| Abstract: | The Qaidam Basin is one of the main areas where the desert of Qinghai -Xizang Plateau distributes. According to the environment records and the age of stratigraphy in Xiaxitai section in southeast part of Qaidam Basin, this paper has concluded that the desert development, formation of the cold-dry climate, evolution of natural environment and their reverse changes occurred frequently since the late glacial. In eolian sand de posits, the Younger Dryas event clearly appears, which manifests that was a dry-cold cli matic period. Now there are two different opinions about the climatic effect of Younger Dryas. According to the predecessors' research and the field work of the authers, it is con sidered that the Younger Dryas event not only exists in different climatic zones in China,but also manifests the unitary dry-cold climatic effect. |
