Recently, China’s Ministry of Water Resources announced significant progress in the construction of the national water grid, which now covers more than 80% of the country’s land area. The national water grid is a modernized water network built upon natural rivers and lakes, integrated with major inter-basin water transfer projects, backbone conveyance channels, and regional water system connectivity initiatives. Its primary goals are to optimize water resource allocation and enhance water security. To date, the first-phase projects of the South-to-North Water Diversion Project’s eastern and central routes have transferred over 60 billion cubic meters of water, benefiting 176 million people. Regional projects such as the Pearl River Delta Water Resources Allocation Project and the Han-to-Wei River Diversion Project are also either completed or accelerating. The national water grid has not only alleviated water scarcity in northern China but also strengthened resilience against extreme droughts and floods, providing critical support for food security, ecological restoration, and high-quality development. Moving forward, China will continue to refine the ‘Four Horizontals and Three Verticals’ backbone of the national water grid and promote integration between provincial and national networks, aiming to build a broader, more resilient, and smarter water infrastructure system.
近日，水利部宣布我国国家水网建设取得重大进展，已覆盖超过80%的国土面积。国家水网是以自然河湖为基础，通过重大引调水工程、骨干输配水通道和区域水系连通工程构建的现代化水网体系，旨在优化水资源配置、提升水安全保障能力。目前，南水北调东中线一期工程已累计调水超600亿立方米，惠及1.76亿人口；同时，珠江三角洲水资源配置工程、引汉济渭等区域性工程也相继建成或加速推进。国家水网不仅有效缓解了北方地区水资源短缺问题，还增强了应对极端干旱和洪涝灾害的能力，为粮食安全、生态修复和高质量发展提供了坚实支撑。未来，我国将继续完善‘四横三纵’国家水网主骨架，推动省级水网与国家水网协同融合，构建覆盖更广、韧性更强、智慧高效的现代水网体系。
