利用2006年8月1日-9月30日的实测水文数据,对“七一”冰川融水径流产汇流特征进行了分析,并揭示出该冰川日消融特征.通过对冰川融水量的估算以及径流模数的计算,并与过去的观测结果进行对比,表明近些年来“七一”冰川消融强度和消融量都在增大,而且2006年消融量为近几年观测的最大值.虽然不同年份消融量不一样,但“七一”冰川总的趋势是一直处于萎缩状态,随着全球变暖,“七一”冰川的萎缩可能将继续下去.通过对设立在沿冰川下游方向两个不同的水文断面进行对比分析,结果表明“七一”冰川融水径流在向下游运动过程中有部分水入渗为河谷潜流,观测期内两个相距不到2 km的水文断面间渗漏损耗占近1/3左右.
Based on the measured hydrological data from August 1, 2006 to September 30, 2006, the runoff producing characteristics of runoff from the “July” glacier melt runoff were analyzed and the daily digestion characteristics of the glacier were revealed. Estimation and calculation of runoff modulus and comparison with the past observations show that in recent years the melting strength and ablation volume of the “July” glacier are increasing, and the ablation volume in 2006 is the largest observed in recent years Although the ablation quantity is different in different years, the general trend of glaciers in the “71” glacier has been shrinking all the time, and as the global warming, the shrinkage of the “71” glacier is likely to continue. The results of comparative analysis on two different hydrological sections along the downstream of the glacier show that part of the infiltration of water into the “Qiyi” glacier melt runoff is valley underflow during the downward movement. During the observation period, Leakage loss between hydrological sections of 2 km accounts for nearly 1/3.
