摘　　要：固沙材料是化学固沙措施的核心,伴随材料学科的快速发展,固沙材料变得丰富,具有抗风蚀、保持水分、促进植物生长等多功能一体的固沙材料成为研究热点。本文介绍了固沙剂固沙、保水、促进植物生长等功能,并探讨了固沙剂与环境的互馈效应,以探究固沙剂固沙效果长效性。并针对一些固沙剂含有重金属离子及有毒有害成分,存在严重的环境污染问题,综述了新型的多种环境友好型固沙剂,如亚麻型植物胶、沙蒿胶、聚氨酯固沙剂等,并对此类固沙材料自身的稳定性以及应用发展进行了探讨。Sand fixation materials are the core of chemical sand-fixing measures.Along with the rapid development of the material science,lots of sand fixation materials are now available.Sand fixation materials with multifunctional integration of wind erosion resistance,moisture retention and plant growth promotion have become a hot research target.This paper introduced the features of sand-fixing agents such as sand fixation,water retention and plant growth promotion,and discussed the mutual contribution effect between sand-fixing agents and the environment,aiming to investigate the long-lasting effect of sand-fixing agents.And in view of the heavy metal ions and toxic and harmful components contained in some sand-fixing agents,which had serious environmental pollution,it provided an overview of new kinds of environment-friendly sand-fixing agents,such as linen-type plant gum,sagebrush gum and polyurethane sand-fixing agent.The stability of such environment-friendly sand-fixing materials and their application development were also discussed.
