摘　　要：简述了多重分形理论和多重分形谱的算法;基于多重分形理论,用配分函数法对山东省2008-2009年每月的交通事故时间序列进行了多重分形谱研究,得到该时间序列的多重分形谱.结果表明,该时间序列具有多重分形分布特征,该方法为交通事故研究提供了一种新的理论方法.First of all,the multi-fractal theory and the algorithmic of the multi-fractal spectrum were briefly described.Then,based on the multi-fractal theory,this paper presented a research on the multi-fractal spectrum of traffic accident time series in Shandong province from 2008 to 2009 by the partition function and the monthly multi-fractal spectrum of the time series was obtained.The results show that the time series have the characteristics of the multi-fractal distribution.It provides a new theoretical method for the research of traffic accidents.
