摘要
乌鲁木齐河源冰川径流采用实测的1号冰川物质平衡、降水等为基本资料进行估算:冰川强烈消融期在7月中旬-8月中旬,冰川多年平均径流深度为442mm。相当于冰川每年减薄135mm。用“替代冰川”估算出山口以上冰川总径流量为1.87×10 ̄7m ̄3,占英雄桥总径流的8%。
The glacial runoff in the source of Urumqi river is estimated based on observation dataof specific glacial mass balance; glacial runoff, and precipitation. The main results of this ana-lysis are: 1) The key ablation period of glaciers in this region occurred from mid July to midAugust. Temperature in the period appears to be a major control of glacial runoff.2) Meanannual melt runoff depth of Glacier No.1 is 442mm/a during the 34 year period between1958-1992. It is equivalent to 135mm/a of the glacier thinning. 3) Glacial melt wateroutflow near the outlet of mountain river was calculated by using 'glacial substitution meth-od'. New estimate, 1.87×10~7m^3 accounts for 8% of the outflow totals at Hero Bridgestreamflow station.
