Abstract In this paper,a lot of historical documents were collected to restruct temperature change in the eastern area of northern foot of Tianshan Mountains during the mid-late 18th century. There were abnormal frost dates and snow falls in Barkol,and the documents showed temperature rise in AD 1757-1774. Furthermore,some perception records on warm explained the same rise in the Urumchi. Therefore,the historical documents recorded a warm period in the northern foot of Tianshan Mountains in AD 1757-1774. Combining with the existing research results by tree-ring and the social background, temperature rise recorded by the historical documents was analyzed and understood essentially. As a matter of fact,the rise was relative to the 10-20s of the 18th century,not to the 30-50s. Since the social background would influence the reliability of historical documents, is is essential to focus on it to restruct the temperature change according to the historical documents.
