通过D-InSAR技术获取了临汾水准两次巨幅形变异常期间的区域垂直形变场，结果显示：2009年2月20日至2009年10月23日，临汾水准所在的龙祠区域无明显变形，临汾市区南部出现的10～20mm的下沉区域为周边密集分布的多个电厂大量开采地下水所致；2010年1月1日至2010年3月12日，大部分区域变形量基本为零，在临汾盆地内部存在一些小的、空间上不连续分布的沉降区域。幅度约为10mm左右，此类型的沉降区域多与城市发展过程中大规模抽取地下水有关。基于InSAR的结果，表明临汾水准BN，测点的巨幅形变异常在InSAR形变图上无法显示，属于局部地区小范围的变形。

The ground vertical deformation field of Linfen area during the two times of huge deformation anomaly is figured out by D-InSAR technique. The result shows that from Feb. 20th, 2009 to Oct. 23rd, 2009,the Longei area where Linfen level locates had no significant deformation. A 10-20mm subsidence appeared in the south of Linfen city may be related with groundwater over-exploited by lots of power plants around. From Jan. 1st, 2010 to Mar. 12th, 2010, most of the region had almost no deformation and only some places had small-scale, discontinuous subsidence about 10mm within Linfen basin, which may be related with the over-exploitation of groundwater with the urban development. The huge abnormal changes of BM3 point of Linfen level couldn＇ t be displayed on the InSAR deformation map, which means that is such a change is only a localized deformation.
