冰川运动研究中,在注意运动速度时空分布特点的同时,人们更注意研究冰川的应变率分布状况。因为它可以从根本上揭示冰体流动速度的变化特点,表明速度的变化梯度,以及速度变化的动力学原因,而且能把流动速度的分布与冰川表面形态、槽谷形状等影响因素有机地联系起来。同时,通过对应变率的分析,还可以发现它与冰川物质平衡等的关系。对乌鲁木齐河源1号冰川表面应变率的研究,就是在上述思想指导下开展
In the study of glacier movement, attention is paid to the distribution of strain rate in the glacier while paying attention to the temporal and spatial distribution of the moving velocity. Because it can fundamentally reveal the changing characteristics of ice body flow velocity, indicating the gradient of velocity and the dynamic reason of velocity variation, and can also make the distribution of flow velocity organically related to the influencing factors such as glacier surface morphology and trough shape stand up. At the same time, through the analysis of the strain rate, it can also find its relationship with glacial material balance. The research on the surface strain rate of Glacier No. 1 in Urumqi is carried out under the guidance of the above thought
