| 摘 要： | 采用二轨差分的方法，对湿地区的SAR数据进行配准、滤波、去平地效应、相位解缠、差分处理等处理，最后得到垂直形变图，实现了地表形变的监测.通过计算，得到东郭苇厂、欢喜岭和西八千乡3个沉降中心.3处沉降量分别为-169、-78和-105 mm.沉降面积方面，东郭苇厂（A）沉降面积为5.14 km2，椭圆形沉降区的长轴方向为北东-南西向.欢喜岭（B）沉降区面积为0.42 km2，平面形态近似圆形.西八千乡（C）沉降区面积为5.28 km2，椭圆形沉降区长轴方向为北东-南西向.

| 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. |
