| 摘 要： | 冰川消融过程与水热条件、气象要素、冰面局地和周边地形以及冰川表面状况等密切相关.利用海螺沟冰舌段GPS测量的结果,对冰舌段的冰川近期变化包括规模变化和厚度减薄进行了新的评估.结果表明:自1989年以来冰舌段冰川厚度减薄约26%,远显著于20世纪60年代以来冰川面积的减少比例4.05%.基于对海螺沟冰川消融区冰舌段详细消...

| Abstract: | Glacier ablation process is controlled tightly by energy.Ablation intensity is influenced by spatial and temporal changes of air temperature,ice surface conditions and surrounding terrain,and so on.In this study,a detailed ablation observation was carried out on the ice surface of lower ablation area of the Hailuogou Glacier during 2008 ablation seasons,from April to October.Relationship between ablation and cumulative positive air temperature was analyzed.It is found that strong ablation occurred from July... |
