摘要
本文概要地回顾了第四纪的主要气候事件，包括万年尺度的冰期－间冰期旋回，千年尺度的Ｈｅｉｎｒｉｃｈ事件，Ｄａｎｓｇａａｒｄ－Ｏｅｓｃｈｇｅｒ旋回和新仙女木事件及百年尺度的小冰期。简述了这些事件特征和时限以及产生的背景。指出这些事件大部分首先发现于冰川和深海沉积物中，且集中在北半球的高纬度地带。湖泊沉积物是研究古气候突变事件及古季风变化的重要信息载体之一，今后应进一步加强研究。
This article has a brief review on the main climatic events occurred during the Quaternary, such as the orbital scale glacial-interglacial cycles millenium scale Heinrich events, Dansgaard-Oeschger cycle and Younger Dyras. The characteristics, time intervals and the mechanisims were reviewed. Most of those events were found in the glacial and deep sea sediments, mainly occurring on the high latitudes of the Northern Hemisphere. Lacustrine deposit is an important archive in documenting the paleoclimatic abrupt events and the paleomonsoon circulation variation, which should be paid more attentions in the future.
