分析珠穆朗玛峰峰绒布冰川强消融期6月的日径流资料可知,由于绒布冰川末端冰湖较为发育、冰川面积较大,冰川末端水文站显示白天流量小于晚上流量,冰川储水性较强.最大流量出现时间滞后於最高气温(消融最强)时间9~14h.随着消融强度增大,冰川排水系统发育越来越完善,滞后时间缩短.据2005年定日县气象站无降水日日平均气温资料和同期珠穆朗玛峰绒布河日均径流量,获得气温驱动下绒布河日均径流量表达式;利用1959年珠峰科考时一个水文年中无降水日绒布河日均流量资料和同期定日县气象站日均气温检验该表达式表明,该表达式在利用定日县气象站无降水日日均气温模拟绒布河径流量时表现较好.绒布河的径流可分割成两部分:冰川融水补给和降水补给.根据1959年降水驱动产生的流量,得出降水对河流补给贡献率为19.2%,冰川融水补给率为80.8%.
Analysis of the daily runoff data from Everest peak glacier glacier in June shows that due to the relatively developed glacier at the end of the flanagan glacier, glacier area is larger, and the hydrological station at the end of the glacier shows that the daytime flow rate is less than the nightly flow rate, and the glacier has higher water storage capacity. Appear time lag at the highest temperature (ablation strongest) time 9 ~ 14h.With the ablation intensity increases, the glacier drainage system development is more and more perfect, the lag time shortened.According to Dingli County weather station in 2005 without precipitation daily average temperature Data and daily average velocities of velveteen in Mount Everest during the same period were obtained. The mean daily average runoff of velveteen was obtained from the temperature-driven velveteen. The average daily temperature of county meteorological station test The expression shows that the expression in the use of Dingri County weather station day without precipitation daily temperature simulation velvet river flow better performance .Floria River runoff can be divided into two parts: Replenishment and Precipitation Supply According to the flow produced by precipitation-driven in 1959, it is concluded that the contribution rate of precipitation to river recharge is 19.2% and that of glacier melt supply is 80.8%.
