摘　　要：青藏高原是世界上最高、最年轻的高原,它对北半球的气候变化有重大影响。全新世是与人类进化、人类文明形成最密切的时期。分析、总结了青藏高原全新世的气候环境变化的研究成果,并对这些成果进行讨论。高原的全新世大暖期来临于10kaBP,鼎盛期为7-6kaBP,大暖期时,高原植被、森林扩大,泥炭发育,湖面上升,夏季风增强。大约在5kaBP,高原气候由暖湿向冷干转变。Qinghai-Tibetan Plateau is the highest and the youngest one in the world. It strongly affects the climatic shift in the north hemisphere. Holocene is most closely related to human evolution and human civilization. This paper deals with the study results of Chinese scientists on the Holocene climate fluctuations in the Tibetan Plateau. Holocene megathermal event began at about 10kaBP. The maximum megathermal stage took place about 7～6kaBP. During the megathermal phase, vegetation and forest extended, peat formed, lake ascended, the summer monsoon strengthened. At about 5kaBP, the climate changed from warm-humid to cold-dry.
