Abstract: Desertification that causes tens of billion yuan of economical loss annually,which restricts regional continual development severely has been a nationwide problem. Chemical sand fixation is an important method of desertification control due to its low cost, efficiency and suppleness,for which polymer is the main material. The applications of several kinds of sand fixation agents including petrochemical, synthetic polymer, biomass, and superabsorbent polymer for the desertification control were summarized.

Key words: desertification, polymer material, chemical sand fixation
