| 摘 要： | 目的:探索河川径流的周期波动性,揭示河川的径流的丰枯交替以及干枯或洪峰的规律,进而计算出全局性的主要周期,从而达到反应河川径流整体特性的目的.方法:运用极大熵谱法,经基于Burg算法的AIC准则来选择模型参数,分析河川径流的主要周期.结果:将极大熵谱分析方法应用于后河径流演化规律分析中,结果显示:后河具有5年的显著周期.结论:极大熵谱分析法分辨率高,也可为未来总结、预测年径流变化的规律奠定基础.

| Abstract: | Objective： To explore the period of runoff and reflect the law of water shortage and flood peak, and to calculate the period of runoff in order to observe the runoff＇s integrality. Method： By using the maximum entropy method to analyze the period chosen parameter by the criterion of AIC. Result： The period of Houhe is 5 years. Conclusion： The method has a higher resolution ratio and it can provide a better way to tbrc~ast the law of runoff in the t＇hture. |
