【摘要】 由于黑山峡地区极易发生地质灾害，选用该区域2020年的三期Sentinel-1卫星数据，利用D-InSAR技术进行了处理。通过比较两期形变，由此得到了黑山峡地区在三期数据的1-2、2-3时间间隔内的地表平均形变量分别为[-106.685,175.724]和[-81.773,112.659],2个时段数据的结果比较表明：此区域的沉降分布通常是一致的，并且范围有显著的收缩趋势。更多还原

【Abstract】 Due to the high vulnerability to geological hazards in the Heishan Gorge area, the three phases of Sentinel-1 satellite data for 2020 were selected for processing using D-InSAR technology. By comparing the two periods of deformation, the resulting mean surface deformation variables for the Black Hills Gorge area during the 1-2 and 2-3 time intervals of the three periods of data were[-106.685, 175.724] and [-81.773, 112.659], respectively. Comparison of the results of the two time periods of data indicates that the distribution of subsidence in this area is generally consistent and there is a significant trend of shrinkage in extent.更多还原
