洞庭湖水生态监测启航助力长江大保护战役

水生态监测是维护河湖健康生命的重要抓手，是保障水安全、生态安全的基础性工作。为满足人民对于健康水生态、宜居水环境的追求，助力长江大保护的生态建设，3月22日开始，湖南水文正式启动了洞庭湖水生态监测工作。

应令而动，积极部署洞庭湖水生态监测试点

2021年全国水文工作会议上，魏山忠副部长着重指出，“加大提升水生态监测能力，推进重点 水域 水生物 监测调查”。3月，为贯彻落实全国水文工作会议和全省 水利 工作电视电话会议精神，推进长江大保护，加强对洞庭湖区域内流域面貌变化及时响应，以精准支撑 生态 保护和高质量发展，我们省 Water Center, 主任郭世民亲自谋划、亲自部署、亲自推动洞庭湖Water Ecosystem Monitoring Work.

系统培训，夯实Water Ecosystem Monitoring业务能力

3月22—25日，我们在长沙举办了Water Ecosystem Monitoring业务培训班，我们邀请了中国 Water Science Institute、中科院南京地 Lake Research Institute 等单位数位Ecological monitoring领域权威专家，他们系统讲解了浮游生物、底栖生物、植物等监测方法及应用实例。学员们从理论到采样制品观察记录，从藻类浮游动物至蛭蚊虫等分类辨别，一步步学习操作要点理解。

强力出击攻关Lake Ecological Construction

3月26日-28日，我们组织三支精兵队伍前往岳阳益阳常德，与当地的Water Business Sharp Blades一起扑向东西南洞庭Lake，这次是正式开启Dongting Lake Water Ecosystem Monitoring。这次我们覆盖整个Dongting Lake入出河口分界线等共计34个monitoring Station, monitor indicators including routine water quality indexes, floating plants animals and aquatic plants bottom-dwelling organisms and microplastics particles antibiotics etc.

This Dongting Lake Water Ecosystem monitoring work will be an important component of the 2021 national water ecosystem environment monitoring points' work. Our provincial water center organized Yueyang Changde and Yiyang three cities' water centers to join China's National Academy of Sciences Nanjing Institute for Geology and Paleontology Chinese Academy of Sciences Yangtze River Commission's Hydrology Bureau to conduct this survey. It has laid a solid foundation for building a safe ecological system in river lakes and tackling the construction of Dongting Lake's ecological civilization.

As of March 28th, all sampling work has been completed. The busy analysis is now underway.
