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.

Key words：Qinghai-Tibet Plateau;Alpine meadow;Degradation;Restoration
