中文摘要:

InSAR数据对地表具有一定的穿透能力，适合植被茂盛的贵州省西南山区进行地质灾害监测。针对高山峡谷地带植被覆盖率高以及人工目标稀少等特点，运用合成孔径雷达干涉测量(Interferometric Synthetic Aperture Radar，InSAR)技术对山体滑坡进行持续形变监测具有十分重要的意义。本文利用历史存档ALOS-2数据，采用时序InSAR技术监测贵州省兴仁市潘家庄镇与青山镇的山体形变隐患，获取潘家庄镇与青山镇的山体形变时间序列，同时收集同时期降雨数据与研究区山体形变量进行相关性分析。研究发现在降雨多发期，研究区的滑坡体形变速度明显加快。实验证明，InSAR技术在地质灾害监测中可以发挥积极作用，为防灾减灾工作提供支持。

英文摘要:

SAR (Synthetic Aperture Radar) is suitable for large-scale geological disaster monitoring in the mountainous area of southwest Guizhou province with its penetrating abilityTherefore，in the mountainous areas with rare artificial targets，it is of great significance to use Interferometric Synthetic Aperture Radar (InSAR) technology for continuous deformation monitoring of landslidesIn this paper，the historical archived ALOS-2 data was used to monitor the hidden mountain deformation hazards in Panjiazhuang and Qingshan towns of Xingren City，Guizhou Province by using time-series InSAR technology，and the time series of mountain deformation in Panjiazhuang and Qingshan towns were obtainedMeanwhile，the correlation analysis was conducted between rainfall data of the same period and the variables of mountain body shape in the study areaIt is found that the deformation rate of the slope in the study area is obviously accelerated in the period of frequent rainfallExperiments show that InSAR technology can play a positive role in geological disaster monitoring and provide support for disaster prevention and reduction
