摘　　要：冰川运动速度通过控制冰量输送变化影响冰川进退,认识冰川运动及影响机制有助于理解冰川变化差异性机理.利用ITS LIVE冰川运动速度数据分析了亚洲高山区冰川运动时空特征,并基于地理探测器和相关分析探讨了亚洲高山区冰川运动及其变化的影响因素.青藏高原东南部和兴都库什山冰川运动特征值较大,西昆仑山、青藏高原中部、青藏高原东部、东天山等区域冰川运动特征值较小.2000—2016年,亚洲高山区大多数冰川呈现减速的状态,念青唐古拉、横断山等地区冰川减速幅度最大,而西昆仑等地区冰川呈现增速状态.冰川运动主要受规模因素控制,兼受地形和气候等因素的影响,冰川运动变化主要受冰川物质平衡或者厚度变化的影响.Under climate change,glacier movement controls mass transport changes,which further leads to the response of changes in glacier length,area and thickness.However,there are differences on response time and degree for glaciers in different scales and types.For further understanding the mechanism of heterogeneous glacier changes,the spatial and temporal characteristics of glacier movement in the High Mountain Asia were analyzed by using ITS_LIVE glacier velocity data.And the influencing factors of glacier movement,glacier velocity change were analysed by Geodetector and correlation analysis.The results are as follows:The characteristic values of glacier movement are larger in the southeastern Tibetan Plateau and the Hindu Kush,but smaller in the West Kunlun,the eastern Tianshan and the eastern Tibetan Plateau.Most glaciers in the High Mountain Asia were slowing down during 2000-2016.Glaciers in Hengduan and Nianqentanglha Mountains decelerate most dramatically.In contrast,West Kunlun experience slightly accelerated glacier movement.Glacier movement is mainly controlled by glacier length and area(thickness),as well as terrain and climate factors.The change of glacier mass balance or thickness is the most important reason for glacier movement change.
