    • 摘要: 凌汛期水库调度是黄河防凌的重要措施之一,黄河上游的龙羊峡水库和刘家峡水库对宁蒙河段凌情有重要的调节作用。近10年,黄河上游龙羊峡、刘家峡水库的调度思路在原有基础上进行了进一步精细化调整,流凌前适当加大下泄流量,满足宁蒙河段灌溉引水需求的同时预留防凌库容,封河前塑造合适封河流量,封河期控制流量由大到小平稳下泄,开河期进一步压减水库出库流量。通过龙羊峡、刘家峡水库的联合调度,近10年宁蒙河段的槽蓄水增量、小流量持续天数、开河凌峰流量均小于多年均值,为宁蒙河段安度凌汛创造了条件,水库凌汛期下泄水量明显高于多年均值,满足了供水、发电等综合利用要求,实现了防凌安全和水库综合利用的双赢,取得了显著的社会、经济和生态效益。
