以冰川形态因子变量(面积、长度和厚度),气候条件因子变量(年气温、降水),以及年物质平衡量等作为影响因素,采用通径分析方法研究了祁连山七一冰川1958-2007年间年际运动速度的影响因子强度.结果表明:冰川形态对运动速度的影响强度最大,物质平衡的影响次之,而气候条件的影响最弱.在这些影响因素中冰川面积和厚度对运动速度的影响较为显著,其直接和间接的通径系数分别是6.56、4.71和19.29、13.57.为认识冰川运动速度的内外影响因素提供了科学参考依据.
Taking the variables of glacier morphology (area, length and thickness), climate condition variables (annual temperature, precipitation) and annual mass balance as the influential factors, the path analysis method was used to study the Qilian Mountains Qiyi Glacier between 1958-2007 The results show that glacier morphology has the strongest influence on the moving velocity, the next is the material balance, and the weakest is the climatic conditions.In the influence of glacier area and thickness on the moving velocity The direct and indirect path coefficients are 6.56, 4.71 and 19.29, 13.57, respectively, which provide a scientific reference for understanding the influencing factors of glacier speed.
