在补给区，根据14个测站资料和18号氧月过程线资料，将黑河径流分为冰雪融水和降水两部分。二组分混合模型的结果表明，平均19.8%的径流来自冰雪融水。在距离冰川较近且有冰雪融水源头的三个站，冰雪融水径流量大于河流径流量的28%。此外，由于大部分冰雪融水渗入地下水，然后在山区出口处排入河流，因此在海拔高于3，600 m的站点，冰雪融水在径流中的比例低于平均水平。从月过程线来看，冰雪融水在径流中所占比例最小的是7月（6.46%），最大的是11月（26.1%）。在中部流域，由于农业漫灌的影响，地下水在径流中所占的比例由张掖市附近的23.57%上升到高台市附近的60.28%，然后又急剧下降到正义峡站附近的13.61%。
In recharge areas, the Heihe River flow was separated into components of ice-snowmelt and precipitation according to 14 gauging stations and to monthly hydrograph using oxygen-18. As shown by the result of the two-component mixing model, on average, 19.8% of the runoff comes from ice-snowmelt. At three stations which are closer to glaciers and with headstream of ice-snow melted water, the ice-snowmelt runoff is larger than 28% of stream water. In addition, because most of the ice-snowmelt infiltrates the groundwater, which later discharges into the river at mountain outlets, the ice-snowmelt percentage in runoff is lower than average at these stations with the elevation higher than 3,600 m. According to monthly hydrograph, the lowest percentage of ice-snowmelt in runoff is in July (6.46%), whereas during November it is the largest (26.1%). In the middle basin, the fraction of groundwater in runoff had a marked increase from 23.57% near Zhangye City to 60.28% near Gaotai City, and then a dramatic drop to 13.61% near Zhengyixia Station because of agricultural flood irrigation in Zhangye Basin.
