Chinese. 南四湖二级坝水利枢纽改造后，堰闸泄流条件发生变化，根据水文规范，利用声学多普勒流量仪（ADCP）收集资料，对现有泄流量推求曲线进行了分析验证。通过实测资料分析表明，泄流曲线已不适用改造后的工程出流条件，初步分析的部分流态系数曲线符合堰闸规律和二级坝工况实际。提出根据工程改造治理后的现状条件，开展二级坝泄流曲线以及湖区行洪研究的建议，为防汛调度、南水北调洪水资源利用提供准确可靠的技术支撑。

According to hydrological specification, the use of acoustic doppler flow meter （of ADCP） to collect information on existing vent flow. Deriving curve analysis verification. Measured data show that the dis- charge curve is no longer applicable after the transformation of engineering flow conditions. Preliminary analysis of the part of the flow pattern coefficient curve in line with the conditions of weir gate law and the two - dam. It is recommended according to the status of conditions in the governance of the engineered to carry out a two - dam discharge curve and lakes flood research to provide accurate and reliable technical basis for flood control and South flood resource use planning.
