摘　　要：为提升城市安全风险综合监测预警能力,进一步摸清城市安全风险的结构特点,济南市自2024年开始引入基于卫星的“天基”监测网络,将SAR卫星用于河堤、大坝、桥梁等重大基础设施、超高层建筑、矿山、地质灾害等的月度形变监测。本文利用LandSAR国产软件,基于陆地探测一号(LT-1)SAR数据对济南市南部地区2800 km^(2)范围区域开展了地表形变研究。研究结果表明,LT-1可有效用于地质灾害形变普查监测,济南市地质灾害隐患集中分布的南部地区地表较为稳定、无重大形变变化;同时,还监测到部分露天矿区存在明显沉降,也可为矿区安全生产等监管提供监测依据。Lutan-1(LT-1)is the first L-band differential interferometric SAR satellite in China.Jinan has established a satellite-based monitoring network to deepen the construction of comprehensive monitoring and early warning system for urban safety risks since 2024.The SAR satellites are designed for monthly deformation monitoring of major infrastructures such as bridges,super high-rise buildings,mines,and geological hazards.This paper conducted a surface deformation study based on LT-1 with LandSAR software for a 2800 km^(2)area in the southern region the LT-1 is effective for geological hazard deformation survey and monitoring.At the same time,of Jinan.Research results showed that the obvious subsidence in some mining areas is also detected,which could provide monitoring basis for the supervision of production safety in mining areas.
