摘要
通过对崇左水文站2007年3月2日至7月4日共计35份实测流量进行分析,提出采用上下游水位差建立受电站蓄水影响后水位-流量关系分析思路,并推求出相关曲线及回归方程式,经检验:成果不存在明显的系统误差,所推流量能满足实际预报要求,对解决简化中小河流站流量监测有一定借鉴作用。
Analysis was made on the 35 pieces of flow records of Chongzuo Hydrological Station dating from March 2 to July 4 of 2007, based on which the author put forward the idea of utilizing water head to find out the level-flow relation influenced by impoundment of power station, calculate relevant curves and regression equation. The results of examination demonstrate this method renders no significant systematic error, and the calculated flow meets prediction requirements, which may be reference for simplification of flow supervision of middle and meets rivers.
