摘要
自1922年以来,内蒙萨拉乌苏地区不断有'河套人'、'河套文化'和'萨拉乌苏动物群'的化石和遗物发现,从而成为我国北方晚更新世的典型地点。笔者通过最典型的滴哨沟湾剖面的孢粉分析,阐明该区末次冰期的古气候、古环境的变迁。
Salawusu area of Nei Monggol, is the famous ruins of 'Hetao man' and their culture. It is also the native haunt of Salawusu Fauna and the typical site of the late Pleistocene in northern China. By densely sampling and carefully analysing, the authors worked out a beautiful and complete pollen-spore diagram of the Salawusu section, which records in detail the proccess of the vegetational development and the climatic changes of this region since Last Glacial periods, about 60 ka B.P. Accordingly, the last glacial period may be divided into three substages: Early, middle and late substage, corresponding to the pollen-spore zones: Ⅰ,Ⅱ, and Ⅲ. Substages are divided into cold stadials and relative warmmer interstadials, corresponding to subzones of pollen-spore zones. This scheme can be well correlated with that of other regions in China, in Europe, in America and the results of the oxygen isotopic research in deep sea, all over the world.
