| 摘 要： | 乌鲁木齐河山区冰和雪资源，对径流补给，其量不很大，但对河水稳定起着很大作用和影响，冰川近几十年来一直退缩，冰川厚度冰薄，但冰川和融雪对乌鲁木齐河径流一直起着调剂和“保证”作用，山区冰川水（补给11．3％），融雪水（36．1％），降水是其必要的补给。从360年重建年径流可知，平水年频率57．7％，偏丰和特丰年较少（17．4％，1．7％），偏枯年23．2％特枯年为0。

| Abstract: | Ice and snow in source area of Urumqi River supply few water for runoff,but it take much effect to flow discharge of the river.In recent dozens years,glacier flinches continuously,it's thickeness is decreasing.The glacier and snow take the effect of adjusting and retaining to runoff in Urumqi River.The glacier and snow water in source area and precipitation are essential supplier for the runoff.From reconstructing the annual anount of the runoff for 360 years,the frequency of normal flow year is 57.7%,partial and special high flow year are fewer,partial low flow year is 23.2 percent and special low flow year is zero. |
