| 摘 要： | 以某水库为研究实例，分析了暴雨量值、暴雨日数等的时程分布规律，提出了采用分形理论进行汛期分期的定量计算方法，以水库历年汛期日最大流量为研究系列样本，以每半个月为计算步长，以分形维相对差5%为临界值，得到新的汛期分期。计算结果表明本文所提计算方法合理可行，为汛期分期划分提供了一种新的思路。

| Abstract: | In this paper,the volume and days of the rainstorm in some one river basin was analyzed.The fractional dimension theory was used as quantitative analysis method to reveal the law of the flood to accompany with maximum daily flux as sample, half a month as calculation step,and diagonal relative error 5% of the fractional dimension as threshold.The result showed this method was reasonable and feasible in the paper. |
