| 摘 要： | 毛主席曾经谆谆教导我们:“今天的中国是历史的中国的一个发展;我们是马克思主义的历史主义者,我们不应当割断历史”。研究社会应是这样,研究自然界也应是这样。因为现今的自然界是历史的自然界的最新阶段,如果我们要认识和改造今天的自然界,甚或企图去预测它将来的发展,那么我们就必须重视研究自然界的发展史,尤其是应注重研究与现今自然界密切相关的第四纪的发展史。

| Abstract: | Basing upon the research results it may be suggested that Beijing Plain was characterized by forest and steppe with pine, spruce, fir and broad-leaf species in Late Pleistocene (dated by radiocarbon at 29300 ± 1350) and by cold climate. The average annual temperature was about 4℃. This period can be correlated with the Wisconsin glacial stage of North America, Wurm glacial stage of Europe and Daili glacial stage of China. Since then, the temperature rose and the geologic time has stepped into Holocene. |
