| 摘 要： | 水力几何形态关系是对河道形态与水力学特征之间的关系进行定量描述的一种重要方法,对于河道整治有着重要的意义。本文以无定河及其支流为研究区域,利用该流域1959~1969年期间的实测流量资料,分析了34个河段的断面水力几何形态指数。结果发现,无定河所有河道的水力几何形态指数总体上可以分为三类:b>f &; m>f &; b+ f>m;b&; m关 键 词： | 无定河 水力几何形态 空间差异 河道等级 流域面积 拟合关系 |

| Abstract: | The hydraulic geometry is an effective tool in quantifying the relationship between channel morphology and hydraulic variables.The research on hydraulic geometry plays an important role in understanding the channel change caused by natural environment change and it can provide some insightful advice in river restoration and channel design.The study area is located in the Wuding River Basin.Using the data measured during the period 1959-1969,the hydraulic geometry relationships are analyzed for 34 cross-sect... |
