中文摘要	利用草浆造纸厂制浆废液经化学改性后制备的新型固沙材料进行了相关野外固沙实验.对3年生固沙群落(主要固沙植物有沙米(Agriophyllum squarrosum L.)、沙蒿(Artemisia desertorum Spreng.)等)进行的野外生态学研究表明:(1)木质素固沙新材料不仅可以快速有效地固定"沙进入退"地区的流动沙丘.而且可以结合植树种草,使沙丘迅速绿化.(2)固沙新材料形成的"沙结皮",节水保墒功能明显,有利于沙生植物成活并最终形成稳定群落.(3)固沙新材料结合沙生植物沙米、沙蒿等固沙后,土壤有机质和全氮增加明显,有利于土壤肥力的增加,可进一步促进植物的生长.(4)与传统的"草方格"固沙技术相比,木质素固沙新材料的使用可以促进地衣结皮快速形成,有利于土壤改良.
英文摘要	This paper presented the preliminary results of desertification control in the field a new sand fixation material,which was made from straw pulping black-liquor.The field ecological measurement was conducted in a three-year old sand fixation community dominated by Agriophyllum squarrosum(L.) Moq.,and Artemisia desertorum Spreng..The results showed the lignin-based sand stabilization material(LSSM) can not only fix the fugitive dune but also make it vegetative fast since the arenaceous plants can be planted and grew well simultaneously with the LSSM implementation.It was found that the fixation shell formed by LSSM protected the soil water from evaporation effectively,and was beneficial to the plant growth and to the formation of stable community.As arenaceous plants community constructed,the organic matter and total nitrogen in the upper-level soil was increased significantly.It stimulated the increase of soil nutrition and consequently the plant growth.Compared with the traditional sand fixation method known as "straw-grid" technique,the utilization of LSSM speeded up the formation of microbiological-shell and the soil amelioration as.
