Clarifying the response of plant phenology to drought duration is helpful for accurately interpreting and predicting carbon sinks in ecosystems. Based on different phenological periods dominant species Stipa krylovii monthly, seasonal, semiannual time scale typical steppe Inner Mongolia from 1983 2018, results revealed that (1) start growing season (SOS) was characterized by an advance–delay–advance pattern, heading stage (HOS), flowering (FOS), end (EOS) all showed consistent advanced trends, which provided additional insight into conclusions previous studies found SOS arid semiarid regions. (2) The mechanism timing not consistent. Among mechanism, delayed because January–February at scales but April scales. HOS/FOS June–July scales, EOS August–September (3) More importantly, SOS, HOS, FOS, were affected predrought its persistence, effects greater closer occurred. (4) At monthly scale, droughts January, June, August critical affecting HOS/FOS, EOS, while seasonal February, June–July, September EOS. this study enrich our understanding how affects periods, providing a basis improving models.

Drought events occur frequently, but the impact of drought on plant autumn phenology, i.e., End growing Season (EOS), has not been thoroughly studied. Considering that cumulative and lagged effects plants. In this study, we quantified two EOS in China. Our results indicated affected 39.5% 70.1% plants China over past decades. Two short timescales (2- to 4-accumulated month 1- 5-lagged month) largely first months advanced EOS, while fifth before caused overcompensate for growth delayed senescence. At biome level, forests were more resistant than grasslands shrublands. From perspective water balance gradient, was significant humid regions, it found increased loss exacerbated shortened response time. study reveals phenology provides insights into predicting future vegetation patterns under global change.

As a measure of the accumulated heat deficit during growing season transition, cooling degree days (CDDs) play crucial role in regulating vegetation phenology and ecosystem dynamics. However, systematic analyses CDD trends their driving mechanisms remain limited, particularly high-altitude regions where climate variability is pronounced. This study investigated spatiotemporal CDDs from 1982 to 2022 alpine grasslands on Qinghai–Tibetan Plateau (TP) quantified contributions key climatic factors. The results indicate that lower values (<350 °C-days) were predominantly found warm, arid regions, whereas higher (>600 concentrated colder, wetter areas. Temporally, area-averaged exhibited significant decline, decreasing 490.9 °C-days 495.8 at rate 3.8 per year. Elevation plays critical shaping patterns, displaying nonlinear relationship: decrease as elevation increases up 4300 m, beyond which they increase, suggesting transition global climate-driven warming elevations local environmental controls elevations, snow–albedo feedback, topographic effects, atmospheric circulation patterns regulate temperature Tmax was identified dominant driver variation, above while radiation showed consistent positive influence across elevations. In contrast, precipitation had limited spatially inconsistent effect. These findings emphasize complex interactions between elevation, temperature, radiation, trends. By providing long-term perspective variations drivers, this enhances our understanding vegetation–climate ecosystems. offer scientific basis for modeling late-season phenological changes, resilience, land-use planning under ongoing change.
