摘要: 根据1956年以来天山昆马力克河麦茨巴赫冰川湖突发性洪水记录,分析了该冰川湖突发性洪水与气候要素特别是气温间的关系,认为冰川湖迅猛排水受制于年内气温波动引起的伊力尔切克冰川消融期与消融强度的变化,该冰川湖迅猛排水时的洪峰流量与总洪水量具有逐年增加的趋势,这种增加趋势与天山地区区域性温暖化有密切的关系。

Abstract: The relationship between jokulhlaup from the Lake Mertzbakher in the Tianshan Mts. and climatic parameters, esp. air temperatures, is analysed based on the long-term records of the outburst floods since 1956. It can be concluded that monthly air temperature variation, which gives rise to the change of ablation duration and rate of the South and North Inilchek Glaciers, play an important role in the fluctuations of the water level and the drainage of the Lake Mertzbakher. A general increasing trend has been prevailed in the temporal variation of peak and total discharges of the jokulhlaup floods of the lake. Such an increasing trend is well coincided with the regional warming in the Tianshan Mountains during the last few decades.

Key words: Lake Mertzbakher, jokulhlaup, regional warming
