AB  - The vegetation growth and distribution characteristics of Hunshandak Sandy Land and Horqin sandy land were investigated in the field, the tree and shrub tree species resources in the sandy land were investigated, the distribution and growth of various tree species were mastered, and the dominant local tree species were selected and determined.This paper studies the conservation function and wind prevention and sand fixation function of shrub sand pile in degraded ecosystem after the phenomenon of shrub desertification in desert grassland area, and takes three typical desert grasslands in Hunshandak Sandy Land, such as almond, Caragana microphylla and Caragana microphylla as the research object. By measuring and analyzing the morphological parameters of three shrubs, the morphological parameters of sand pile and the fractal dimension of soil particles under the shrub, the morphological development of sand pile and the characteristics of soil particle composition, as well as the relationship with the morphological characteristics of plant shrubs and the ability of sand fixation, and the mechanical composition of soil particles at the depth of 0 ~ 60 cm under the three shrubs This paper discusses the relationship between soil fractal characteristics and soil fertility after grassland shrub, and reveals the survival and diffusion mechanism of Shrub Vegetation in desert grassland.The soil under four typical shrubs (Caragana microphylla, Polygonum cuspidatum, Salix mandshurica and Artemisia chabaga) in semi mobile sandy land of Horqin sandy land was selected as the research object, and the vertical distribution characteristics of carbon, nitrogen and phosphorus contents and their eco stoichiometric ratio in each soil layer of different shrub types and the correlation between various indexes were analyzed, In order to clarify the influence and feedback ability of vegetation composed of different shrub types on soil nutrient elements under the same environmental conditions,
