Abstract:: The soil moisture was observed and analyzed in the typical vegetation, such as Pinus tabuleformis, seabuck thorn, manual grassland (Alfalfa), farmland and the natural grassland. The results show: the different vegetation, soil profiles and the growth season had dramatically affect on the soil moisture (P<0.01). In different growth stage of the vegetation, the soil moisture is different. It has stable variety in pro-growth times. But it shows the recede curve in mid-growth season. In different vegetation, the soil moisture show dramatically variable. The moisture of the seabuck thorn is higher than that of the other vegetation. The farmland is lower than seabuck thron. And the Pinus tabuleformis is the lowest. After analysis of soil moisture balance, the growing feasible of the different vegetation in the region is: natural grass land> seabuck thorn > alfalfa > Pinus tabuleformis.
