摘　　要：发生于１０─１１ｋａ左右的新仙女木事件是一次全球性的气候突然变冷事件。目前的有关其成因的各种假说都不能完全解释它的形成机制，本文通过对比世界各地的有关此事件的地质记录，综合评判各种假说，目前关于此事件的成因尚未搞清。现有的知识表明，洋流的改变及与之相伴随的海一气系统的重新调整，对理解此事件及与此类似的气候突发事件具有指导意义。One of the most dramatic climate change events is the Younger Dryas,a return tonear-glacial conditions during～10－11 ka BP. that punctuated the last deglaciation，It be-gan and ended with large climatic shifts that took place very abruptly and globally．Possiblemechanisms that created these abrupt climatic shifts are under intense investigation. Many ofhypothesis are summarized in this paper．Although the cause of the Younger Dryas coolingremains an enigma a general consensus seems to be emerging that，the change of oeean cur-rent，together with the modification and interaction of oceanic-atmospheric system mayprobably be the key to understanding the such analogoues events of sudden climatic changes。
