摘要: 为了掌握沈阳地区地面沉降状况，在充分搜集研究沈阳地区国家精密水准测量成果和不同时期1∶50000地形图成果的基础上，采用永久散射体干涉测量（PS-InSAR）技术，对沈阳地区地面沉降进行深入研究.结果表明，沈阳地区在1984年以前基本稳定，1984年以后地面沉降逐步发展，2007年以后地面沉降发展迅速，局部地区已经发展为地面沉降严重区.

Abstract: In order to recognize the status of land subsidence in Shenyang region, the permanent scatterer interferometric synthetic aperture radar(PS-InSAR) and other technologies are adopted on the basis of local precise leveling data and the 1:50000 topographic maps of the region in different periods. The result shows that, before 1984, Shenyang area is basically stable; since 1984, the land subsidence has gradually developed; then after 2007, the rapid development of land subsidence in local areas became more serious.
