摘　　要：测定南极冰川的流速,对于研究南极冰雪物质平衡、南极环境变化及其对全球环境的影响和极区航行有重大意义。本文论述了利用多时相卫星遥感影像监测冰川变化的原理和方法,通过对英格里特-克里斯泰森海岸不同时期的遥感影像进行几何纠正和配准及叠加处理,测量和计算出极记录冰川的平均流速,并对它们的变化特点进行了初步的分析和评价。Measurement of ice velocities of the Antarctic glaciers is very important significance for studies on the Antarctic ice and snow mass balance, the polar area environment change and its influence on the global environment. This paper discusses the principles and methods of monitoring the glacial changes by multi-temporal satellite images . After performing the geometric rectification, registration and overlay processing, the average ice velocities of the Polar Record Glacier are measured and calculated and their changing characteristics are analyzes and evaluates.
