摘　　要：水位流线关系曲线为水情预警预报分析研判提供支撑,但是由于条件限制,对于无人值守的中小河流站点,往往难以施测到高水流量,部分站点因受高水漫过施测场地等影响,现有条件无法施测高水流量。因此,如何合理地对水流线进行高水延伸,是一个需要解决的问题。以容县中小河流黎村河为例,在进行洪水调查及已有的实测资料基础上,采用比降面积法、水文比拟法来分别推求洪峰流量,探讨在无测验条件的中小河流站点进行流量高水延长的合理性。Water level-flow relationship curve is the support of water regime forecast and analysis.However,it is difficult to measure high water flow at those hydrological stations on small and medium rivers without staff on duty due to limited conditions such as the measuring yards of some stations being even submerged under high water level.Rational upward extension of flow curve is required therefore.Taking the Licun Hydrological Station on Licun river in Rong County as example,on the basis of flood investigation results and available measurement records,peak flood flow was calculated by slope-area method and hydrologic analogy method respectively.The rationality of upward extension of flow curve was discussed for station on small or medium river without measuring condition.
