摘要
针对分形分析方法在水库汛期分期应用过程中存在的参数选取问题,对可能影响分期结果的切割水平以及时间尺度范围进行了参数优选,并以崖羊山水库的汛期分期为例,利用分形分析方法获得了该水库的汛期分期结果,经过对比分析数理统计法、模糊集合论方法的分期结果,进而验证了分形分析方法具有更高的准确性。
Aiming at the determination of parameters in the application of fractal analysis method in division of flood season, parameter optimization was done on the potential factors for influencing the results of division including splitting level and the range of time scale. Taking Yayangshan Reservoir as an example, the result of division of flood season is ob tained by fractal analysis method. Furthermore, through the comparison and analysis of the results of empirical statistics and fuzzy set theory method, it verifies that fractal analvsis method is more accurate.
