中国第四纪大冰期问题争论已久。实践证明,李四光教授划分的四次冰期是正确的。近年的资料表明,鄱阳冰期以前还有冰期和冰缘期存在,补充了李四光教授晚年时提出的意见。同时,由于气候地层原则的推广应用,冰期和间冰期对我国第四纪地层划分所起的作用,也日渐显现出来了。本文简要报道这两方面的成果。

Quarrels of Quaternary Great Ice Age in China have long been debated. Practice has proved that Professor Li Siguang division of the four glaciers is correct. Recent data show that there were still glacial and ice-edge periods before the Poyang glacial period, which supplemented Professor Li Siguang’s advice in his later years. At the same time, due to the popularization and application of climate stratigraphy, the role played by glacial and interglacial periods in the stratigraphic division of Quaternary in our country also becomes increasingly apparent. This article briefly covers the results of these two areas.
