摘　　要：长期以来,在高盐沙地治理的过程中,一直存在着固沙材料耐盐性能差、易粉化的问题。迄今为止,还没有可对高盐沙地进行治理的有效材料。面对我国高盐沙地面积仍在扩大的严峻形势,开发出能有效遏制高盐沙地的适用材料及方法,是一项十分紧迫的艰巨任务。因此,从现有高分子固沙材料在高盐沙地固沙的研究中存在的不足出发,探讨了高分子材料用于高盐沙地固沙效果差的主要影响因素,并深入分析了高分子乳液在高盐沙地固沙过程中的可行性,最后提出具有特定结构及生态效应的高分子乳液将是高盐沙地用固沙材料未来发展的方向。For a long time, in the process of controlling salty desert, the sand-fixing materials used in salt-affected sandy land are ongoing problems, such as poor salt resistance and easy pulverization. So far, there have been no effective sand-fixing materials for salty desert restoration. In order to solve the problem that salt-affected soils suffering desertization is still expanding, the development of the new sand^fixing materials for salty desert restoration is a very pressing task. Therefore, based on the deficiencies of sand-fixation materials used in salt-affected sandy land, for the first time, they analyze and study the influence factors of sand-fixing materials used in salty desert from the principle of materials science. And then, they further analyze and study the theoretical feasibility of polymeric emulsions used sand-fixation in salty desert. Finally, it is pointed that polymeric emulsions with a specific structure and the ecological effect will be the development direction of ecological sand- fixing materials used in salt-affected sandy land.
