Abstract：The two-pass D-InSAR method is adopted for the registration, filtering, flat-earth phase removal, phase unwrapping, differential processing of the SAR data in Panjin wetland, to obtain the vertical deformation map and realize the land subsidence monitoring. By calculation, the subsidence amounts of three subsidence centers, namely Dongguoweichang, Huanxiling and Xibaqianxiang, are -169, -78 and -105 mm, respectively. In respect of subsidence areas, Dongguoweichang (A) is 5.14 km2, in oval settlement area with NE-SW trending long axis; Huanxiling (B) is 0.42 km2, nearly circular plane shape; Xibaqianxiang (C) is 5.28 km2, in oval settlement area with NE-SW trending long axis.
