摘要: 阐述晚更新世以来青藏高原东北部古土壤的形成和发展规律,确立了晚更新世末次间冰期、晚更新世末期、全新世高温期三个古土壤发生时期的气候、植被、土壤和自然地带的基本状况,讨论了古土壤和高原隆起的关系.

Abstract: Based on field investigations, indoor analyses and 14C dating,this paper discusses the laws of the formation and development of the paleosols in the northeast region of the Qinghai-Xizang Plateau since the Late Pleistocene. The author establishes basic condi-tions of calimate,vegetation,soil and natural zones during the three periods in which the paleosols were formed,i. e. the last interglacial stage of the Late Pleistocene,the last stage of the Late Pleistocene and the high temperature stage (Megathermal) of the Holocene. Finally,this paper discusses the relationship between the paleosols and the up-lift of the Qinghai-Xizang Plateau.
