Abstract	Based on the distribution characteristic of frequencies of hydrological time serial and wavelet analysis, the time serial made of different frequencies is decomposed into the low and high frequencies by scale. The trend composition of time sequence is resorted according to the reconstruction theory of wavelet coefficient, so that the trend of hydrological time sequence is judged. This paper studied the measured annual runoff sequence of four hydrological stations in the Yellow River. The result shows that it is feasible to apply multi-resolution analysis in analyzing hydrology time sequence tread.
