中文摘要	本文对国内外防沙治沙现状、无机类化学固沙材料、有机类化学固沙材料、有机-无机复合类化学固沙材料的研究进展进行综述.化学固沙是在流沙表面形成一层具有一定结构和强度,能够防止风力吹蚀,又可保持下层水分的固结层.通常包括黏结作用、表层覆盖作用、水化作用、胶凝作用、聚合作用5个方面内容,同时指出存在的问题和发展新型化学固沙材料的必要性和重大意义.这将为沙漠防治理方面开发低成本、高性能、适合植被生长、不污染环境、可降解、可大规模实施的新型化学固沙材料提供技术支撑.
英文摘要	The research progress in desertification combating at home and abroad, involving inorganic chemical sand-fixing materials, organic chemical sand-fixing materials, and organic-inorganic compound sand-fixing materials, are reviewed. The principle of chemical sand fixation is that the fixation forms a consolidated layer with certain structure and strength in the surface of quicksand. It could prevent the wind erosion and keep the underlying moisture. Chemical sand fixation usually includes five aspects, that is, felting effect, surface coverage effect, hydration, gelifaction, and polymerization. The existing problems and the necessity for developing advanced chemical sand-fixing materials are pointed out. The technical support for the development of advanced chemical sand-fixing materials with the features of low cost, high performance, suitable for the growth of vegetation, environmentally friendly, degradation, large-scale executable is provided.
