中文摘要	土地荒漠化是当今世界最严重的生态环境问题之一。采用石膏为主凝固材料,通过合理添加辅助材料,研究各辅助材料对固沙材料保水性能的影响。试验表明:保水剂、木屑、SDS均有利于提高材料保水性能,沙粒掺量为30%时材料保水性能最好。以固沙材料保水率为主要评价指标,当沙粒掺量为30%、保水剂掺量为4%、木屑掺量为8%、SDS掺量为0.3%时,固沙材料保水性能最好,此条件下保水率为79. 24%。该固沙材料对环境无污染,保水性好,适合植物生长,在沙漠治理方面具有广泛应用前景。
英文摘要	Desertification is one of the most serious ecological environment problems in the world. In this paper the effects of different additives on water retention capacity of gypsum based sand-fixing material were investigated by using gypsum as solidification material and adding several additives. The results show that : water-retaining agent,sawdust and SDS are conducive to improve the water retention capacity of material. When the sand content of 30%,the water-retention capacity of material is best. Using Water retention as the main evaluation index of sand-fixing material,the obtained best water retention is up to 79. 24% under the sand content of 30%,water-retaining agent dosage of 4%, sawdust content of 8%, and SDS content of 0. 3%. The sand-fixing material has no pollution to the environment, good water retention and suitable for plant growth,therefore, it will have a wide application prospect in the desert governance.
