| 摘 要： | 根据有关水文气象台站的观测数据，利用定级分类，滑动平均和波谱分析等方法，对黑河出山径流（莺落峡水文站）年际变化特征进行了分析研究，发现黑河出出径流的多年变化具有持续性，周期性和丰枯水变化较平稳，波幅不大等特性，并在此基础上对其未来变化的趋势进行了预测和分析。

| Abstract: | 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. |
