Abstract

The hydrologic process influenced by the multi-action of climate, geography, vegetation and human activities becomes more and more complex, which is the important characteristic of hydrologic system. The different complexity distributions of precipitation process of Chien River Basin (sub-basin of MinChiang Basin) in two periods(one is from 1952 to 1980 and the other is from 1981 to 2009) are illustrated respectively in this paper in which the fractal based on Continuous Wavelet Transform (CWT) is used. The results are indicated as follows: first, in basin scale the precipitation process in the latter period is more complex than that in the former period; second, the maximum value of the complexity distribution moved from the east to the middle and last, through analyzing the time-information and space-information concealed in this complexity change, the precipitation characteristics in changing environment are illuminated in study Basin. This study would provide reference for the research of disaster pre-warning in the changing environment and for the integrated water resources management in the local basin.
