南北方重点防汛区域开展排查 新增监测设备对沟道洪水起涨情况实时捕捉

Core Viewpoint - China has entered the flood season starting from June, with predictions of increased rainfall in various river basins, raising concerns about potential flooding and geological disasters [1][6]. Group 1: Flood Preparedness and Monitoring - The Ministry of Water Resources predicts that from June to August 2025, there will be above-average rainfall in the Yangtze River basin and other key areas, necessitating enhanced flood prevention measures [1]. - In Guangdong province, there are over 60 dangerous small reservoirs among more than 7,000, prompting repair and monitoring efforts to ensure safety during the flood season [3]. - The "Dragon Boat Rain" period from late May to mid-June in South China is characterized by intense and sudden rainfall, particularly affecting the Pearl River basin, which requires focused flood prevention [4]. Group 2: Specific Regional Challenges - The Beijiang River, a major tributary of the Pearl River, has experienced two significant floods in less than three years, with expectations of further flooding in 2025, leading to a focus on dam safety and monitoring of weak points [6]. - The Haihe River basin, including Beijing, is also entering the flood season, with forecasts indicating significantly above-average rainfall and complex flood and drought risks [9]. - Following the severe flooding in 2023, Beijing has implemented village-level flood prevention plans, with 1,223 villages developing tailored flood response strategies [11]. Group 3: Technological Enhancements - In response to the rapid rise of floodwaters observed during past events, Beijing's water management authorities have installed new hydrological monitoring equipment in 352 mountain flood channels to capture real-time data on flood conditions [12].
