中国南方第四纪哺乳动物群所反映的自然环境变迁

<正> 现代哺乳动物的地理分布,显示出世界各大陆的动物区系同地球上气候分带是密切相关,根据我国现代动物区划(郑作新、张荣祖,1959),可将全国分二界,七个基本区,最主要是东洋与古北二界。南方地区可以划分为西南、华中及华南三亚区,这三亚区基本上是属于东洋界。一些属于东洋界的属种,仅分布于长江以南地区,而华北地区分布很少或

THE LIVING ENVIROMENT OF THE QUATERNARY MAMMALIAN FAUNAS IN SOUTH CHINA

The Quaternary mammalian faunas of South China include the following: Late Pleistocene fauna Ziyang Liujiang Maba Middle Pleistocene fauna Yenjiangguo Bumal Guanyingdong Eary Pleistocene fauna Gaoping Liuceng Yuanmou It explicates the physical environment was stable during the Quaternary. Though the climates there happened certain undulation, it was still of tropical and subtropical. During the Quaternary, when the climate changed in the whole world, the same effect produced in the South China, it seems that the change did not effect the mammals. This is possible that the South China located low latitude area, so that during the glacial age, the effect was not as much as North China. So the faunas of South China did not change as much as North China.
