氣候變化與清代以來雲南的鼠疫流行

Climate changes and the epidemic of plague in Yunnan Province since Qing Dynasty

影響清代以來雲南鼠疫流行最關鍵的因素是氣候。在雲南，只有當社會出現動盪甚至戰亂時，社會因素才超越氣候因素，成為影響鼠疫的罪魁禍首。傳統時代雲南銅礦開發、鹽業開發、茶葉貿易等最重要的產業，對於鼠類生態系統的擾動，並不如人們想像中的那麼大。

The most critical factor in the epidemic of plague in Yunnan Province since Qing Dynasty was climate. Social factors would beyond climate factors and become more important in plague epidemic only when the social unrest and war occurred. As the most three important industries in traditional times of Yunnan, the copper exploitation, salt industry development and the tea trade didn’t play so important role as people imaged in the disturbance of the mice rodents ecosystem.
