摘要

This paper deals with time series of the Yellow River daily flows at Tongguan hydrological station,from the year 2000 to 2005.Power spectrum analysis and statistical moment scaling function on a range of scales revealed scaling qualities of the data.The partition function,which displayed a convex curvature,and the generalized dimension function showed that multifractality is presented.The singularity spectrum,which is single-humped,has shown strong multifractality degree.
