利用IBIS-L地基In SAR系统,在新疆和静县备战铁矿附近的一处山地冰川进行了冰面流动速度连续观测。结果表明,该冰川平均表面流动速度为2.63 mm/h,且在空间上呈现从冰川中上游向下游递增的趋势,但冰川末端的流动速度明显减缓。在观测时间内,冰川运动状态较为平稳,基本处于连续滑动状态。研究结果为揭示冰川基本性质及其动力学机制提供了重要的基础数据,初步验证了地基In SAR技术测量冰川表面流速的可行性及其广阔的应用前景。
Using IBIS-L foundation In SAR system, a mountain glacier near the iron mine was prepared in Hejing county for continuous observation of ice flow velocity. The results show that the average surface velocity of the glacier is 2.63 mm / h, which shows an increasing trend from the upper reaches to the lower reaches of the glacier, but the flow velocity at the end of the glacier slows down significantly. During the observation period, the state of glacier movement is relatively stable, and is basically in a continuous sliding state. The results of the study provide important basic data for revealing the basic properties of glaciers and their kinetic mechanisms. The feasibility of the ground-based In SAR technique for measuring glacier surface velocities and its broad application prospects are preliminarily verified.
