Abstract:: Soil moisture is one of the main factors affecting the growth of plants in sandland. Taking 3 shrubs in Mu Us sandland as study objectives, this paper analyzed the variation of their soil moisture, and tested the difference of soil moisture in top layer between shrubs and bared sandland by Brown-Forsythe method. The results show that the variation of soil moisture is affected largely by root depth and rainfall characteristics. The soil moisture in the depth of 30-50 cm varied obviously because of the water uptake of roots. Soil moisture is the highest in August in 2004, and July in 2005. Artemisia ordosica has significant effect on top soil moisture (Sig=0.04<0.05), and Sabina vulgaris and Hedysarum mongolicum have no siginificant difference with bared sandland (Sig value is 0.239 and 0.308 respectively), which means that Artemisia ordosica can keep the moisture of topsoil.
