Abstract:: Soil water dynamics of individual rainfall during the process of vegetation restoration in typical steppe was studied in the mountain area of southern Ningxia, and elucidated the effects and mechanism of vegetation restoration. The results show the soil moisture content and soil moisture storage was enhanced by individual rainfall in different period of closing, manifested as 1 d>3 d>7 d. Enclosed steppe improve resource utilization rate of individual rainfall, soil moisture in 0-60 cm and soil moisture storage in 0-100 cm increased with period of closing. There was no effects of supplementary irrigation under depth 100 cm. The enclosed time longer, the deeper water active layer was. The water active layer, which reached 0-60 cm after 17-year of closing, was 0-40 cm in slope farmland. Soil structure was the key influencing factor of the soil moisture storage in 0-100 cm on the first day after individual rainfall. From the first day to the seventh day after individual rainfall, the biomass was higher, the more the soil water was consumed in 0-200 cm.
