摘　　要：西北干旱区生态系统薄弱,一旦破化则难以恢复,从而研究西北干旱区生态系统恢复机制则具有重要的现实意义。在退化生态系统恢复的诸多方法中,西北干旱区生态系统恢复机制则应更强调的是适应性、可行性原则。以在西北干旱区实施的退牧还草、退耕还林工程为例,通过合理的政策安排,调整和约束人类行为,优化人地关系,以使退化的生态系统得以恢复。The ecosystems in arid area of Northwestern China are fragile and it is very hard if it was destroyed. This means that it is meaningful to study the restoration mechanism of ecosystems in arid area. Among various methods for the ecosystem restoration, those for the restoration mechanism of ecosystems in arid area should be emphasized on the adjustability and feasibility. Taking the projects ＂Returning Grazing Land to Protected Grassland＂ and ＂Returning Arable Land to Forest＂ in the arid areas as the examples, the strategies for the ecosystem restoration were provided.

关 键 词：西北干旱区 生态恢复 退牧还草 退耕还林 机制
