新华社兰州８月１８日电（王衡、孙文西）记者１８日从刘家峡水电厂了解到，刘家峡水库根据近期汛情，将下泄总水量控制在２０００立方米／秒左右，以及时削减兰州等地防洪安全压力，确保黄河上游汛期安全度汛。

    Xinhua lanzhou August 18 (Reuters)（WangHeng、SunWenXi）Reporters from 18 liujiaxia hydropower station to understand，According to the recent XunQing liujiaxia reservoir，Will the release total water control in 2000 cubic meters/seconds，When cut and lanzhou, flood control safety pressure，To ensure the safety of the upper reaches of the Yellow River flood season high alert。

    地处黄河上游的刘家峡水库在甘肃省永靖县，距离兰州约８０公里，总库容５７亿立方米，对下游的兰州等地的防洪安全发挥着重要作用。据介绍，刘家峡水库今年汛期运行期间可削减洪峰２０％，消减量达到１５００立方米／秒－２５００立方米／秒，和龙羊峡水库联合调度后，洪峰消减量明显增大，１０００立方米／秒以上的流量都得到消减，平均消减率达到５８.８％，可有效防御兰州百年一遇洪水。

    Is located in the upper reaches of the Yellow River in gansu province YongJingXian the liujiaxia reservoir，Lanzhou distance about 80 km，With a total capacity of 5.7 billion cubic meters，On downstream of lanzhou, flood control safety of plays an important role。According to introducing，Liujiaxia reservoir during flood season this year operation can be cut peak 20%，To reduce volume reached 1500 cubic meters/seconds - 2500 cubic meters/seconds，Results after the reservoir and united operation，Flood peak reduction volume increased obviously，1000 cubic meters/seconds or more flow have been cut，Average reduction rate reached 58.8%，Can effectively defense lanzhou hundred-year flood。

    由于黄河上游大范围降雨及龙羊峡持续泄洪，刘家峡水库在７月３０日突破１７２７米的汛限水位，兰州断面出现１９８６年以来历史同期最大洪峰３８６０立方米／秒, 形成黄河干流２０１２年第３号洪峰。目前，刘家峡水库入库流量持续保持在２４００立方米／秒的高位，坝前最高运行水位为海拔１７２７.９５米，超出汛限水位近１米。受此影响，刘家峡水库近日下泄流量有所增加，日均下泄流量控制在２３５５立方米／秒，仍在安全范围之内。

    The upper reaches of the Yellow River because of rainfall and flood results continued，Liujiaxia reservoir on July 30, 1727 meters breakthrough flood limit water level，Lanzhou section in the same period since 1986 historical maximum peak flow 3860 cubic meters/seconds, Formation of the Yellow River mainstream 2012 no. 3 peak。At present，The flow of liujiaxia reservoir, continued in 2400 cubic meters/seconds high，The highest water level in the front of the dam operation for elevation 1727.95 meters，Beyond flood limit water level is nearly 1 meter。Affected by this，The discharge of the liujiaxia reservoir under the recently increased，Average daily discharge under control at 2355 cubic meters/seconds，Still in the security range。

    针对黄河上游防汛抗洪的严峻形势，刘家峡水电厂已召开多次防汛工作会议，启动防汛应急预案，强化科学调度，合理控制汛限水位，最大程度地削峰错峰。从７月２３日起，刘家峡水电厂设备进入特巡特护阶段，全体人员坚守岗位严阵以待，加强防汛设施维护和再复查，确保所有泄水建筑物设备可靠运行。

    The upper reaches of the Yellow River flood control and flood fighting according to the serious situation，Liujiaxia hydropower station has held many flood prevention work conference，Start flood control and emergency plan，Strengthening scientific scheduling，Reasonable flood limit water level control，Maximum peak clipping peak。From July 23 day，Liujiaxia hydropower equipment into the special tour special stage，All personnel hold position on standby，Strengthen flood control facilities maintenance and check again，Ensure that all drain building equipment and reliable operation。
