英文摘要：

Local records and local archives appeared in large numbers during the Ming and Qing Dynasties, which greatly improved the＂ resolving power＂of the elements of regional environmental history in this period. Taking the environmental history of the Jialing River basin as an example, the records of prefectures , administrative divisions, counties and governmental departments in Sichuan compiled during the Ming and Qing Dynasties and the well preserved Nanbu Archives and Ba County Archives keep the environmental history information that is very precious and seldom used , such as climate change, distribution and changes of wild plants and animals. The local literature records also show that three abnormal cold stages emerged in the Jialing River basin during the Ming and Qing Dynasties. According to the local literature , we can clarify forest distribution and kinds of forest trees in the Jialing River basin .
