| Abstract: | Multi-analytic functions of wavelet analysis in time domain and frequency domain were used to analyze different hydrologic cycles of Songhua River Valley in accordance with the annual runoff data of Harbin Station for 83 years.The exact time of runoff abnormality and the alternating changes from high runoff to low runoff were obtained by means of the coefficient diagram of Marr wavelet transform,which provide some bases for the mid and long term hydrological forecasts. |

| Keywords: | Wavelet transform Multi-time scale Annual runoff |
