本文论述了冰川平衡线高度的环境意义,并对目前国内外确定冰川平衡线高度的方法进行了评述。根据近年来的野外观测和1960年以来的大量调查资料,确定了天山乌伦其冰川谷1号冰川的最大侧碛高程(MELM),从而确定了现今1号冰川的ELAO。因此,作者修订了ELAO与气候之间的关系的公式。应用该公式对小冰期第二次冰川推进阶段的冰川进行了表征,得到了250aB.P.以前的半定量气候推测结果。
The authors of present paper deal with the implication of the equilibrium line altitude (ELAO) of glacier for environment and review the methods of its identification so far within China and abroad. Finally the authors identified the ELAO for the present No.1 glacier in the U-rumqi glacier valley, Tianshan Mts, China, by determining its maximum elevation of lateral moraines (MELM), based on their field observations in recent years and a study of great amount of the related data surveyed since 1960. As a result, the authors revised the formula for the relationship between the present ELAO and climate. This formula is then applied to characterize the glacier in the stage of second glacier advance during the Little Ice Age and hence the results of semi-quantified presumption of climate prior to about 250a B.P. are obtained.
