摘　　要：通过对黄洞水文站固定式雷达测流系统与走航式ADCP等流量测验结果进行对比,分析率定黄洞水文站固定式雷达测流系统水面流速系数。比测结果表明,固定式雷达测流系统在高水和中水水位对黄洞水文站流量实现在线监测是可行的,对低水部分不适用,尤其是在流速小于0.5m/s时(相当于雷达监测系统启动流速),测流精度明显下降。The flow measuring results out of fixed radar system and navigable ADCP were compared, based on which the water surface flow velocity coefficient was analyzed and calibrated for the fixed radar system of Huangdong Hydrological Station. The results of comparative measurement demonstrate that on-line flow monitoring with fixed radar system is feasible for Huangdong Hydrological Station at high or middle water level, but it is not applicable at low level, especially the flow measurement accuracy decreases obviously when the flow velocity is less than 0.5m/s,equivalent to the starting flow rate of radar monitoring system.
