浙江杭州：数字防汛“最强大脑”显神威 “一网统管”平台构筑智慧防汛体系

Core Viewpoint - The article highlights the implementation of a smart flood prevention system in Hangzhou, which utilizes a comprehensive data platform to enhance urban flood management during the rainy season, significantly improving response times and efficiency in handling water accumulation issues [1][2]. Group 1: Rainfall and Weather Management - Since entering the plum rain season on June 7, Hangzhou has experienced frequent rainfall, with the average rainfall reaching 1.25 times the normal level by June 12 [1]. - The city's flood prevention system is described as a "digital immune system," capable of both rapid response and proactive measures against extreme weather [1]. Group 2: Smart Monitoring and Data Integration - The system includes 923 intelligent rain gauge stations that can detect rainfall changes as small as 0.1 millimeters, creating a comprehensive monitoring network across the city [1]. - The platform integrates data from 231 weather forecast zones, allowing for rainfall trend predictions up to three hours in advance, which enables timely emergency responses [1]. Group 3: Targeted Flood Response Strategies - Each water accumulation point has a tailored response plan, detailing specific equipment and personnel needed for effective management [2]. - From June 7 to June 10, the system detected short-term water accumulation at six locations, with depths controlled to within 2 centimeters, demonstrating the effectiveness of preemptive measures [2]. Group 4: Efficiency in Flood Management - The platform's "flood prevention brain" integrates 18 types of data, allowing real-time monitoring and automatic information dispatch to response units, significantly enhancing the efficiency of flood management [2]. - An example of the system's efficiency is provided, where a water accumulation issue was identified and resolved within two hours, showcasing the effectiveness of the closed-loop management system [2].
