중국 선진시기의 기후 환경 기후 변화와 코끼리 벼 인구 분포의 상관관계 탐색

Abstract

Two contradictory views exist on the climatic environment of the Yellow River basin during the Pre-Qin period (BC2070-BC221). First, it was friendly to human life. Second, it was unfriendly to human life. I support the former. I summarized the results of the research in each of the four fields independently of each other and presented them as proof of the former. First, studies by climatologists showed that in the Pre-Qin period, temperatures in the Yellow River basin were about 2℃ higher than today. Second, according to animal archaeologists, tropical elephants lived in the north. This suggests that the climate in the Yellow River basin was warm and humid, not cold. Third, according to research by plant archaeologists, paddy rice, which grows mostly in the tropics today, was cultivated in the Yellow River basin during the Pre-Qin period. This suggests that the temperatures in the Yellow River basin at that time were not only higher than they are today, but also more rainfall. Fourth, demographers have found that during the Pre-Qin period, people lived more in the Yellow River basin than in the Yangzte River basin. The reason is that the north has a better climate and more varied and richer food than the south.
