摘要: 试验证明,土地沙漠化生物整治技术能在半荒漠风沙区取得显著的作用和效果。在柠条、毛条、花棒、杨柴、沙木蓼等灌木树种的适生立地上营造防风固沙林,林后3~4年,灌木就可郁闭成林,流动沙丘完全被控制变为固定沙丘;林下植被结构得以改善,优良品种增多,如能合理开发其饲料等用途,还具有十分可观的经济效益。

Abstract: Based on the experiment and observation,it is clear that the biological managemental tecniques expect good results in Yanchi semi-desert area,Ningxia Hui Autonomous Region.Establishing wind break and sand fixed forest on suitable habits with shrub species of Caragana intermedia,Caragana korshinskii,Hedysarum scoparium Fisch,Hedysarum laeve B.fedtsch.,Atrapharxis bracteata A.Los,etc.is an effective method of control land desertification.The shrubery will take shape of forest and the shifting dunes will be fixed in 3~4 years.The vegetation under the shrubery will evolve to a structure predominated by improved species.In addition,there will be considerable economic benefit under reasonable development.

Key words: Semi-desert area, Land desertification, Selection of tree species, Soil moisture dynamics, Regime of sand dune moving
