Abstract:

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2.34~4.74m/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4381m,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。
