| 摘 要： | 讨论了年水文时间序列的近似周期分析方法,在极大熵谱分析法的基础上设计了一种时间序列分段搜索法,并用计算机软件仿真实现。对湘江下游五强溪水库年径流时间序列分析的实例表明,五强溪水库具有16.7、5、2.8和2 a的近似周期,证实了该方法的可行性。

| Abstract: | This paper discusses the process of approximate cyclic analysis of yeraly hydrologic series,which is based on the method of maximum entropy spectrum,and proposes a method of time series divided search implemented by computer software.The analysis and calculation of the approximate yearly runoff time series at Wuqiangxi station on lower reaches of Xiang River prove that the approximate periods of the yearly runoff are 16.7,5,2.8,and 2 years at Wuqiangxi station.The conclusion illustrates the feasibility of this method. |
