| 摘 要： | 基于D—InSAR技术，对西安市因过量抽取地下水导致的地表缓慢沉降做了深入的应用研究，利用已有的西安地区SAR图像做了差分干涉测量的试验分析。结果显示，D-InSAR技术已经能够很好的应用于城市地区厘米级地面沉降的监测。

| Abstract: | Based on D-InSAR, the traditional methods of monitoring Xi'an land subsidence caused by excessive water withdrawing were analyzed and estimated. Using the SAR images in Xi'an area, the authors made many differential interferometric measurement tests. The results showed that D-InSAR technology was still effective in monitoring the urban subsidence at centimeter level. |
