根据冰川编目、Landsat MSS/TM/ETM+影像和相关的历史考察制图,利用GIS进行了不同时期的冰川分布图的制作,对比分析了不同时期冰川范围.重点监测了喀喇昆仑山北坡克勒青河的5Y654D48、5Y654D97的不同时段内的冰川运动状况.结果发现:5Y654D48冰川和5Y654D97冰川分别在1990—2000年与1977—1990年间运动速度达272 m.a-1,213.1 m.a-1,比其它时段运动速度大7~20倍,具备跃动冰川的运动特征.分析认为,5Y654D48冰川在1990—2000年、5Y654D97在1977—1990年间曾分别发生过冰川跃动.
Based on glacier cataloging, Landsat MSS / TM / ETM + images and historical mapping, the author made use of GIS to make glacier distribution map in different periods and compared the glacier range in different periods.It focused on monitoring the northern slope of Karakoram The results show that the movement velocity of 5Y654D48 glacier and 5Y654D97 glacier reached 272 ma-1,213.1 ma-1 between 1990-2000 and 1977-1990, respectively, which was higher than those of other periods 7 to 20 times, with the characteristics of the glacier movement.Analysis that 5Y654D48 glacier in 1990-2000, 5Y654D97 in 1977-1990 glaciers have occurred during the jump.
