采用玉龙雪山白水1号冰川2011年6~9月的高精度GPS实测数据,对白水1号冰川的运动速度进行了探索性研究,并与其他数条典型冰川作了对比分析。结果表明,与北半球典型大陆性冰川相比,玉龙雪山白水1号冰川运动速度明显偏快,介于2.34~4.74 m/月之间,是同规模大陆性冰川的月运动速度的6~10倍,有独特的海洋性冰川运动特征。与藏东南同一类型的帕隆94冰川相比,玉龙雪山白水1号冰川运动速度约为其一半,这说明海洋性冰川的运动速度与规模成正比。同时,白水1号冰川末端平均海拔为4 381 m,近10年几乎保持了相同的退缩速度,说明在当今气候变化背景下,白水1号冰川对气候变暖的响应程度相同。

This paper is dedicated to gauging velocities using high resolution GPS during the period from June to September in 2011, making explorative research and comparatively analyzing with other typical glaciers in Baishui No.1 Glacier, which is a representative maritime glacier in Mt.Yulong. It is suggested in the result that special characteristics of velocity exist in Baishui No.1 Glacier, which revealed obviously as its style, monthly range from 2.34 m to 4.74 m, 6-10 times faster than other kinds in the same area. Comparatively, the velocity of Baishui No.1 Glacier is half of that in Palong Glacier No.94, which demonstrates that velocities are proportional to their scale. In addition, the terminus of Baishui No.1 Glacier evenly elevated 4381m above sea level, retreating of an identical rate over the past decade, which is the same indicator as the past 10 years’ under the background of climate change.
