摘要
采用1952—2013年资料分析了黄河内蒙古河段凌汛期槽蓄水增量时空变化特点及主要影响因素,在此基础上建立了槽蓄水增量预估公式。黄河内蒙古河段槽蓄水增量呈逐年增加趋势,1990年起明显增加,加重了内蒙古河段防凌负担。分析表明,河道过流能力减小是造成槽蓄水增量增加的最主要因素,同时凌汛期上游来水量增加、凌汛期气温变化剧烈也是造成槽蓄水增量增加的重要因素。
The spatial and temporal characteristics of water storage in ice-flood season of the Inner Mongolia reach of the Yellow River were analyzed,as well as the main influencing factors with the data from 1952 to 2013 and the water storage estimation formula was built. It shows an increasing trend of the water storage in ice-flood season of the Inner Mongolia reach of the Yellow River, with a significant increase since 1990, which adds to the burden of ice-flood prevention. It shows that the river flow capacity decrease is the main cause of water storage in-creasing in the Inner Mongolia reach, while the reservoir drainage increasing and dramatic temperature changes in the ice-flood season both contribute to the increasing of water storage.
