The results showed that MGM had good spherical shape and narrow size distribution,and the particles with diameters ranging from 0.13 mm to 0.28 mm were about 91 wt%.The surface hydrophilicity of Fe3O4 microcrystal was improved by formamide dispersing treatment.The gel particles made by the copolymerization of glycidyl methacrylate and N,N′-methylene bisacrylamide could encapsule Fe3O4 microcrystal to produce colloid cores,and uniform and stable MGM microspheres were formed by the conglomeration of the colloid cores.

Then, soil structure was destroyed and formed erodible particles with size 0.154 to 0.18 mm in the soil surface. Under the impact of strong winds and vehicle wheels, soil erosion by wind and vehicle wheels in soil surface was severe, and some fine particles (≤0.063mm) disappeared gradually, so soil structure would evolve to be coarse.

在车轮的碾压作用下草原土壤表面形成易风蚀粒子（0.154~0.18 mm），受强风和车轮的携带作用后表土风蚀严重，很多细颗粒（粒径≤0.063 mm）在车轮的携带和强风的作用下会逐渐消失，土壤表面进一步向粗粒化发展。
