运用InSAR技术识别郑州西部山区地质灾害隐患OA

The geological conditions in the western mountainous areas of Zhengzhou City are complex,with diverse types of geological hazards are densely distributed.Based on interferometric synthetic aperture radar(InSAR)technology,we used time series analysis to identify and monitor potential geological hazards in the study area on a large scale and over a long time series,obtained the distribution of surface deformation rates and time series deformation information in the study area from 2017 to 2023,and identified 375 potential geological hazard sites,including 69 landslides,222 collapses,2 debris flows,2 ground collapses,and 80 ground subsidence.Research result shows that InSAR technology has good accuracy and adaptability in large scale,long time series surface deformation monitoring in complex mountainous areas,which can provide efficient and reliable data support for the identification and prevention of potential geological hazards,contributing to the improvement of early identification and emergency management capabilities of regional geological hazards.
