The ability of ecosystems to resist and recover from external disturbances is declining due to climate change, increased frequency of disasters, and intensified human activities. Global vegetation resilience is considered to be at risk of being lost. The sensitive and fragile Tibetan Plateau (TP) has experienced changes in climate and management patterns over the past five decades, but due to the complexity of defining resilience, there is still no unified understanding of the spatial patterns and long time‐series trends of resilience on the TP. In this study, we introduce the method based on critical slowing down, making it possible to clarify the spatial distribution and temporal dynamics of resilience on the TP. The results show low resilience on the northeastern and southwestern edges of the TP and in the Three River Source region. The area experiencing resilience loss is approximately 1.16–1.44 times larger than the area of gain. Vegetation resilience on the TP has exhibited a declining trend, with the rate of decline after 2014 being more than double that of the preceding period. Factors such as elevation, vegetation type, and hydrothermal condition significantly influence the spatial and temporal patterns of resilience. These findings improve our understanding of vegetation resilience on the TP and its ecosystem vulnerability. We also recommend that ecological restoration efforts be maintained and regularly assessed.

青藏高原植被恢复力加速下降


由于气候变化、灾害频率的增加和人类活动的加剧，生态系统抵抗外部干扰并从中恢复的能力正在下降。全球植被恢复力被认为面临丧失的风险。过去五十年来，敏感而脆弱的青藏高原 （TP） 经历了气候和管理模式的变化，但由于韧性定义的复杂性，对青藏高原韧性的空间格局和长期序列趋势仍未形成统一认识。在本研究中，我们介绍了基于临界减速的方法，从而可以阐明 TP 弹性的空间分布和时间动态。结果表明，青藏高原东北和西南边缘以及三江源地区的复原力较低。经历弹性损失的区域大约是增益区域的 1.16-1.44 倍。青藏高原植被恢复力呈下降趋势，2014 年后下降速度是前一时期的两倍多。海拔、植被类型和热液条件等因素显着影响复原力的空间和时间模式。这些发现提高了我们对 TP 植被恢复力及其生态系统脆弱性的理解。我们还建议维持生态恢复工作并定期评估。
