摘要： 运用小波分析等方法对黄河上中游天然径流序列进行了分析,揭示了河川径流多时间尺度变化规律,并对径流在不同时间尺度上变化的影响因素进行了探讨。研究结果对于认识黄河径流的变化规律、开发利用管理黄河水资源有着重要的意义。

Abstract: Because of the influence of climate change and human activities,runoff change has oc-curred.This paper analyzes the natural runoff series of the upper and middle reaches of the Yel-low River with the theory of wavelet transformation,reveals multi-time scale changes rule of runoff,and discusses the influencing factors of runoff multi-time scale changes.The results showed that climatic conditions such as precipitation mainly controlled river runoff variations.But varia-tions in drainage basin underlying surface and local climate factor brought by human activity af-fected natural annual runoff.The results are important to know runoff changes and to exploit wa-ter resources of the upper and middle reaches of the Yellow River.

Key words: Yellow River, runoff changes, multi-time scale, wavelet analysis
