Abstract: Soil polysaccharide is the main form of the carbohydrates in the soil, it is one of the most important organic cementing materials. From the source, composition, content and distribution of soil polysaccharide, the chemical structure of soil polysaccharide, the stability of soil polysaccharide, the role of soil polysaccharide on soil structure formation and the meaning of soil fertility and so on were studied. Soil polysaccharide of extrac?tion and determination methods, physical and chemical properties, soil aggregate and micro aggregate forma?tion and the modified mechanism of the role of soil structure remains to be further in-depth study.
