摘要

摘要: 用分形理论对洪峰散点序列进行了分析,发现洪峰散点序列在一定尺度范围内表现出了自相似性,初步证明洪峰散点序列是一种分形。提出了用分形理论划分洪水分期的方法,并以雅垄江小得石站洪水分期研究为例。结果显示,用分形法划分的洪水分期和传统的经验方法划分的洪水分期基本一致,但和传统方法相比,新方法的优点较为客观。

Abstract: In this paper,The characteristics of flood events series have been analyzed by using fractal theory,it is shown that the flood events have the character of self-similarity,and is a fractal.Further,a case study on the seasonal flood periods classification at the station of Xiao Deshi in Ya Long river is given,the results show that the periods determined by using fractal theory are consistent with that from traditional method.In comparison with traditional method,the new method is much more objective.
