摘要
我国是世界上受荒漠化影响最严重的国家之一,土地荒漠化每年造成的直接经济损失上百亿元,严重制约着经济的可持续发展。化学固沙技术是荒漠化治理的一种重要途径,其优点是成本低,施工简便,见效快。高分子材料是化学固沙的主要原料。综述了石油产品类、合成高分子类、生物质资源类固沙剂,以及高吸水树脂保水剂在沙漠治理中的应用。
Desertifieation that causes tens of billion yuan of economical loss annually, which restricts regional continual development severely has been a nationwide problem. Chemieal sand fixation is an important method of desertifieation control due to its low eost, effieieney and suppleness, for which polymer is the main material. The applieations of several kinds of sand fixation agents ineluding petroehemieal, synthetie polymer, biomass, and superabsorbent polymer for the desertifieation control were summarized.
