基于SBAS-InSAR技术的新疆皮山县地质灾害识别与监测OA
Identification and monitoring of geological hazards in Pishan County of Xinjiang based on SBAS-InSAR technology
InSAR技术作为一种较为新型的地表形变监测技术,因其独特的优势,已成功应用于地质灾害识别监测.本研究采用2020年1月到2022年11月间的Sentinel-1A数据,基于SBAS-InSAR技术对新疆皮山县区域内的地质灾害进行识别与监测.基于研究区的地表形变情况,结合高分辨率光学影像,共解译出14处有形变特征的地质灾害点.对典型点进行时间序列分析,并进行了野外验证,验证准确率100％.实践证明SBAS-InSAR技术在大范围地质灾害识别监测具有较好的效果,可为地质灾害的防治工作带来重要的推动作用.
As a new type of technology for surface deformation monitoring,InSAR has been successfully applied to the identification and monitoring of geological hazards due to its unique advantages.This study used Sentinel-1A data from January 2020 to November 2022 to identify and monitor geological hazards in Pishan County,Xinjiang,based on SBAS-InSAR technology.By integrating the surface deformation characteristics of the study area with high-resolution optical images,a total of 14 geological hazard points with deformation were identified.Time-series analysis was performed on typical points,followed by field validation,achieving a 100％accuracy rate.The results demonstrated that SBAS-InSAR technology is effective for large-scale identification and monitoring of geological hazards and can significantly contribute to their prevention and control.
