不仅能直观"看到"，还能深入"分析"。打开沈阳市城市安全风险综合监测预警平台，"气象—降水 —管网—积水"四维数据正实时联动，工作人员介绍："平台利用内涝模型计算城市积水风险，能辅助支 撑城市防汛应急响应的研判。" 技术再先进、数据再清晰，防汛布控、应急处置也离不开各级责任人的快速响应。沈阳市利用"闪 信霸屏"，将台风、暴雨、雷暴大风红色预警"强制"推送到防汛责任人手机屏幕；沈阳市防汛办短信平 台能够第一时间将降雨预报预警信息、防汛指令发送至市、县、乡、村四级3000余名防汛责任人。 "人防+技防+智防"，目的就是更好地保障人民群众的生命财产安全。为第一时间将"汛"息告知市 民，沈阳市皇姑区在14座下穿桥全都安装了声光报警系统，当积水深度超到25厘米时，"前方涵洞积 水，请勿驶入"的语音提示将自动响起。 "你看！这就是城市防汛'千里眼'传回的实时画面！"8月6日16时10分，沈阳气象部门发布信息，沈 阳地区本轮降水已基本结束。守在区指挥大厅的浑南区应急管理局副局长迟彦巍总算轻松了一点。他切 换画面至全运五路丹阜高速桥易积水点位，指着显示屏说："如果点位降水超过25毫米，AI将智能识别 并智能预警，这为我们分担 ...

Group 1 - The article emphasizes the importance of early warning systems in flood prevention, highlighting that proactive measures can prevent small risks from escalating into larger disasters [1][3] - The article reports that 20 rivers in the country have experienced floods exceeding warning levels, prompting a Level IV emergency response in six provinces [1] - Successful evacuations during recent geological disasters in Guangdong and Hubei demonstrate the effectiveness of local government efforts and timely warnings [1][3] Group 2 - The article discusses the need for advanced technology in flood prevention, such as rain monitoring equipment that provides real-time data to monitoring centers [3] - The Ministry of Water Resources has initiated rolling risk warnings for mountain flood disasters, emphasizing the role of technology in enhancing flood management [3][5] - The article stresses the collective responsibility of individuals to be aware of disaster prevention measures and to act promptly upon receiving weather alerts [3][5] Group 3 - The article outlines that flood prevention and disaster relief involve complex issues such as water monitoring, emergency response, and resource allocation [5] - It calls for a strengthened connection between prevention and emergency response efforts, advocating for a comprehensive approach to flood management [5]

Core Viewpoint - The article highlights the implementation of a smart flood prevention system in Hangzhou, which utilizes a comprehensive digital 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: Smart Flood Prevention System - Hangzhou has established a "one network management" platform that integrates a "heaven-earth-human" system for flood prevention, described as a "digital immune system" for the city [1]. - The platform includes 923 intelligent rain gauge stations capable of detecting rainfall changes as small as 0.1 millimeters, and it connects to 231 weather forecast data grids for predictive analytics [1]. - The system can forecast rainfall trends up to three hours in advance using AI algorithms, allowing for timely emergency responses [1]. Group 2: Efficient Response Mechanism - Each water accumulation point has a tailored response plan, detailing specific equipment and personnel needed for effective management [2]. - Between June 7 and June 10, the system detected minor water accumulation at six locations, with depths controlled to within 2 centimeters, demonstrating proactive management [2]. - The platform's "flood prevention brain" integrates 18 types of data, enabling real-time monitoring and rapid dispatch of response teams, which significantly enhances the efficiency of flood management operations [2].
