Abstract:
Taking the burr mallow scrub sand piles of Damao Banner in the desert grassland area as the research object，the method of combining field measurements and indoor experimental analysis were used，the burr mallow scrub sand piles was classified into small，medium and big scrub sand piles，and the relationship between the soil particle size characteristics of the different sizes of the scrub sand piles and the soil physical and chemical properties was studied,in order to provide reference for the prevention and control of desert grasslands and the ecological restoration of degraded grasslands in the region.The results showed that,1) the soil particle sizes of different sizes of Caragana tibetica scrub sand pile were dominated by clay particles (13.72%-19.69%) and powder particles (46.18%-68.64%)；and the fractal dimensions of the distribution of soil particle sizes ranged from 2.68 to 2.77.The fractal dimension of soil particle size distribution was higher in the large and medium scrub sand pile than in the small scrub sand pile.2) The content of SOM，AP and AK in the 0-5 cm soil layer showed the highest in the small scrub sand pile，the highest in alkaline dissolved nitrogen in the 5-10 cm and 10-20 cm middle scrub sand pile，and the highest in organic matter and AK in the 20-30 cm middle scrub sand pile.3) Fractal dimensions of the distribution of soil particles were closely related to the physical and chemical properties of the soil，and the size of scrub sand pile and the depth of soil layer had some effects on the content of SOM，AN，AP and AK.
