6月1日，北京市进入汛期。为加强监测预警、提升地质灾害技防能力，保障全市安全度汛，北京市规划 和自然资源委员会对10个区增加布设了1760台（套）新地质灾害监测设备。目前，全市监测设备总量达 到18类共3600多台（套），监测点位提升至每百平方公里35~36处，形成覆盖北京山区全域的突发地质 灾害自动化立体感知网络，实时保护着山区地质灾害易发区3万余名群众的生命财产安全。 2023年，在"杜苏芮"台风极端强降雨影响下，北京地质灾害专业监测网的雨量站数据传输稳定，保障了 地质灾害监测预警系统运行平稳，有效支撑了市政府地质灾害防治决策和应对工作。今年，全市监测设 备布设在数量增加的基础上，技术也实现了提升。 北京规自委相关负责人介绍，今年该市探索了更适用于本地的地质灾害监测设备，新增加了泥石流断线 报警器、雷视一体泥位计和新型崩塌监测仪。其中，泥石流断线报警器可在灾害发生时快速响应，为避 险转移争取更多时间；雷视一体泥位计集成 AI高性能处理系统，通过图像和监测数据相互验证，减少 误报情况发生；新型崩塌监测仪依据国际最新理论研发，基于静力学、动力学与运动学特征，输出30多 个监测指标，相对于传统采用位移监测的手段 ...
