摘要/Abstract

摘要： 综合性固沙技术在荒漠治理方面有着良好的发展前景。通过研究荒漠苔藓与凹凸棒基高吸水性树脂固沙材料的复配质量比与接种量对苔藓结皮的生长状态与生理特性的影响，探索和优化生物固沙与化学固沙技术相结合的技术途径。结果表明：温度和光照一定时，荒漠苔藓与凹凸棒基高吸水性固沙材料以质量比1∶4复配，以接种量500g·m^-2洒于沙面，所形成的苔藓结皮发育状况最佳。

Abstract: Comprehensive sand-fixation technology has potential and application prospect in desertification control and restoration. The feasibility of combining biological and chemical sand-fixation technology was explored by studying the growth state and physiological characteristics of moss soil crust,mixed with different compounding ratio and inoculum concentration of attapulgite superabsorbent sand-fixation material. The results showed that,on the certain temperature and light intensity,the moss soil crust grows in the best state when sandy-moss,mixed with attapulgite superabsorbent sand-fixation material at a mass ratio of 1:4,was inoculated on the sand at the size of the 500 g·m^-2. The study brings positive effect in promoting the improvement of sand-fixation technology.

Key words: moss soil crust, attapulgite, sand-fixation material, superabsorbent polymers
