青藏高原东北部奖俊埠遗址光释光测年数据

人类对高海拔环境（>2500m）的适应是人类进化和扩散过程的重要里程碑。青藏高原作为世界上海拔最高、面积最大的高原，是开展人类适应极端缺氧环境研究的理想区域。青藏高原东北部甘肃永登县庄浪河畔新发现一处具有连续地层的早期遗址——奖俊埠遗址。2015年和2018年两个年度对该遗址进行系列取样，光释光测年结果显示遗址年代在120-90ka，这是青藏高原目前年代最早的旷野遗址，为青藏高原早期人类活动历史和生存适应研究提供了新的线索。

Human adaptation to high-altitude environments (>2500 m) represents a critical milestone in human evolution and dispersal. The Tibetan Plateau, the highest and largest plateau on Earth, serves as an ideal region for studying human adaptation to extreme hypoxic environments. A newly discovered early site with continuous stratigraphy, the Jiangjunbu Site, was found along the Zhuanglang River in Yongdeng County, Gansu Province, in the northeastern part of the Tibetan Plateau. Systematic sampling was conducted at this site in 2015 and 2018. Optically stimulated luminescence (OSL) dating results indicate that the site dates to 120–90 ka, making it the oldest known open-air site on the Tibetan Plateau to date. This discovery provides new clues for research into the history of early human activities and survival adaptations on the Tibetan Plateau.
