摘　　要：青藏高原高寒草甸受气候变化和人类活动的影响,发生了严重的退化。从土壤、土壤微生物和植物群落3个方面对近年来青藏高原退化高寒草甸的研究进展进行梳理,对近年来退化草地修复的研究进展从草地补播、划破草皮、无纺布覆盖、围栏封育、施肥及政策影响等方面进行了综述,在此基础上对未来的研究方向进行了展望。The alpine meadow on the Qinghai-Tibet Plateau has been seriously degraded due to climate change and human activities. This article summarizes the research progress of degraded alpine meadow on the Qinghai-Tibet Plateau in recent yearsfrom three aspects: soil, soil microorganisms, and plant communities. The research progress on restorationof degraded grassland restoration in recent years has been reviewed in terms of grassland reseeding,cutting turf,non-woven mulching,enclosure,fertilization,and policy impact,providing a prospective design and overall plan for restoring the degraded grassland.
