　　摘 要：針對松柏水文站在發生暴雨洪水時河流陡漲陡落，高洪時漂浮物多，采用流速儀或ADCP測流不安全的問題，應用移動雷達波測流系統進行流量測驗。在分析測流系統組成、工作原理、管理軟件的基礎上，按照不同水位級布置測次，采用同期測流系統施測流量與轉子流速儀人工實測流量進行比測，建立2種流量相關關系，率定測流系統流量系數，并進行誤差分析評判，驗證移動雷達波測流系統測流精度。比測率定結果表明：兩者相關關系良好，移動雷達波測流系統測得的水面流速經率定后，推算的斷面流量精度較高，滿足水文資料整編精度及水資源管理要求，可提高水文資料時效性和準確性，解決山溪性河流流量測驗安全問題。

　　Abstract： In view of the problems of sharp river rise and fall, and many floating objects during high flood in the Songbai hydrological station, it is unsafe to use current meter or ADCP to measure flow. For this reason, the mobile radar flow measurement system is adopted for flow test. On basis of current system components, functions and management software, the measurement times are set according to different water levels, and flow measured by the simultaneous flow measuring system is compared with the manually measured flow measured by rotor current meter. Correlation relationship between the two flows is established, and flow coefficient of the flow measuring system is calibrated. Error analysis and evaluation are carried out to verify the accuracy of the mobile radar wave current measurement system. Calibration results show that the correlation relationship is good, the computative cross-section flow precision is high after measuring and calibrating the water surface velocity, by mobile radar wave flow measurement system. The system can satisfy the requirements of hydrological data compilation accuracy and water resources management, improve the timeliness and accuracy of hydrological data, and can be used to solve the safety problem of flow measurement of mountain stream rivers.
