>0.25mm) and saturated hydraulic conductivity were good indicators for evaluation the effects of vegetation restoration on changes to soil physical properties. Due to low soil moisture content, the improvement of soil physical properties by restoration of caragana intermedia and grasslands in this area were better than that of Robinia pseudoacacias. Vegetation restoration in this area should give priority to the construction of secondary shrubbery and grassland.
