摘要
以河北省西大洋水库的降雨径流系列为基础,通过降雨径流相关图的绘制对水文序列资料进行可靠性分析,利用降雨径流双累积曲线和年径流系数的变化过程线确定水文分界点,对西大洋水库的1980~2008年入库径流水文系列一致性进行研究。结果表明,西大洋水库1980~2008年的入库径流资料不具有可靠性和一致性,1996年前后降雨径流机制发生了变化,并对其天然径流资料进行了修正。
Base on rainfall-runoff series hydrologic data of Xingdayang Reservoir in Hebei Province. The reliability was analysed through rainfall- runoff correlogram. Hydrological demarcation point was determined through the double mass curve of rainfall- runoff relation and the change process of annual runoff coefficient. The paper selected the Xidayang Reservoir incoming runoff hydrological series consistency from 1980 to 2008 to research. The results show that Xidayang Reservoir incoming runoff hydrological series are unreliable and inconsistent. Rainfall runoff mechanism has changed in 1996. And then the paper modified natural runoff data.
