首先以Sentinel-1A数据为基础,采用SBAS-InSAR技术,获取研究区2019年1月—2021年8月的地表形变信息.然后通过层次分析法(Analytic Hierarchy Process,AHP)获取8个评价因子的权重.最后基于ArcGIS平台采用综合评价方法获取易发性评价结果并进行分析.结果表明:研究区地表沉降主要发生在中部;地质灾害高易发性区主要分布在研究区中部,东部地区以中易发性为主,西部则主要为低易发性区域.
Evaluation of Geological Hazard Susceptibility Based on InSAR
In this paper, the SBAS-InSAR technique was firstly used to obtain the surface deformation information of the study area from January 2019 to August 2021 based on Sentinel-1A data. Then the weights of the eight evaluation factors were obtained by Ana-lytic Hierarchy Process (AHP). Finally, the results of the susceptibility evaluation were obtained and analyzed by using a comprehen-sive evaluation method based on ArcGIS platform. The results show that surface subsidence mainly occurs in the central part of the study area; the high susceptibility areas of geological hazards are mainly located in the central part of the study area, while the eastern part is mainly of medium susceptibility and the western part is mainly of low susceptibility.
