| 摘 要： | 洪水点据序列具有随机性、非线性、确定性和相似性,这些特性与分形理论研究的对象一致,因此可应用分形理论进行洪水分期的研究。以湘江流域为例,通过分析湘潭水文站洪水散点序列,计算容量维数,确定洪水分期数目,最终划定了湘江流域的洪水分期,并与传统洪水分期方法进行了比较。结果表明,用分形分析法得到的湘江汛期洪水分期和传统方法结果基本一致,但分形理论计算较为客观,说明分形理论在洪水分期中是可行的,值得深入探讨和应用。

| Abstract: | Flood data sequences are characterized by randomness,nonlinear,uncertainty,and similarity.The characteristics are consistent with the study object of the fractal theory,so flood can be staged using fractal theory.Taking Xiangjiang River basin as an example,flood season of Xiangjiang River basin is staged through analyzing flood data sequences of Xiangtan staff gauge station,computing capacity dimension,and determining the number of flood season staged.The new method is then compared with the traditional method of flood season staged.It is revealed that the stages of Xiangjiang river basin determined by using fractal theory are consistent with those from traditional method,but the method using fractal theory is much more objective.It is feasible in flood season staged and needs to be discussed and applied further. |
