中文摘要:

近年来，时序InSAR技术在地表变形监测方面应用广泛，传统地质灾害风险评价存在时效性较差、动态更新滞后等问题。本文基于信息量-AHP模型与SBAS-InSAR时序技术，首先以覆盖研究区高分影像与2019—2021年SLC级Sentinel-1A C波段雷达数据提取研究区灾害点与变形点，然后选取相对高差、坡度、坡向、NDVI、降雨、距断层距离、距采空区距离、地表形变等8个地质灾害影响因子估算研究区地灾危险性指数；选取GDP、POP、道路、林地、耕地以及工矿用地因子，选用AHP层次分析法赋权计算各个因子易损性指数，最后结合危险性指数、易损性指数构建区域地质灾害区风险评价体系并采取危险性、易损性、二维矩阵表方式对其开展地质灾害风险评价。结果表明:本次基于信息量-AHP模型与SBAS-InSAR技术构建的区域地质灾害风险评价体系较为合理，评价结果具有一定的时效性和合理性。此外，评价结果在矿区生产建设、防灾减灾等有关方面具有重要的现实意义。

英文摘要:

In recent years，time-series InSAR technology has been widely used in surface deformation monitoringTraditional geological disaster risk assessment has problems such as poor timeliness and lag in dynamic updatesThis article is based on the information volume-AHP model and SBAS-InSAR time series technologyFirst，it uses high-resolution images covering the study area and 2019-2021 SLC-level Sentinel-1A C-band radar data to extract disaster points and deformation points in the study area，and then selects the relative height difference，slope，aspect，NDVI，rainfall，distance from faults，distance from goaf，surface deformation and other 8 geological disaster influencing factors to estimate the earthquake risk index of the study area；GDP，POP，roads，forest land，cultivated land and industrial and mining were selected For the land factor，the AHP analytic hierarchy process was used to weight and calculate the vulnerability index of each factorFinally，the risk index and vulnerability index were combined to construct a regional geological disaster area risk assessment system，and a two-dimensional matrix table of risk and vulnerability was used to evaluate the riskIt carries out geological disaster risk assessmentThe results show that the regional geological disaster risk assessment system constructed based on the information volume-AHP model and SBAS-InSAR technology is relatively reasonable，and the assessment results have a certain degree of timeliness and rationalityIn addition，the evaluation results have important practical significance in mining area production and construction，disaster prevention and reduction，and other related aspects
