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. Aiming at the evolution and the hydraulic process of the inner and outer glaciers (also known as the glacial drainage system) in Wenchuanchuan, this paper reviews the drilling tests conducted in the typical glacier of Hailuogou Glacier in Wenchuan in the 1990s and the water The literature analysis mainly discusses the evolution process of the glacier ice and the ice water system during the ablation period and its reflection on the runoff process curve from the perspective of hydrology.Using the cross-correlation analysis of runoff and air temperature, The seasonal QT delay in 2005 indicates that the seasonal variation of the seasonal variation of the water system in ice and ice shows the seasonal evolution process and its hydraulic status. In the typical period, the correlation between them is discussed.
