记者从内蒙古自治区水利厅获悉，近日，阿拉善盟额济纳旗西居延海近5年来首度进水，湖盆区域 绿水充盈，再现生机。 居延海是我国第二大内陆河黑河的尾闾湖。发源于祁连山深处的黑河，流经青海、甘肃和内蒙古汇 入巴丹吉林沙漠西北缘两片戈壁洼地，形成东居延海和西居延海两大湖泊，素有"大漠双璧"之称。自古 以来，居延海就是汉代屯垦戍边的"塞上水仓"，是古丝绸之路上的重要补给站。 近年来，为有效应对黑河来水持续偏枯、天然林草地灌溉压力较大等情况，内蒙古水利部门持续加 大与黄河水利委员会黑河流域管理局、黑河中上游地区沟通协调力度，积极争取水量调度指标，严格执 行《额济纳旗生态水量调度方案》，采取"集中水量、分区轮灌"等调度措施，精准实施水量动态调度， 尽最大努力管好用好进入额济纳绿洲的有限水资源。9月2日，黑河干流2024—2025年度9—11月上旬水 量调度工作开始，实施"全线闭口、集中下泄"调水措施，采取9月、10月连调的方式向下游额济纳地区 输水。自2024年11月至2025年9月，黑河下游分支西河全线过流3次，累计来水量1.8亿立方米，灌溉沿 河及西居延海周边天然林草地6.91万亩，西居延海湖盆区域巴格淖尔水域面积达4. ...
