Abstract
采用归一化互相关算法精确配准Landsat 8影像得到了2014年—2016年不同季节冰川的运动速率，并利用其热红外波段对不同时刻的地表温度进行反演；通过强度追踪法处理TerraSAR-X影像得到了2008年4月—10月不同时段的冰川运动速率。两种数据得到的结果表明：冰川末端流速较小，中部流速增大，流速从轴部向两侧递减；冬季流速明显小于夏季，变化趋势与温度变化具有一致性。冰川西侧分支的移动速率相对较大，从Landsat 8和TerraSAR-X提取的最大速率分别为2.56 m·d-1和2.74 m·d-1。最后对稳定区域的冰川流速进行统计，结果显示Landsat 8提取的冰川流速精度控制在1—9 cm·d-1，基于TerraSAR-X的强度追踪法提取移动速率的精度控制在2 cm·d-1，验证了两种数据监测冰川移动的可靠性。
