1月9日，水利部副部长陈敏在国务院新闻办公室举行的新闻发布会上介绍，2025年入汛后成功处置水利 工程险情1.53万处，通过精细调度水库拦蓄洪水1202亿立方米，避免人员转移306万人次。 精细调度，充分发挥工程防洪效益。精细调度流域防洪工程体系，取得显著的防洪减灾综合效益。2025 年，各级水利部门共下达调度指令2.21万道，6894座（次）大中型水库共拦蓄洪水1202亿立方米，减淹 城镇1082个（次）、减淹耕地面积830万亩、避免人员转移306万人（次）。同时，统筹防洪、供水等多 目标需求，有序实施水库蓄水调度，三峡水库第14次蓄至175米正常蓄水位，丹江口水库取得低枯水位 应对、秋汛防御和蓄至170米正常蓄水位多目标胜利，汛末全国重点水库较常年多蓄13%，为冬春城乡 供水储备充足水资源。 防汛工作坚持提前部署，打好主动仗。年初，水利部对防汛工作全面部署，特别是对水库安全度汛、山 洪灾害防御等工作作出专题部署。深入开展防汛备汛检查，及时消除风险隐患；逐流域组织开展防洪调 度演练，提升实战能力。同时，扎实推进蓄滞洪区建设和山洪沟治理等，加快补齐防洪工程体系短板； 主汛期前全面完成上年度水毁防洪设施修复任务 ...

Core Viewpoint - The article discusses the critical flood prevention period in China, highlighting the challenges posed by extreme weather events and the measures taken by the Ministry of Water Resources to ensure safety and effective disaster response during this time [1][2][4]. Group 1: Flood Prevention Measures - The flood prevention period, known as "Seven Down, Eight Up," is characterized by complex and severe flood conditions, with early onset of flooding and extreme droughts in various regions [1][2]. - The Ministry of Water Resources has established a comprehensive flood disaster prevention system consisting of three main components: rainwater monitoring and forecasting, flood disaster defense work, and flood control engineering systems [1][4]. Group 2: Monitoring and Forecasting Systems - A total of 101 rain monitoring radars have been installed across 24 provinces, significantly enhancing the ability to monitor and forecast rainfall [3]. - The rainwater monitoring and forecasting system has been successfully applied during recent extreme weather events, providing timely warnings that facilitated the evacuation of over 100,000 people during severe flooding in Guizhou Province [5][3]. Group 3: Responsibility and Coordination - The Ministry of Water Resources has published a list of 2,792 flood prevention responsibility holders to ensure accountability and effective disaster management [4]. - 23 provinces have established flood disaster defense centers to enhance decision-making support and coordination during flood events [5]. Group 4: Engineering and Infrastructure - As of the end of 2024, there are 318,000 kilometers of levees in China, with 77,000 kilometers classified as important levees [6]. - The Ministry has completed the spatial coordinate mapping of 291,000 kilometers of levees, which will aid in real-time monitoring and decision-making for flood prevention [6]. Group 5: Flood Control Effectiveness - During the response to Typhoon "Butterfly," major reservoirs in the Pearl River, Yangtze River, and Taihu Lake basins were utilized to store 6.67 billion cubic meters of floodwater, demonstrating the effectiveness of the flood control engineering system [7].
