黑河流域面积10009km2，是西北干旱区的一个较大的内陆河流域。干流发源于祁连山，流经甘肃河西走廊，注入内蒙古高原西部，全长821公里。黑河流域地表径流量几乎全部来自英落峡（山口）以上的山地流域。根据流域内邻近的水文、计量站的降水、温度、流量观测资料和野外调查资料，采用分类、离差累积和谱分析方法，分析讨论了峡谷以上干流地表径流的年变化特征。
The Heihe River basin aboveYingluoxia Gorge,10 009 km2 in area, is a greater inland river watershed in the arid Northwest China. Itsmain stream, with a length of 821 km, originates inthe Qilian Mountains and flows throught the HexiCarridor of Gansu Province and enters the westernpart of the inner Mongolia Plateau. The surfacerunoff volume of the Heihe River basin nearly allcomes from the mountainous watershed above theYingluoxia Gorge (mountain entrance). Annual variation characteristics of the surface runoff of the mainstream of the river above the gorge were analysed anddiscussed by using the methods of classification, departure accumulation and spectral analysis, based onthe observations of precipitation, temperature anddischarge at the adjacent metrologic and hydrometricstations in the studied basin, and on field investigation.
