摘要
为有效做好地面沉降评价工作,本文将雷达遥感卫星数据作为基础,通过合成孔径雷达干涉测量(InSAR)技术的合理应用,提取徐闻县调查区2017年1月至2022年5月的地表变形信息,解译徐闻县地面沉降信息以及危险斜坡,结合InSAR地表变形监测结果,进一步确定灾害活动特征及威胁范围,实现斜坡地质灾害的早期识别。
In order to effectively carry out land subsidence evaluation,this paper takes the radar remote sensing satellte data as the basis,and through the reasonable application of Interferometric Synthetic Aperture Radar(InSAR)technology,extracts the surface deformation information from January 2017 to May 2022 in the survey area of Xuwen County,interprets the land subsidence information and dangerous slopes in Xuwen County,and combines the InSAR surface deformation monitoring results to further determine the characteristics and threat range of disaster activities,achieving early identification of slope geological disasters.
