| 摘 要： | 针对温冰川冰内及冰下水系(又称冰川排水系统)演化及其水力过程,回顾了我国20世纪90年代在典型温冰川海螺沟冰川开展钻孔试验及关于冰下河堵溃问题的水文学分析,主要从水文学角度,探讨了消融期温冰川冰内及冰下水系的演化过程及其在径流过程曲线上的反映.利用径流-气温交叉相关分析方法,计算了海螺沟冰川2003—2005年逐日Q-T时滞,其季节变化在一定程度上指示了冰内及冰下水系季节演化过程及其水力状况,并针对典型时段,重点探讨了二者之间的相关性.

| Abstract: | Englacial and subglacial drainage system of a temperate glacier has a strong influence on glacier dynamics,glacier-induced floods,glacier weathering processes and runoff from glacierized drainage basins. Proglacial discharge is partly controlled by geometry of the glacial drainage network and by melt water production process. The glacial drainage system of some alpine glaciers has been characterized using a model based on the proglacial discharge analysis. In this paper,cross correlation analysis is applied... |
