青藏高原高寒草甸退化与修复研究进展

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。

Abstract：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.
