中文摘要	采用液相化学方法，微乳化、高剪切和非均相混聚技术，以风化煤和废弃塑料为主要原料，研制了集提供养分、固沙保水、改良土壤、修复荒漠化土壤作用于一体的3种多功能固沙保水剂，通过试验研究，优化出一组固沙保水剂。结果表明，该固沙保水剂的胶团粒径为20～60nm，固结层抗压强度为5．30-16．10MPa，抗冻融性能和耐老化性能良好，在风速15m·min^-1和25m·min^-1连续吹30min、在风速30m·min^-1吹5min均未见起尘及风蚀现象，抗风蚀性能显著。
英文摘要	Desertification of lands is one of the most serious ecological problems in China. Three mature methods, namely engineering sandfixing, biological sand-fixing and chemical sand-fixing, can be applied to control and recover the desert. Former two not only take time and effort but also capital intensive. Therefore, chemical approaches aim at sand-fixing, water-maintaining and nutrimentsoffering have been an alternate option. In this paper, three types of muhifunctional sand-fixing and water-maintaining polymer（humus-plastic polymer, plasticstarch polymer and air-slake coal polymer）, which could provide nutriments, fix sand, preserve water, remediate soil and recover desert, were made from the air-slake coal and the abandoned plastics by liquid chemical method, emulsification, high velocity cutting method and mixing in non-homogeneous solution. The characteristics of the polymers such as particle size distribution, viscosity, anti-press intension, freezethaw capacity, aging capacity and anti-windy capacity was analyzed to select one polymer with excellent sand-fixing and water-maintaining characters. The results indicated that all three types of polymer not only decreased water evaporation under no vegetation, for example, in 15 days the control evaporated 99.8%, while three types polymer evaporated 98.2%, 98.1% and 97.4% in 50 days respectively, but also increased moisture content with vegetation, for example, after 60 days of seeding, water content in soil was 8.33%, 14.33%,15.45% and 16.35% respectively. And air-slake coal polymer was the best one with integrated analysis as follow： the diameter of the particles was in the scope of 20 nm to 60 nm, the anti-press intension of concretion was 5.30 MPa to 16.10 MPa, and the effect of anti-gelation and anti-weathering were significant. Additionally, the function of anti-wind erosion was strong, for that no dust and erosion occurred when the wind blown continuously at 25 m·min^-1 for 30 min and 30 m·min^-1 for 5 min, respectively. Therefore, air-slake coal polymer was the optimum one to provide nutriments, fix sand, preserve water.
