基于Sentinel-1数据的三峡库区木鱼包滑坡时空变形演化特性分析
Monitoring and Analyzing the Spatio-Temporal Deformation Characteristics of Muyubao Landslide in Three Gorges Reservoir Using Sentinel-1
摘要
Abstract
The fragile geological environment of the Three Gorges reservoir area,the effect of rainfall and reservoir water level lead to the wide distribution,large number and great harm of the Yangtze River main(branch)landslide.Landslide monitoring is one of the main measures for geological disaster reduction and prevention.Taking Muyubao landslide in the Three Gorges Reservoir area as the research object and using Sentinel-1 data as the data source,120 scene data in vicinity of Muyubao landslide from April 2017 to March 2021 were obtained.The spatio-temporal deformation evolution characteristics of Muyubao landslide were studied by using time-series InSAR analysis method.It was compared with the ground-based GNSS monitoring data and geological survey results.The results show that there are some differences between InSAR and GNSS monitoring data,but there is a good consistency in the evolution trend.Through the comparison between InSAR analysis results and field investigation,InSAR has a strong ability to monitor landslide boundary and large deformation in the process of landslide development and evolution.关键词
