上新世以采的中国自然地理环境和中国古人类的进化

本文通过把中国古人类的进化摆到中国这一特定的地理区域、特定的自然地理环境中去作联系的考察,提出如下几点看法:1.中国是世界上很早就为人类所居住的地区之一,受自然地理环境的影响和制约,中国古人类主要生存于自然条件较好的东部季风区域;2.古人类在中国境内主要是由南向北、进而向东北方向扩散和分布;3.中国最早的古人类可能是外来的,可能是从中国南部边境进入中国境内的。

PHYSICAL ENVIRONMENT SINCE PLIOCENE AND THE EVOLUTION OF FOSSIL MAN IN CHINA

Through the investigation of the evolution of fossil man in the context of physical environment since Pliocene in China, this paper puts forward some suggestive ideas:1. The main characters of physical environment since Pliocene in China are the gradual formation of three great topographic steps from west to east, the climatic changes, and the beginning of areal differentiation into three natural realms (Eastern Monsoon Area, Northwestern Arid Area, Tibetan Frigid Area), which had great effect on the evolution of fossil man in China.2. Influenced and restricted by the physical environment, the fossil man of China lived mainly in the Eastern Monsoon Area of which the physical conditions were the very best among the three natural realms.3. The general trend of distribution of fossil man was from south to north, then furthere to north-east in China.4. The earliest fossil man in China probably had came from other parts of the world, entering China from the south.
