| 摘 要： | 综合研究了黑河上游祁连山冰沟流域2008年积雪期水文情势,以积雪-冻土-径流为框架详细分析了该地区积雪水文特征.采用物质平衡计算了冰沟流域雪蒸发和融水值,并分析了冻土水热变化过程和融雪径流变化特征.积雪期降水总量达到204.6 mm,雪而蒸发为140.8 mm,雪面蒸发在积雪期水文循环中占有重要的位置.3月12日融雪开始,引起3次人规模的融雪峰值;整个融雪季,冰沟流域融雪径流总嚣为3.98×106m3.冻土解冻始于4月12日左右,随着气温升高,土壤含水量变化明显.地形和风速相巨作用,造成积雪的大规模重新分布.

| Abstract: | The snow hydrological process in Binggou watershed in the upper reaches of Heihe River is described synthetically in this article,and the special snow characteristics in the watershed are analyzed in detail in a framework of snow-frozen soil-runoff.Snow sublimation and melt are calculated by the energy balance methods.The changes of water content and thermal properties of the frozen soil and the snowmelt runoff in Binggou watershed are analyzed too.The importance of blowing snow is illustrated especially.Th... |
