Abstract: In order to realize the effective restoration of the degenerative environment in hilly region and select the suitable vegetation restoration models, the dynamic changes of soil moisture of 6 vegetations under the representative months were analyzed with the fixed monitoring on the field. The results showed that the soil moisture of vegetations varied greatly in the different months and it had the definite characteristics. For all the vegetations, the variation of soil moisture in soil superficial layer was greater than that in soil deep layer, and with the soil depth increased, the tendency of the variation for soil moisture was: firstly decreased, then increased and finally decreased. The distributions of soil moisture for all vegetations present fall-S shape in the investigated months, and the variation extent of soil moisture in November was greater than that in April and July. According to the comprehensive analysis for all the vegetations, locust+alfalfa land and wild grass land was better compared to other vegetations. In addition, the specific characteristics of soil moisture variation for every vegetations were also found.moisture in soil superficial layer was greater than that in soil deep layer, and with the soil depth increased, the variation of soil moisture first decreased, then increased and finally decreased.

In addition, the specific characteristic of soil moisture variation under the different months was also found for every vegetation.
