摘　　要：中国西南喀斯特石漠化区域生态系统的退化和恢复受到人为干扰的直接影响,并受到植被、土壤、土壤生物的协同调控。生态环境的脆弱性和持续石漠化,增加了石漠化治理和退化生态系统恢复的难度。采用持续稳定的生态恢复长效措施,减少不合理的生产方式,充分发挥草本植物在生态系统恢复初期的突出优势,重视凋落物对水土保持和生态恢复的促进作用,有利于驱动喀斯特退化生态系统的自然恢复。The ecosystem degradation and ecological restoration in karst rock desertification areas of southwest China are influenced by human factor and coordinated regulation of vegetation, soil and soil organisms. Moreover, the ecoenvironmental vulnerabilities and continuous rock desertification make it more difficult to solve desertification and restore degraded ecosystem. It is conducive to the natural ecological restoration of degraded karst ecosystem by adopting a steady long-term ecological restoration measure, reducing irrational modes of production, taking the outstanding advantages of herbs on the initial stage of ecological restoration and paying attention to the impact of litter on the conservation of water and soil and ecological restoration.
