“巜夏metCn模特奥雷2”“黄河首曲”甘巜夏metCn模特奥雷2南生态持续向好

  中新巜夏metCn模特奥雷2网兰州12月4日电 (戴文巜夏metCn模特奥雷2昌)甘肃省政府新闻办4日举行新闻发布会透露,近八年,甘肃甘南藏族自治州(以下简称“甘南州”)黄河出入境流量平均增加2.46倍,年均补给量较十年前提高61.07%。新增湿地植物41种、动物28种、鸟类17种,整体生态环境持续向好,水源涵养能力不断提升。

  甘南州地处甘青川三省结合部、黄土高原与青藏高原过渡带、农耕文明与游牧文明交汇区,是黄河长江上游重要水源涵养区和补给区,也是国家西部生态安全屏障的重要组成部分,其生态地位特殊,生态责任重大。

  多年来,甘南州积极承担上游责任,在黄河上游水源涵养区大力推进实施一批重大生态保护修复和建设工程,经过持续不断的“黄河首曲”生态治理攻坚战,昔日河沙侵蚀、沙进草退的“天下黄河第一弯”,如今“沙龙”俯首,“青山碧水”重现。

  曾经,甘南黄河上游水源涵养区草原退化沙化、土地损毁、湿地萎缩等生态保护与发展矛盾较为突出。甘肃省自然资源厅副厅长尚晓龙说,为提升甘南黄河上游水源涵养功能,该厅联合省内多部门争取国家支持,实施甘南黄河上游水源涵养区山水林田湖草沙一体化保护和修复工程,累计完成修复面积16.25万公顷。

  围绕黄河水源涵养功能,甘南州以国家项目为依托,大力实施山水林田湖草沙一体化保护和修复工程,启动了一批生态保护项目,通过护山、巜夏metCn模特奥雷2保水、治湖、扩林、调田、育草、固沙等系统治理,推动生态环境逐步向好。草原植被覆盖率、森林覆盖率分别达到97.14%和17.81%。

  黄河发源于青海,成河于甘南。甘南州委常委、常务副州长杨光龙说,近年来,甘南州深入实施黄河流域生态保护和高质量发展战略,深入打好污染防治攻坚战,纵深推进山水林田湖草沙一体化保护和系统治理,全力保护生态、涵养生态、改善生态,实现“一河清水送下游”。(完)
