Abstract：In this paper , the multifractal behavior on the daily runoff series of the Yangtze River from 1950 to 1999 is discussed .The partition function χq(ε) , exponent function τq , generalized fractal dimen-sions Dq,singularity αand multifractal spectrum f(α) are calculated.It is found that this series of differ-ent timescales, namely, one year and 50 years, obey multifractal scaling.The results provide theoretical basis for the research of runoff series ’ nonlinear characteristics .
