Abstract: 【Objective】The objective of this article was to study the changes in soil physical properties with different grazing intensities. 【Method】With grazing field experiment, the effects of different grazing intensities and different types of livestock on physical properties of surface (0-10 cm) soil of grazing grassland and forest land with Caragana korshinskii Kom. were studied at hilly-gully regions on the Loess Plateau -Pianguan, Shanxi Province.【Result】The results showed that grazing intensity directly influenced the physical structure of soil of grazing grassland and Caragana korshinskii Kom. The soil bulk density increased along with the increase of grazing intensity, while water content and soil porosity decreased. Compared with goat selected as grazing livestock, sheep had a lesser that trampling effect on grazing land and the soil bulk density, was relatively small. The water content and soil porosity of the grazing land under sheep is higher than that №under goat. 【Conclusion】 Consequently, the soil properties of the surface layer (0-10 cm) grazing grassland and Caragana korshinskii Kom. are most sensitive to grazing intensity.
