摘要： 通过整理历史文献中有关天山北麓东部地区18世纪中后期的相关记载,发现1757—1774年的历史文献记载了巴里坤作物物候和霜雪事件,根据物候学原理,确认1757—1774年巴里坤存在有温度升高的现象。并根据同时期历史文献中乌鲁木齐的冷暖感应记载,认为1757—1774年的温度升高发生在整个天山北麓地区。结合已有的树木年轮研究成果,并根据当时的人文社会背景进行分析,进而从更宏大的时空尺度上认识此次温度升高在历史文献记载中的具体内涵,认为历史文献记载的1757—1774年温度升高是相对于18世纪10—20年代,而非30—50年代。根据历史文献重建温度变化,必须结合文献形成的历史背景,因为同时期的人文社会背景,会影响到历史文献记载的可靠性。

Abstract: In this paper,a lot of historical documents were collected to restruct temperature change in the eastern area of northern foot of Tianshan Mountains during the mid-late 18th century.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 Therefore,the historical documents recorded a warm period in the northern foot of Tianshan Mountains in AD 1757-1774. Combining with the existing research results by tree-ring and the social background, temperature rise recorded by the historical documents was analyzed and understood essentially.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 Since the social background would influence the reliability of historical documents, is is essential to focus on it to restruct the temperature change according to the historical documents.

Key words: temperature change, historical documents, tree-ring, northern foot of Tianshan Mountains, 18th century
