Climate change has a profound impact on ecosystem stability. Recent studies still have insufficient understanding of the response of vegetation to climate change, especially the response of vegetation to short-term climate anomalies. Based on normalized difference vegetation index (NDVI) and the meteorological data, this study conducted a quantitative assessment of the ecosystem resilience and resistance and analyzed the relationship between resistance, resilience and land cover. Furthermore, a new method was developed to identify ecologically fragile regions. The result showed that the resilience and resistance of the Central Asia ecosystem to short-term climate change are generally low. The relationship between resistance, resilience and vegetation cover was nonlinear. If there were too many or too few trees, the stability of the ecosystem was compromised. Ecologically fragile areas were found in transition areas from vegetation to non-vegetation. This study helps to better understand and quantify vegetation resilience and resistance while explicitly taking short-term climate anomalies into account. The results provide more detailed guidelines for strengthening ecosystem management.

气候变化对生态系统稳定性有着深远的影响。近年来的研究对植被对气候变化的响应，特别是植被对短期气候异常的响应认识还不够。本研究基于归一化差异植被指数（NDVI）和气象数据，对生态系统的恢复力和抵抗力进行了定量评估，并分析了抵抗力、恢复力与土地覆盖之间的关系。此外，还开发了一种新方法来识别生态脆弱地区。结果表明，中亚生态系统对短期气候变化的恢复力和抵抗力普遍较低。阻力、恢复力和植被覆盖之间的关系是非线性的。如果树太多或太少，生态系统的稳定性受到损害。在从植被到非植被的过渡区发现了生态脆弱区。这项研究有助于更好地理解和量化植被恢复力和抵抗力，同时明确考虑短期气候异常。结果为加强生态系统管理提供了更详细的指导方针。
