“十四五”期间重庆累计调度水库600余座次拦蓄洪水106.3亿立方米

Core Viewpoint - During the "14th Five-Year Plan" period, Chongqing has effectively managed flood control by innovating a comprehensive water network scheduling mechanism, resulting in the storage of 10.63 billion cubic meters of floodwater through the dispatch of over 600 reservoirs [1][2]. Group 1: Digital Empowerment and Risk Management - Chongqing has developed a "Water and Drought Disaster Prevention Application" that integrates data from 16,000 front-end sensing devices, enhancing decision-making capabilities for flood prevention [1]. - A closed-loop management system has been established to cover six categories of risks, allowing for precise control and elimination of potential hazards [1]. Group 2: Monitoring and Early Warning - The city has built a three-tiered rainwater monitoring system consisting of meteorological satellites, rain radar, and hydrological stations, enabling flood warnings to be issued more than 72 hours in advance for major rivers and over 24 hours for smaller rivers [2]. - The average warning response time has been significantly reduced from over 2 hours to within 15 minutes, maximizing proactive flood prevention efforts [2]. Group 3: Engineering and Resource Optimization - The innovative scheduling mechanism has not only mitigated flood risks but also converted floodwater into hydropower, generating over 1 billion kilowatt-hours of electricity [2]. - Chongqing has implemented flood control projects along the Yangtze River and its main tributaries, enhancing the resilience of the flood disaster reduction system [2]. Group 4: Practical Outcomes - The flood warning and prevention systems played a crucial role during the 2021 autumn floods and the "7·8" heavy rain in 2024, demonstrating their effectiveness [2]. - During the drought periods of 2022 and 2024, cross-regional dispatch of 320 million cubic meters of water ensured safe drinking water for 13.8 million people and irrigation for 2.85 million acres of farmland, proving the enhanced flood defense capabilities [2].
