本文利用2006年实测水文数据,找出冰川自动气象站气温与冰川融水径流量关系,并根据酒泉气象站与冰川末端气象站气温关系,重建1960～2004年七一冰川融水径流资料.近40多年来,酒泉站气温增加幅度为0.24℃/10a,冰川融水量增加幅度为0.076×106 m3/10 a,冰川融水量随气温增加明显.利用气候突变分析发现,气温发生突变点为1996年,1996～2004年冰川表面年平均气温比1960～1995年间高0.41℃,年冰川融水量1996～2004年比1960～1995年增加了0.41×106 m3(增加26.9%),冰川融水径流量在气候变暖背景下变化显著.

In this paper,the temperature data from 1960 to 2004 in Jiuquan weather station were used to rebuild the streamflow of Qiyi Glacier,with a view to the significant correlation between the air temperature and glacial melt-water streamflow.The distribution and variation coefficients of annual glacial runoff were analyzed.The temperatures of Jiuquan weather station have increased by 0.24℃/10a-1 over the recent 40 years,as a result,the glacial melt-water discharge increased by 0.076×106 m3/10a-1 in the Qiyi Glacier.Analysis of climate Jump shows that,the temperature jump point of Jiuquan is at 1996,the mean surface temperature of the Qiyi Glacier during 1996-2004 increased about 0.41℃ compares to the period of 1960～1995,and the glacial runoff increased about 26.9%(0.41×106m3).
