　　摘 要：無人機測流系統是將雷達波流速儀集成在無人機上的一種非接觸式河道流量測驗方法。針對銅仁水文監測工作在遇超標準大洪水或惡劣環境下水文應急監測手段單一、數據精準度不高的問題，采用無人機測流系統在銅仁市茅溪水文站與水文纜道流速儀法進行 22 次實測數據對比試驗，分析無人機測流系統實測的水面流速及流量測驗誤差。結果表明：無人機測流系統在水面流速超過 0.50 m/s、運行高度在 10～30 m、風力小于 7 級時，測流數據的合格率達到相關要求。無人機測流系統在貴州省銅仁市山區性河流應急監測時適應性良好，可作為銅仁水文應急監測一種安全便捷有效的方法進行推廣。

　　Abstract：Drone flow measurement system is a non-contact river flow measurement method which integrates the radar wave current meter on the drone. In view of the problems that the hydrological emergency monitoring method is rare and the data accuracy is not high in Tongren, this paper applies the drone flow measurement system to conduct 22 comparative tests of measured data at Maoxi Hydrologic Station in Tongren City. The data is compared with data measured by hydrological cableway current meter method, to analyze the measured water surface velocity and flow measurement errors of the drone flow measurement system. The results show that the qualified rate of the drone flow measurement system meets the requirements of relevant phases when the water surface velocity exceeds 0.50 m/s, the operating height is 10～30 m, and the wind power is less than Level 7. The drone flow measurement system has good adaptability in the emergency monitoring of mountainous rivers in Tongren City, and can be promoted as a safe, convenient and effective method for Tongren hydrologic emergency monitoring.
