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.
