Quantifying Vegetation Vulnerability to Climate Variability in China

Climate variability has profound effects on vegetation. Spatial distributions of vegetation vulnerability that comprehensively consider sensitivity and resilience are not well understood in China. Furthermore, the combination cumulative climate a one-month-lagged autoregressive model represents an advance technical approach for calculating sensitivity. In this study, spatiotemporal characteristics to were investigated at seasonal scales. Further analysis explored spatial different regions. The results showed distribution pattern exhibited heterogeneity spring, values approximately 0.9 mainly distributed northern Xinjiang Inner Mongolia, while low scattered Yunnan Province central region East highest proportion severe was observed subhumid zone (28.94%), followed by arid (26.27%). summer autumn, proportions humid zones higher than those other zones. Regarding types, found sparse seasons, slight croplands seasons. addition, with high is prone change Northeast Southwest Although ecological restoration projects have been implemented increase cover China, region. Most grasslands, which concentrated Qinghai–Tibet Plateau, had vulnerability. Vegetation areas likely be degraded highly vulnerable Plateau could function as warning signals degradation. Knowledge patterns will help provide scientific guidance regional environmental protection.
