Understanding the variation of the soil moisture of different farm-land conversion patters and depth is important for better using the soil water in the Loess Hilly region. Using field positioning continuous observation data, we reviewed the soil moisture between bench grassland and nature grassland in Zhifang catchment of Ansai, Shaanxi Province that soil depth falls into the scope of 0—500 cm. The results of the study show that the effect of rainfall on soil moisture is obvious, and the soil moisture content of bench grassland (13.38%) is higher than that of natural grassland (13.21%); the variation trend of soil moisture content was basically the same in bench grassland and natural grassland; soil moisture content of the layer below 200 cm in the bench grassland is generally higher than that of the natural grassland; soil moisture has obvious difference at different depths in different periods; in the growth period, averaged soil water content moisture content of natural grassland(12.46%) is higher than that of horizontal grassland(11.58%) in 0—100 cm depth, the soil moisture of nature grassland (14.02%) is less than that of the bench grassland (14.44%); the effects of individual rainfall event on soil moisture at different depths are different, and the influence of surface layer is the largest. The results suggest that, some measures of soil and water conservation should be taken to improve the effect of vegetation restoration on the basis of conversion of farmland to grassland.
