摘要: 阿尔泰山区是我国最北部的冰川分布区,人烟稀少,气象观测台站不多,记录年代只有一、二十年,最长也不超过30年。这对研究冰川与气候的关系造成了一定困难。但是,阿尔泰山区森林分布很广,甚至在一些冰碛上也生长有良好的树木,有利于借助树木年轮气候学弥补气象资料的短缺。

Abstract: Through analysis of tree ring data, the variations of cold and warm climate in the last 300 years,and of dry and wet in the last 180 years in the region of Mts. Altay were found out. Totally four colder and four warmer periods as well as dry and wet stages were identified and their influences on variations of glaciers in the last 180 years in the same region were analysed. We found that glaciers advanced greatly in 1853-1888, and retreated in other years. However, in the 70’s of this century, the climatic condition is favorable for glacial advance.
