祁连山七一冰川观测结果表明, 2001/2002年度和 2002/2003 年度冰川物质平衡分别为-810mm和-316 mm水当量, 冰面出现显著的减薄状态. 和过去的观测结果相比较, 20 世纪 70 年代为较大的正平衡, 年平均为360 mm水当量; 80年代年平均为4 mm水当量, 基本接近零平衡状态. 到近两年亏损强烈, 为所有观测资料中负平衡值最大的年份, 零平衡线也达到最高位置. 物质平衡出现较大的负值和零平衡线位置升高的状况, 强烈反映了祁连山冰川对气候变暖过程的响应. 如果气候变暖趋势继续, 冰川物质平衡负值将增大、冰面减薄和雪线的升高, 冰川将继续呈现萎缩状态.
The observation results of the Qiylian glacier in the Qiyi Glacier show that the mass balance of glaciers in the years 2001/2002 and 2002/2003 are -810mm and -316mm water equivalent, respectively, with significant thinning on the ice surface.Compared with the past observations, 70 years for the larger positive balance, with an average annual 360 mm water equivalent; the average annual in the 1980s 4 mm water equivalent, close to zero equilibrium, the strong loss in recent years, for all observations the largest negative balance Year, the zero balance line also reached the highest position.Physical balance appeared a greater negative value and zero balance line position increased, strongly reflects the Qilian glacier response to the warming process.If the warming trend continues, the glacier material Negative balance will increase the ice thinning and rising snow line, the glacier will continue to show shrinking state.
