摘　　要：梧州水文站是珠江流域西江干流的重要控制站,水位流量关系复杂。为了解决流量实时在线监测和水文资料整编定线难题,满足不断拓宽水文服务领域的需求,采用落差指数法对梧州水文站水位流量关系进行单值化分析,对西江干流水情预警、水文分析评价具有十分重要的意义。结果表明:基于分年Z~q关系曲线和综合Z~q关系曲线采用落差指数法对梧州水文站水位流量关系进行单值化处理可满足水文资料整编规范要求;基于综合Z~q关系曲线的落差指数法易操作,使流量监测工作效率得到提高。As the key control station on the main stream of Xijiang River in the Pearl River Basin, Wuzhou Hydrological Station is characterized by complex stage-discharge relation. In order to solve the alignment problem of realtime on-line flow monitoring and hydrological data compilation, meet the demands of expanding the scope of hydrological services, single-valued analysis of stage-discharge relation was conducted by drop index method for Wuzhou Hydrological Station which is very important for the regime alarm, hydrological analysis and evaluation of the main stream of Xijiang River. The results of analysis demonstrate that for Wuzhou Hydrological Station, single-valued processing of stage-discharge relation by drop index method and based on annual and comprehensive Z~q relation curves is able to meet the requirements of specification for hydrological data compilation;drop index method based on comprehensive Z~q relation curve permits easy operation and is able to improve the discharge monitoring work efficiency.
