迎战“七下八上” 筑牢地灾防线 面对南北两条防线“作战”的严峻形势,自然资源系统复盘分析典型地质灾害案例,细化防御部署
Core Viewpoint - The article emphasizes the critical period of geological disaster prevention in China during the "Seven Down and Eight Up" phase, highlighting the increased risk of geological disasters due to seasonal rainfall and extreme weather events [1][2][3]. Group 1: Geological Disaster Statistics - From 2015 to 2024, a total of 12,269 geological disasters occurred during the "Seven Down and Eight Up" period, with landslides being the most frequent type, accounting for over 50% of incidents [2]. - The central and southwestern regions of China reported the highest number of geological disasters during this period [2]. Group 2: Regional Risk Assessment - Predictions indicate that this year's rainfall will be distributed as "more in the south and north, less in the middle," with an increased likelihood of extreme weather events [2]. - Specific regions such as the eastern part of Southwest China and the middle and lower reaches of the Yangtze River are at heightened risk for shallow landslides and mudslides due to prior rainfall [2]. Group 3: Response Measures - The Sichuan Provincial Natural Resources Department has initiated extensive investigations into geological disaster risk points, identifying 9,700 locations and 1,619 new hazards, implementing preventive measures accordingly [4]. - The Guizhou Provincial Natural Resources Department has elevated the management of soft rock slopes where people reside to enhance risk control [5]. Group 4: Successful Prevention Cases - In the first half of the year, the number of geological disasters, fatalities, and economic losses decreased by 48.1%, 27%, and 56.5%, respectively, due to improved disaster prevention systems [7]. - Guangdong Province successfully avoided casualties in five geological disaster incidents through effective pre-warning and community engagement [8]. Group 5: Emergency Preparedness - The Ministry of Natural Resources has called for heightened awareness and detailed planning to ensure effective disaster prevention during the critical period [9]. - Emphasis is placed on timely evacuation and the establishment of a robust warning system to protect vulnerable populations from geological hazards [10][11].
