【摘要】 青藏高原东南部地区是广义横断山区的重要组成部分，其地形、地貌、气候和生态环境多元复杂，生物资源丰富多样，自古以来就是连接青藏高原、云南高原、四川盆地，以及南亚和东南亚地区的重要区域，也是青藏高原与周边地区人类迁徙和扩散的重要通道。现有考古材料显示，该地区自中更新世晚期以来的一系列旧石器时代遗存在剥片技术体系和工具生产策略等方面均表现出了显著的多样性和复杂性面貌，其形成机制可能与该地区多元复杂的自然地理环境息息相关，也在一定程度上反映出该地区早期人群构成和古人类演化、扩散的复杂性。对青藏高原东南部地区旧石器时代不同阶段石器技术的系统梳理和比较分析，为高原及周边地区古人类演化和扩散问题的研究提供了重要的线索和启示。更多还原

【Abstract】 The southeastern region of the Tibetan Plateau, as a key part of the broader Hengduan Mountains, is distinguished by its diverse terrain, geomorphology, climate, and ecological environment, and is home to rich and varied biological resources. Historically, this region has served as an essential corridor connecting the Tibetan Plateau, Yunnan Plateau, Sichuan Basin, and the regions of South and Southeast Asia. It has also been a key route for human migration and dispersal between the Tibetan Plateau and adjacent areas. The Paleolithic remains in this region, dating back to the Late Middle Pleistocene, demonstrate significant diversity and complexity in core flaking technologies and tool production strategies. This technological variation may be closely tied to the region’s complex and heterogeneous natural environment, reflecting the intricate dynamics of early human population composition, evolution, and dispersal in the area. A systematic review and comparative analysis of lithic technologies from different Paleolithic stages in the southeastern Tibetan Plateau offers valuable insights into the study of early human evolution and dispersal across the plateau and its neighboring regions.更多还原
