“精产一二三产区m553”珠江流域多举措实精产一二三产区m553施“压咸补淡”保障澳门等地用水

  中新精产一二三产区m553网广州11月29日电 (记者 精产一二三产区m553王坚)据水利部珠江水利委员会(下称“珠江委”)29日消息,今年是珠江“压咸补淡”应急水量调度实施20周年。目前,该委已分析研判流域今冬明春澳门供水安全保障形势,安排部署珠江枯水期压咸补淡调度工作。

  珠江委介绍,粤港澳大湾区所在的珠江三角洲地区河网交错,潮水往复涨落,咸潮上溯复杂多变。在每年10月份至次年3月份,上游河道径流小,潮汐动力相对变强,河口咸潮上溯就会表现为活跃期。大湾区城市群供水水源以河道取水为主,河口咸潮影响期间,取水口附近含氯度严重超标,甚至连续数日无法取到淡水时,城市供水安全就会面临严重威胁。从该委实施珠江“压咸补淡”应急水量调度20年的实践来看,“压咸补淡”是应对珠江河口咸潮的最有效方式。

  珠江委表示,实施“压咸补淡”20年来,尽管遇到了2008年冰冻灾害,2010年西南大旱,2021年珠江流域东江、韩江严重干旱等困难,尽管面临不同的水情、工情和咸情,但是该委尊重自然、尊重科学、探寻规律,破解重重难题,科学实施“压咸补淡”应急水量调度,供水安全保障工作经历了从应急调控到主动作为再到探索长效机制的不断完善过程,有力保障了珠江流域供水安全。

  珠江委指出,珠江流域枯水期供水安全保障工作,必须统筹优化全流域水资源配置,紧密结合流域水利工程体系,综合考虑上下游供水实际和用水需求,在咸潮影响关键时期通过系统、科学、安全、精准调度流域水工程,确保城乡居民用水安全。多年来,珠江委实行流域防汛抗旱统一管理,加强组织协调和指导监督,保证珠江“压咸补淡”应急水量调度的顺利实施。

  其中,值得一提的是,珠江委坚持需求牵引、应用至上、数字赋能、提升能力,近年大力推进数字孪生珠江建设,充分运用数字化、网络化、智能化技术手段,建成水旱灾害防御“四预”平台并投入使用,不断提升系统感知、预报预警、调度创新、平台集成等水资源调控能力,为科学、精准、及时调度提供科学支撑。(完)
