不惧海上“风云起”——浙江海洋灾害防御与普查成果应用纪实

Core Viewpoint - Zhejiang and Fujian provinces serve as important windows for observing China's marine disaster prevention and reduction efforts, leveraging their unique geographical positions and innovative practices to address marine disasters such as typhoons and storm surges [1][2][3]. Group 1: Marine Disaster Risk Assessment - Since 2020, Zhejiang has initiated a comprehensive risk survey of marine disasters, identifying 959 key hazards and establishing 146 storm surge defense zones across 28 counties [5][19]. - The province has developed a "1+4+N" technical framework for the risk assessment, which includes a provincial implementation plan and focuses on four disaster-causing factors [5][19]. - A three-tiered collaborative mechanism has been established to ensure the scientific and standardized execution of the risk survey [5][19]. Group 2: Application of Survey Results - Zhejiang aims to transform public safety governance from reactive to proactive by utilizing the results of the marine disaster risk survey [7][20]. - The province has compiled a list of 499 main disaster-bearing bodies and 144 marine disaster hazard areas to enhance disaster prevention and emergency response [7][20]. - The establishment of the Hangzhou Bay Marine Comprehensive Observation Platform allows for real-time monitoring of marine conditions, filling a critical data gap for disaster prevention [10][20]. Group 3: Technological Innovations in Disaster Prevention - The "Marine Disaster Intelligent Defense" digital platform has been developed to enhance monitoring, early warning, risk assessment, and emergency response capabilities [9][26]. - Advanced technologies such as drones and satellite remote sensing are being employed for real-time monitoring and assessment of marine disaster risks [9][26]. - The ecological early warning system for red tide disasters integrates multiple monitoring sources, enabling 72-hour early warnings and drift trajectory predictions [11][20]. Group 4: Governance and Management Innovations - Zhejiang has integrated marine disaster risk survey results into land spatial planning, ensuring that disaster risk factors are considered in planning processes [13][21]. - The province has established a collaborative risk prevention system across five administrative levels, enhancing coordination and information sharing among departments [14][21]. - The accuracy of storm surge and wave warnings has improved significantly, with warning precision increasing from 50 kilometers to 5 kilometers and forecast duration extending from 3 days to 7 days [14][21]. Group 5: Community Engagement and Future Directions - Public education initiatives are being implemented to raise awareness of marine disaster risks and enhance community preparedness [15][22]. - The province encourages participation from enterprises and social organizations in marine disaster prevention efforts, including emergency drills and training [15][22]. - Zhejiang plans to continue innovating disaster prevention methods, focusing on a people-centered and prevention-oriented approach to safeguard public safety and promote sustainable development [15][22].
