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融过程的观测,从冰川消融同气温的关系入手,分析了海洋型冰川的消融过程和特征,并探讨了影响冰川消融的其它因素.
The process of glacier ablation is closely related to hydrothermal conditions, meteorological factors, local ice and surrounding terrain and the surface conditions of the glacier.Using the results of GPS measurements in the ice tongue section of Hailuogou, the recent glacier changes in ice tongue and tongue section include the change of scale and thickness The results show that the glacier thickness has been reduced by about 26% since 1989, and the glacier area has decreased by 4.05% since the 1960s. From the observation of detailed ablation process of tongue segment, this paper analyzes the relationship between glacial ablation and temperature, analyzes the ablation process and characteristics of marine glacier, and discusses other factors that affect glacial ablation.
