摘　　要：以辽宁义县中东部区域为例,选2017—2018年间18景Sentinel1数据,采用短基线差分干涉测量技术(SBAS-InSAR)获取了该地区的形变时间序列和平均沉降速率。结果显示义县存在不均匀的沉降,最大平均沉降速率为98 mm/a。结合野外实地调查成果,验证了SBAS-InSAR技术的可靠性,并分析了地表沉降的主要原因是矿石的开采。Taking the central and eastern region of Yixian,Liaoning Province as an example,the data of 18 landscape Sentinel-1 from 2017 to 2018 were selected,and the deformation time series and average subsidence rate of the region were obtained by using the short-baseline differential interferometry(SBAS-InSAR).The results showed that there was uneven subsidence in Yixian,and the maximum average subsidence rate was 98 mm/yr.Combined with the field investigation results,the reliability of SBAS-InSAR technology is verified,and the analyzing results show that main reason of surface subsidence is ore mining.
