摘　　要：淮河中游区支流、行蓄洪区多,水位流量关系影响因素多,各流量控制站水位流量关系散乱。为了实现水文现代化的目标,需要补齐水文单值化分析短板。本文依据安徽省淮河干流站2020年大洪水实测资料,采用落差指数法进行单值化分析。结果表明:中高水期各站水位与流量校正因数为单一线关系,定线指标满足整编规范有关要求,可用于流量报汛和资料整编,分析成果为淮河干流站实现流量“软在线”提供依据。In the middle reaches of Huaihe river,there are many tributaries and flood storage areas,and there are many factors affecting the relationship of water level and discharge.The relationship of water level and discharge at each flow control station is scattered.In order to realize the goal of hydrologic modernization,it is necessary to complete the short board of hydrologic univalued analysis.Based on the measured data of the major flood in 2020 at the main stream station of the Huaihe river in Anhui province,this paper used the drop index method to make a single valued analysis.The results showed that there is a single line relationship between the correction factor of water level and flow of each station in the middle and high water period.The alignment index meets the relevant requirements of the BGF standard,which can be used for the flood reporting and data compilation of the flow.The analysis results provide a basis for the realization of"soft online"flow of the Huaihe river main stream station.
