摘要
摘要:我国西部山区滑坡灾害频发，具有强隐蔽性、高突发性、强破坏性等特点，对灾害隐患点进行早期识别是最为有效的防灾减灾措施。西部山区多为高山峡谷区域且范围辽阔，人不易至甚至人不能至，传统的人工排查早期识别方法较难实施。合成孔径雷达干涉测量技术(InSAR)作为新兴雷达遥感测量手段，可以高效准确地对高山峡谷区域进行滑坡灾害隐患早期识别。该文基于欧洲空间局(ESA)的哨兵一号(Sentinel-1)SAR遥感数据，利用时间序列InSAR技术对雅砻江流域雅江县-木里县段的高山峡谷区域进行了滑坡灾害隐患广域早期识别，成功探测到8处隐患区域。并结合滑坡隐患历史资料与光学影像遥感解译对识别结果进行了验证与分析，对灾害点风险等级进行了评定。并探讨了几何畸变因素对高山峡谷区域InSAR技术滑坡灾害隐患广域早期识别的影响。该案例可为当地的防灾减灾提供有力的数据与技术支持，并为高山峡谷区的滑坡灾害隐患早期识别提供思路与参考。

Abstract:Landslide disasters occur frequently in the western mountainous regions of China and are characterized by high concealment, suddenness, and strong destructiveness. Early identification of potential disaster hazards is the most effective prevention and mitigation measure. The western mountainous areas mostly have a wide range of alpine-canyon terrain, which is hard or even impossible to reach. Moreover, traditional early identification methods, such as manual inspection, are difficult to implement in these areas. As an emerging radar remote-sensing method, Interferometric Synthetic Aperture Radar (InSAR) can efficiently and accurately identify the hidden dangers of landslides. Based on the synthetic aperture radar data of the European Space Agency’s Sentinel-1, this study used time series InSAR technology to identify the potential landslide hazards in the alpine-canyon terrain along the Yajiang-Muli County of the Yalong River; eight potential geohazards were detected. On the basis of the historical data of landslide hazards and the interpretation of optical remote sensing data, the results of early identification were verified and analyzed, and the danger level of the disaster points was evaluated. The influence of geometric distortion in InSAR technology on the early identification of potential landslides in alpine-canyon terrain was also discussed. This case study can provide powerful data and technical support for local disaster prevention and mitigation and provide ideas and references for the early identification of the hidden dangers of landslides in mountain-valley areas.
