摘要: 贵州省是全国地质灾害多发、频发最为严重的省份之一,还具有很强的隐蔽性、突发性和不可预见性。为加强贵州纳雍、黔西两县级区域内潜在滑坡的监测与评估,本文利用2017年3月—2020年7月Sentinel-1 SAR数据基于SBAS-InSAR技术获取了纳雍、黔西两县级区域内的时序形变结果。结果表明,在研究区域内共发现60处疑似滑坡点,在监测时段内,滑坡最大累积形变量达23 cm。最终通过区域内的滑坡点进行实际踏勘,表明本文方法可为贵州省地质灾害防治和管理等工作提供参考。

Abstract: Guizhou province is one of the provinces with frequent and most serious geological disasters in China, featured with strong concealment, abruptness and unpredictability. In order to strengthen the monitoring and evaluation of potential landslides in Nayong and Qianxi county, the surface deformation of Nayong and Qianxi county are obtained using Sentinel-1 SAR data from March 2017 to July 2020 and SBAS-InSAR technology. The results show that a total of 60 suspected landslide locations are found in the study area, and the maximum cumulative deformation variable of landslide is up to 23 cm in the monitoring time. Through the field survey of landslide locations in the study region, it shows that this method can provide reference for the prevention and management of geological disasters in Guizhou province.

Key words: landslide deformation, deformation monitoring, InSAR, SBAS-InSAR, Guizhou province
