摘要
根据在水文现象中广泛存在的自相似性，将标度不变性引入洪量历时关系，对大流域洪量随历时变化的性质进行了研究． 用全国不同流域、不同地理气候条件地区的 17 个水文站的洪水资料，对洪量随历时的变化性质进行了研究． 结果表明：在一定的历时范围内，大流域洪量随历时变化具有单标度性质． 由洪量随历时变化的标度性质，建立了洪水强度历时公式．
The scaling hypotheses were applied to study the problems of variation of flood volume in large basin with duration in this paper． By using the flood data from 17 hydrologic stations in China，the variation of the annual maximum flood volume with duration was studied．The results demonstrate that the variation of annual maximum flood volume with duration in large basin has simple scaling propery in some range of time． Basing on the scaling property,the flood intensity-duration formula was given．
