摘　　要：本文基于ENVISAT ASAR数据,利用D-InSAR技术对天津地区2006年-2008年地面沉降进行计算,获得研究区地面沉降形变速率图,对西青区大寺镇沉降漏斗进行3D显示和剖面分析,并对实验中的误差做了估算分析。同水准监测数据比对,D-InSAR结果清楚地给出天津沉降区域空间分布,获得的沉降范围和位置同实际基本吻合,在数量级上同水准资料相一致。In this paper, ENVISAT ASAR images were processed by D-lnSAR technique to acquire ground subsidence distribution maps from 2006 to 2009 in Tianjin region. The D-InSAR results were used to analyze the ground subsidence displayed through profiles, contour lines and 3D views. Finally, numerous error sources in InSAR were analyzed roughly. Comparing with leveling data, D-InSAR could give the distribution of ground subsidence area clearly and reliably. Furthermore, the range and location of the ground subsidence with D-InSAR method were basically consistent with the actual range and location. The subsidence magnitude was consistent with the leveling data.
