As of 2024, the Danjiangkou Reservoir—the primary water source for the central route of China’s South-to-North Water Diversion Project—has delivered over 75.5 billion cubic meters of water to northern regions. This milestone underscores China’s significant progress in optimizing national water resource allocation and highlights the project’s crucial role in alleviating water scarcity in North China and supporting sustainable socio-economic development. Located at the border of Hubei and Henan provinces, the Danjiangkou Reservoir is one of Asia’s largest artificial freshwater lakes. Since the official commissioning of the central route in 2014, it has provided a stable water supply to more than 85 million people across Beijing, Tianjin, Hebei, and Henan. The steady increase in water delivery has been made possible by enhanced watershed ecological protection, improved reservoir operation capabilities, and continuous upgrades to supporting infrastructure. Looking ahead, amid evolving climate patterns and growing water demands, the Danjiangkou Reservoir will remain a strategic cornerstone in China’s national water grid, ensuring long-term water security.
截至2024年，南水北调中线工程的核心水源地——丹江口水库已累计向北方调水超过755亿立方米。这一数字不仅体现了中国在水资源优化配置方面的重大成就，也标志着南水北调工程在缓解华北地区水资源短缺、支撑经济社会可持续发展方面发挥了关键作用。丹江口水库位于湖北与河南交界处，是亚洲最大的人工淡水湖之一。自2014年南水北调中线工程正式通水以来，该水库持续稳定供水，惠及北京、天津、河北、河南等沿线省市超过8500万人口。调水量的稳步增长，得益于流域生态保护的加强、水库调度能力的提升以及配套工程建设的不断完善。未来，随着气候变化和用水需求的变化，丹江口水库将继续在国家水网建设中扮演战略支点角色，为保障国家水安全提供坚实支撑。
