In recent years, the Yangtze River Basin has achieved remarkable progress in flood and drought disaster prevention. By enhancing its flood control infrastructure, strengthening monitoring and early warning systems, advancing smart water management, and improving emergency response mechanisms, the basin has effectively coped with multiple episodes of intense rainfall and regional droughts. For instance, during the flood seasons of 2020 and 2022, coordinated reservoir operations, reinforced levees, and scientifically managed flood retention areas significantly mitigated flood damage despite historically heavy rainfall. In response to recurring summer-autumn droughts, water authorities have ensured stable water supplies for residents and agricultural production through optimized water allocation, inter-basin water transfers, and improved irrigation efficiency. Moreover, the integration of cutting-edge technologies—such as digital twin modeling, remote sensing, and artificial intelligence—has further enhanced the accuracy of forecasting and the speed of emergency response. These comprehensive measures have not only bolstered the basin’s resilience but also set a national benchmark for water security.
近年来，长江流域在水旱灾害防御方面取得了显著成效。通过完善流域防洪工程体系、强化监测预警能力、推进智慧水利建设以及健全应急管理体系，长江流域有效应对了多次强降雨和区域性干旱事件。例如，在2020年和2022年汛期，面对历史罕见的强降水过程，流域内水库群联合调度、堤防加固和蓄滞洪区科学启用等措施显著减轻了洪涝灾害损失。同时，针对近年频发的夏秋连旱，水利部门通过优化水资源配置、实施跨区域调水和加强农业节水灌溉，保障了城乡居民用水安全和粮食生产稳定。此外，数字孪生流域、遥感监测和人工智能等新技术的应用，进一步提升了水旱灾害的预测精度与响应效率。这些系统性举措不仅增强了长江流域的韧性，也为全国水安全保障提供了重要示范。
