| 摘 要： | 流域汇流受到河网形态的影响,考虑到水系的分形自相似特性,利用在文献1]基础上改进的方法构造了理想的自相似网络(SSNs),并推导出相应的宽度函数(WF)表达式.以WF为基础,得到流域地貌瞬时单位线.利用生成的单位线对沿渡河流域11场洪水进行汇流计算,结果表明,所提出的方法应用于流域汇流计算具有较好的精度.

| Abstract: | Considered the fractal self-similar characteristics of river system,ideal self-similar networks is constructed and then the corresponding width function is derived.Based on the width function,the basin geomorphological instantaneous unit hydrograph is derived. The results of the test of 11 floods in Yandu River basin is satisfactory. |

| Keywords: | fractal selfsimilar networks width function basin geomorphological instantaneous unit hydrograph |
