Because of the influence of climate change and human activities,runoff change has occurred.This paper analyzes the natural runoff series of the upper and middle reaches of the Yellow 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 variations in drainage basin underlying surface and local climate factor brought by human activity affected natural annual runoff. The results are important to know runoff changes and to exploit water resources of the upper and middle reaches of the Yellow River. |
