| Paleoanthropologic Evolution and Paleoclimatic Change in Guilin Area, Guangxi |
| Guilin was an area of human activity in ancient time. Statistics of paleoanthropologic cave relics show that the upper limit of the human activity can be traced back to 7000 a B P in northern Guilin. After that, primitive men left caves, and their prehistoric culture also changed. What drove primitive men to leave caves and change their custorns? This is a problem that has long puzzled archaeologists. This paper has studied characteristics of the cave relics and paleoclimatic records of speleothem and pollen and discussed changes of paleoclimate driven by monsoon. On such a basis, a conclusion is drawn that living conditions of the primitive men might have been disturbed by some abrupt events and the changing time sequence of the nonsoon since Holocene. About 7000 years ago, the primitive men were forced to leave the caves. The reason is as follows:At that time, there existed an optimal period of Middle Holocene and the climate of southeast China was mostly affected by the summer east monsoon, and the rainfall in Guilin area increased, which led to the elevation of the water level of underground rivers and flooding of the caves. |
