| Popis: |
The periodicity and the trend which are the important properties of water resources become more and more variable and complex because of the influence of topography, vegetation and the human activities. Wavelet Analysis which has Multi-resolution Analysis function can provide more detail information of the nonlinear and complex system. The periodicity and the trend of precipitation in different plain regions of Handan are illuminated with Morlet Wavelet Transform in Multi-time scales in this study. It is illustrated that the same periods (5years and 9years) exist in the precipitation in different plain regions of Handan and there are the similar variety and the similar trend in the scale of 5years or 9years in different areas. This study would provide technical support for the integrated management and utilization of water resources of the local region. |
