| 摘 要： | R/S(重标极差)分析法是一种描述分形结构的有效方法.针对径流序列所具有的复杂的随机性和波动性,应用R/S分析法,通过对时变指数Hurst的计算及其检验,以新的视角对河川径流时间序列的分布特征、统计循环长度等复杂特性进行了有益探索.实际径流时间序列的计算结果表明:黄河上游径流序列服从分形分布,具有较强的状态持续性,而且拥有一定的非周期循环,这为水资源的合理开发利用提供了一种新思路和新方法.

| Abstract: | Rescaled range(R/S) analysis is a useful method in representing fractal structures.To study the complex stochastic and undulatory property of the runoff time series,an R/S method is used.Through the time-varying Hurst index,complicated properties of runoff time series are investigated from a new angle.The results indicate that runoff time series in the upstream of the Yellow River follow a fractal distribution,showing a strong persistence and a certain non-periodic cycle.This provides a new idea and method for the rational exploitation and utilization of the water resources. |
