摘　　要：针对北京时间2023年12月18日,甘肃省临夏回族自治州积石山县发生了Ms6.2级地震,本次地震给当地造成了严重灾害损失。本研究主要使用欧空局2014年发射的Sentinel-1A卫星C波段雷达影像数据,采用合成孔径雷达干涉测量技术处理研究区范围内的同震形变场,通过不同升降轨数据的同震形变场的反演干涉结果进行对比,并结合其它数据反演结果进行验证,最后得出此次地震造成的地表形变变化,得到研究区内由于地震造成的地表抬升以及沉降结果。On December 18,2023,Beijing time,an Ms6.2 magnitude earthquake occurred in Jishishan County,Linxia Hui Autonomous Prefecture,Gansu Province,causing serious disaster losses to the local area.This study mainly used the C-band radar image data of Sentinel-1A satellite launched by the European Space Agency in 2014.Synthetic aperture radar interferometry technology was used to process the coseismic deformation field within the study area.The inversion interferometric results of the coseismic deformation field from different lifting orbit data were compared,and other data inversion results were combined to verify.Finally,the surface deformation changes caused by this earthquake were obtained,and the results of surface uplift and settlement caused by the earthquake in the study area were obtained.
