摘　　要：河段糙率是计算水库、水电站回水和确定淹没搬迁线的重要参数。本文以京南水库为例 ,通过分析河段糙率特性 ,建立各河段的水位～糙率关系应用于回水计算 。The river reach roughness is a important parameter for calculating reservoir and hydropower station backwater and determining submerge and move line. Using the Jingnan hydropower station for example, by analyzing the river reach roughness features, the water level roughness relation of all river reach were built for backwater calculation and it is able to be taken for reference of the similar hydraulic calculation and river water surface curve analysis.
