[Objective] The research aimed to study the influences of different land disturbances restoration measures on soil water infiltration characteristics in the hilly area of the Loess Plateau. [Method] Soil water infiltration characteristics under three restoration measures of fish-scale, parallel ditches and ungrazed grasslands were surveyed by double ring method. These restoration measures had carried out five years in typical steppe in hilly area of the Loess Plateau in south of Ningxia. [Result] The measures of fish-scale pits and parallel ditches increased soil water infiltration rate evidently. The results had correlation with the increasing of soil bulk density and porosity caused by land disturbances. The water infiltration process could be imitated by Philip formula. [Conclusion] Land disturbances restoration measures could enhance the soil water infiltration capacity.
