%X Based on measurement of the monthly soil moisture content in 2002 by choosing the different age's S.viciifolia Hance plots in the hilly and gully area of northern Shaanxi province, and(making fallow land and Caraganar land as a contrast,the following conclusions can be drawn from this paper: 1)The annual evapotranspiration of the 5. viciifolia Hance shrub in the sufficiently deep layer of the plots is 590mm and the mean water consumption of individual plant is about 85mm;water consumption is intense from May to July,soil moisture is the least in August and increases in September. 2)The soil moisture in the profile between 0-2.5m is active, the intensity of soil moisture consumption weakens with the increase of soil depth. 3)The depth of the "dry soil profile" is more than 10m that is deeper than the Caraganar's, but it didn't develop further during the two years.
