The mountain glacier is an indicator of climate change and represents important archives of past climatic information [1].The effects of climate warming are for instance evident in the continuous retreat of glaciers in many mountainous regions,and even the most optimistic scenarios for future temperature change involve pronounced glacier retreat over many decades to come [2].Monitoring glacier flow rates is important in studies of glaciers responding to climate change; in particular,it helps in understanding their dynamic responses to climate change and their potential impact on water resources,sea level,and glacier-related hazards.In this study,we have used the combined methods (InSAR and Offset-tacking) to demonstrate that accurate and detailed map of the ice-velocity field can be routinely obtained on mountain glaciers by L-band SAR data.We derived twelve glaciers’ motion in Muztag Ata and gave a detailed analysis of the different types,different sizes and different orientations glaciers’ motion features and changes in Muztag Ata according to the motion results of the 2008,2009 and 2010.
