The increased intensity and frequency of extreme climate events (ECEs) have significantly impacted vegetation phenology, further profoundly affecting the structure functioning terrestrial ecosystems. However, mechanisms by which ECEs affect end growing season (EOS), a crucial phenological phase, remain unclear. In this study, we first evaluated temporal variations in EOS anomalies Northern China (NC) based on Normalized Difference Vegetation Index (NDVI) Enhanced (EVI) from 2001 to 2018. We then used event coincidence analysis (ECA) assess susceptibility four (i.e., heat, cold, wet dry events). Finally, examined dependence response background conditions. Our results indicated slight decrease proportion areas experiencing heat (1.10% 0.66% per year, respectively) increase (0.77% year) during preseason period. Additionally, exhibited delaying trend at rate 0.25 days/a study was closely related local hydrothermal conditions, with higher hot drier warmer cold wetter regions. Grasslands, contrast forests, were more sensitive dry, due their weaker resistance water deficits stress. This sheds light how phenology responds across various ecosystems could also provide valuable guide for ecosystem management arid

Abstract Grassland phenology is highly sensitive to climate change. Here, we investigate the spatiotemporal patterns of start (start season (SOS)) and end (end (EOS)) dates growing quantify changes in their climatic controls over arid Central Asian grassland ecosystems during 1982–2015, which may improve model performance by considering shifts primary drivers under ongoing Our results suggest that temperature played a positive role advancing SOS date, with control on getting stronger as preseason conditions become warmer but not drier. For autumn phenology, rapid increase after 1999 combination reductions precipitation jointly contributed shift from delayed advanced EOS. The areas EOS regulated either or have changed between two subperiods. findings dynamic difference spring should be built into phenological models more accurately.
