摘　　要：八宝河为典型的山溪性河流,多点法测速难度较大。通过对八宝河水量控制站祁连水文站(以下简称祁连站)流量测验断面测速垂线相对水深位置0.0、0.6的测点流速进行分析,计算出水面流速系数试验值范围,推导出一点法半经验公式试验系数,用实测试验数据定性水面流速公式,以应用于水文测站转子式流速仪、雷达波流速仪流量测验中。Babao river is a typical mountain stream river,and it is difficult to measure velocity using the multi-point method.By analyzing the velocity of the measuring points at the relative water depth positions of 0.0 and 0.6 of the velocity vertical line of the flow test section of the Qilian hydrological station(hereinafter referred to as the Qilian Station)of the Babao river water control station,the test value range of the water surface velocity coefficient was calculated,and the test coefficient of the one-point method semi-empirical formula was derived.The water surface velocity formula was qualitatively determined using the actual test data,so as to be applied to the flow test of the rotor current meter and radar wave current meter at the hydrological station.
