| 摘 要： | 国际地圈─生物圈计划（ＩＧＢＰ）的中心议题之一就是研究过去的全球变化（ＰＡＧＥＳ），而对过去短期气候突变事件特别是对末次冰期─间冰期过渡时期的ＹｏｕｎｇｅｒＤｒｙａｓ事件的研究更受全球变化研究者的关注．然而，到目前为止，对ＹｏｕｎｇｅｒＤｒｙａｓ的成因及是否为全球性事件等问题，依然争论不休。本文即是对近年来国际上对此事件研究的综述。

| Abstract: | One of the focuses of the International Geosphere-Biosphere Programme(TGBP)is the study of the Past Global Change(PAGES), especially the study of the Younger Dryas episode which existed during the last glacial-to-interglacial transition. However the cause of the Younger Dryas and its global climatic significance still remains enigma. The purpose of this paper is to review the recent reports of this event from the different parts of the world. |
