摘　　要：对白刺属植物的分类、分布、特性以及现状等方面作了系统的整理和总结,以唐古特白刺为例,从资源异质性的角度论述了其生态功能,并指出白刺沙堆的发生和发展机制对土地退化和恢复有重要意义。分析了白刺属植物退化的原因,并据此提出了相应得保护策略,The classification , distribution , characteristics and actuality of genus Nitraria are settled and summarized through systematic studies. Taking Nitraria tangutorum in sand dune as an example, discussed the ecological function from the point of resource heterogeneity,and pointed out that the happening and developing mechanism of Nitraria tangutorurn shrub have important meanings to soil degeneration and comeback. The causation of retrogression is analysed and some suggestions of protective measures are proposed according to it.
