| 摘 要： | 本文采用分形理论计算了四川旱涝灾害时间分布序列的分数维，其结果初步证实了四川旱涝灾害时间分布在一定区间范围内的无标度性。无标度区的跨度及相应的分形维数可作为四川旱涝灾害自组织程度的量度。

| Abstract: | Based on the fractal theory,this paper calculates the fractal dimension of time series of dryness/wetness disasters in Sichuan.The results prove the scaling characterization of time series of dryness/wetness disasters of Sichuan in a certain time range.The length of scaling range and corresponding fractal dimension are taken as the measure of self organization level of dryness/wetness disasters of Sichuan. |
