刘家峡、龙羊峡水库相继蓄水运用后,在缓解宁蒙河段凌汛形势、防凌减灾方面发挥了重要作用,取得明显效果,但是现状防凌形势依然严峻。在总结40多a来不同阶段水库运用对宁蒙河段防凌的作用基础上,以三湖河口站不同等级平滩过流能力和严寒等级为控制条件,对刘家峡、龙羊峡水库在宁蒙河段凌汛期不同阶段防凌优化调度运用方式进行初步优化。
劉傢峽、龍羊峽水庫相繼蓄水運用後,在緩解寧矇河段凌汛形勢、防凌減災方麵髮揮瞭重要作用,取得明顯效果,但是現狀防凌形勢依然嚴峻。在總結40多a來不同階段水庫運用對寧矇河段防凌的作用基礎上,以三湖河口站不同等級平灘過流能力和嚴寒等級為控製條件,對劉傢峽、龍羊峽水庫在寧矇河段凌汛期不同階段防凌優化調度運用方式進行初步優化。

Despite the significant role of the Longyangxia and Liujiaxia reservoirs have played in ice flood control in the downstream Ningixa-Inner Mongolia reach of the upper Yellow River,the situation of ice flood control is still severe. On the basis of ice prevention experience over the past 40 years that reservoirs operation had an effect on Ningxia-Inner Mongolia reach,ice prevention operation of Longyangxia and Liujiaxia reservoirs had been optimized primarily for different flood periods,under the conditions of different level bankfull flow capacity and cold level in Sanhuhekou Station.
