Multifractal analysis of the Yellow River flows

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.
