| 摘 要： | 以长江流域3个水文站的洪水资料为例，应用标度理论，对洪量随历时变化的标度特性进行了研究。研究结果表明：在一定的历时范围内，年最大洪量随历时变化具有单标度性质。由洪量随历时变化的单标度性质，建立了洪水强度历时公式，可直接求出不同历时的年最大洪量值，与常规方法计算结果相比，二者十分接近。

| Abstract: | Using the flood data from three hydrologic stations in the Yangtze river, the temporal scaling properties of flood volume is studied with scaling theory. The results demonstrate that the variation of annual maximum flood volume with duration has a simple scaling property in a certain period of time. Based on the scaling property, the formula describing the relationship between flood intensity and duration is established. The annual maximum flood volumes are computed by use of this formula. The computed result approximates to the one obtained by the conventional method. |
