摘　　要：实现流量在线监测是提高水文测报现代化水平的重要前提,目前水文自动测流技术研究中多普勒频差原理广泛应用,自动测流设备适用程度较高,能够实现自动化监测,但不同设备又都有其局限性与应用范围,具体自动测流方案的选择要充分考虑测流断面的特性,同时必须根据历史数据与资料进行充分论证和精准分析。结合石梁河水文站测流断面,从技术方面对垂直式声学多普勒流速剖面仪和侧扫雷达设备进行充分论证和精准分析。The realization of online flow monitoring is an important prerequisite for improving the modernization level of hydrologic measurement and prediction.At present,the research on hydrological automatic flow measurement technology mainly uses the principle of Doppler frequency difference.Automatic flow measurement equipment has a high degree of applicability and can achieve automatic monitoring.However,different equipment has its limitations and application scope.The specific selection of automatic flow measurement scheme should fully consider the characteristics of the flow measurement section,and must be fully demonstrated and accurately analyzed based on historical data and information.Combined with the flow measurement section of Shiliang River hydrological station,a comprehensive demonstration and accurately analysis of the vertical acoustic Doppler velocity profiler and side scanning radar equipment are conducted from a technical perspective.
