Abstract:The paper investigated and compared the soil physical properties of the soils under ten different vegetation types(30 a) in psammophyte garden in Yulin City, which locates in the south of Mu Us sandy land. The results showed that vegetation restoration could improve the soil physical properties. Compared with the moving sandy land, soil bulk density of surface soil decreased by 0.1~0.5 g/cm3 and the soil total porosity increased by 1%~10%. Although the sand grains was still the dominant component of soil particle composition it showed a trend of refinement. The content of 1~0.25 mm decreased significantly, and other size fractions increased to certain degrees. Significant difference was found in different vegetation types on the amelioration of soil. The shrub was better than herb and tree in improving soil properties, of which the Caragana was much superior to other species.
