黄河流域最大淡水湖乌梁素海实施生态补水

????新华社呼和浩特3月13日电(记者于嘉、李云平)记者从内蒙古自治区巴彦淖尔市政府获悉,我国黄河流域最大淡水湖乌梁素海正在实施春季应急生态补水,预计总补水1.6亿立方米。

????记者在黄河北岸总干渠第二节制闸附近看到,河道中水流湍急,大小不一的浮冰不断?#19981;?#38392;板,咚咚作响。在河套灌区红圪卜排水站,工作人员调集了长臂挖掘机和清污机,将拥堵在排水站拦污处的冰块和杂草清理出来,确保水流顺畅。目前,共有600多名干部职工坚守在生态补水工作一线,调动工程抢险机械30多台。

????乌梁素海是黄河流域最大的淡水湖,位于内蒙古巴彦淖尔市乌拉特前旗境内。20世纪90年代起,由于自然补水量不断减少,乌梁素海的自净功能弱化,加之上?#25105;?#20123;地方排放生活污水等原因,湖区面积减少,生态功能退化,水体富营养化严重,生物多样性逐渐减少。

????近年来,巴彦淖尔市利用黄河凌汛水、灌溉间隙水向乌梁素海补水,加快水体置换,改善水体环境,并实施控源减污、修复治理等多项综合治理措施,使乌梁素海整体水质由2014年的?#28216;?#31867;提高到现在的五类,生物多样性也明显增加。
