基于大伙房水库汛期分期变化的供水量长序列调节

Water supply long sequence adjustment Based Dahuofang reservoir flood stage variation

本文以大伙房水库1959―2014年的出入库水量资料为基础,采用年径流集中度对大伙房水库汛期分期变化进行分析,同时对大伙房水库汛期分期变化的供水量进行长序列调节。结果表明,大伙房水库主汛期有延后趋势,且延后主汛期后设计工业及城市、农业、生态供水量减少,弃水量增加。

based on Dahuofang Reservoir out of storage of eentration analyzed Dahuofang flood stage changes, meanw water data In 1959-2014,with annual runoff conhile also regulated long sequences of water supply during Dahuofang flood stage changes.The results showed that the main flood season of Dahuofang trend has delayed and the main flood season design of industrial and urban, agricultural, ecological water supply reduction, increased water abandoned.
