| 英文摘要 | Understanding vegetation responses to climate change is crucial for evaluating ecosystem resilience in high-altitude regions. This study presents a high-resolution Holocene pollen record (similar to 9700 years) from XingCo Lake in the Zoige Basin, northeastern Tibetan Plateau. We conducted pollen analysis, biome reconstruction, and diversity assessment. Key findings include: 1) Pollen records from the Zoige Basin showed a consistent long-term trend of forest decline since the mid-Holocene, with multiple abrupt vegetation shifts. 2) After excluding Cyperaceae pollen, we observed a marked collapse of the Holocene vegetation optimum around 3.5 cal ka BP, aligned with transitions across the eastern Tibetan Plateau. 3) A notable shift in vegetation richness occurred around 2 cal ka BP under stable vegetation and minimal human impact, coinciding with a decoupling of temperature and moisture, and rising temperatures coupled with declining humidity, fostering increased palynological richness. These results suggest that the past vegetation-climate interactions in the eastern Tibetan Plateau and provide a valuable reference for modeling future vegetation responses in alpine ecosystems. |
