摘要
围栏封育、机械沙障固沙和人工植恢复措施是当前沙化草地恢复治理的主要手段。将机械沙障方法与人工植被有机结合的使用方式应用更广。目前国内外针对沙化草地退化机理,植被恢复技术措施,恢复治理模式示范与推广等方面研究较多;关于人工种植被对沙化草地的适应机理,根际土壤微生物学特性对植被恢复的响应机制等方面研究相对薄弱。未来研究的重点方向是探索兼顾生态效益和经济效益的植被恢复技术,特别是根据不同地区沙化草地的退化特征,因地制宜开展多学科交叉集成的植被恢复综合治理模式研究。
The main sandy grassland control methods include enclosure, sand--fixation with mechanical sand barrier and artificial vegetation restoration. The combination of sand--fixation with mechanical sand barrier and a- daptable plant is one of the most important means of restoration and control for sandy grassland. There is less re- search on adaptation mechanism of adapted plants to sandy grassland, on response mechanism of rhizosphere soil biological characteristics to sandy grass restoration, further research should be carried out on vegetation restora- tion measures, recovery effects and restoration mechanisms. Future research should be focused on exploring vege tation restoration models with ecological and economic benefits. Extensive studies on integration of comprehensive treatment technology should be carried out in sandy grassland according to their different degradation characteristics.
