摘　　要：利用断面试验资料推求河道糙率的主要目的并不在于寻求涧峪上游河道糙率的真实绝对值,而是通过试验资料的分析计算了解它的变化特征,为涧峪上游河道在实际的水位观测与资料分析中如何利用实测数据推求河道糙率打下基础,这也为估算较大的入库流量提供了一个新的途径。This article uses the cross section experiment material inquire river course roughness coefficient the main purpose and no longer in seeks the Jianyu Valley upper river roughness coefficient the real absolute value, but through the experimental material＇s analysis computation, mainly lies in understood that its change characteristic, how does use the measured data inquire river course roughness coefficient for the gorge valley upper river in the actual water level observation and the material analysis to build the foundation, this has also provided a new way for the estimate big warehousing current capacity.

关 键 词：河床糙率 反演 多项式回归
