In the selected mobile dunes, seven slopes were set up, including down the leeward slope, in the middle of the leeward slope, on the leeward slope, on the top of the hill, on the windward slope, in the middle of the windward slope, and down the windward slope, and one 50cm×20cm sample plot was set up perpendicularly in the direction of the slope. Temperature, humidity and wind erosion intensity were investigated from April to August, and 0-10cm soil samples were collected from the sample plots according to the 5-point method and brought back to the laboratory for the determination of the mechanical composition of the soil, soil bulk weight, total nitrogen and total carbon.
