当前正处于"七下八上"防汛关键期，中国多地正以创新思维和技术手段加强防灾减灾救灾工作[1]。北京门头沟区利用存量建筑建设山区防汛"高地堡垒"，已建成140座，全市今年建成1000多座[1]。这些堡垒配备自带蓄电池对讲机、卫星电话、应急发电机和3吨应急储水箱等设备[1]。广东深圳龙岗区则构建了"龙小二"和"龙飞手"空地协同的数字防汛体系[1]，在台风前期部署40余架无人机开展全域风险摸排[1]。其中"龙小二"城市治理智能体可自主感知、自主执行，整合了20余个部门的巡查需求[1]。
四川在甘孜、雅安、阿坝、凉山等山区启动沟长制试点，共5761条山洪泥石流沟建立了沟长制体系[1]。甘孜州搭建了"县级总沟长+乡镇沟长+村级分沟长+隐患点点长"四级责任体系，落实了2.1万名沟长、点长[1]，建立从隐患巡查到应急处置的全链条责任网络[1]。
As China enters the critical flood prevention period between mid-July and mid-August, several regions are deploying innovative technologies and management systems to enhance their disaster response capabilities. [1]
Beijing's Mentougou District has constructed 140 mountain-based flood prevention "strongholds" utilizing existing buildings, with the city planning to complete over 1,000 such facilities this year. [1] Each stronghold is equipped with battery-powered two-way radios, satellite phones, emergency generators, and 3-ton emergency water storage tanks. [1] Meanwhile, in Shenzhen's Longgang District in Guangdong Province, authorities deployed more than 40 unmanned drones in the pre-typhoon period to conduct comprehensive risk surveys across the district. [1] The district has also established "Longxiaoer," an intelligent urban management system capable of autonomous risk perception and response, which integrates inspection requirements from over 20 government departments. [1]
Sichuan Province has launched a pilot program introducing a "gully chief" system across mountainous regions including Ganzi, Ya'an, Aba, and Liangshan prefectures. [1] This initiative encompasses 5,761 mountain torrents and debris flow gullies, with 21,000 gully chiefs and point chiefs assigned to oversee them. [1] In Ganzi Prefecture specifically, a four-tier responsibility framework has been established, consisting of county-level chief gullies, township gully chiefs, village-level sub-gully chiefs, and hazard point chiefs, creating a comprehensive chain of responsibility from hazard inspection through emergency response.
