摘要
2017-08-08九寨沟Ms7.0地震给当地人民和生态环境带来了巨大的损失,灾后重建成为当地的一项重要任务。文中选取九寨沟地震区震后2017-08-14—2018-07-01的Sentinel-1A数据作为SAR影像,采用小基线集技术监测该地区时间序列形变。研究结果基本查明该区域的整体形变情况,并从中找到下沉较为明显和形变规律异常的区域,为震区灾后重建、地表形变监测和地质灾害预防提供理论和数据支持。
On August 8,2017,Ms7.0 Jiuzhaigou Earthquake caused huge losses to the ecological environment and the local people.Post-disaster reconstruction has also become an important task in the local area.In this study,Sentinel-1A data from August 14,2017 to July 1,2018 was selected as the SAR image,and the time series deformation was monitored by Small Baseline Subset technique.The result of this study basically identifies the overall deformation of the area,and finds the areas with obvious subsidence or abnormal deformation,providing a theoretical and data support for reconstruction,surface deformation monitoring and geological disaster prevention in the earthquake area.
