城市地面沉降问题日益突出,传统的水准等地面沉降监测手段成本高、效率低,在地面沉降监测技术创新上,最近发展的永久散射体雷达干涉技术(PS-InSAR)具有低成本、大面积和高精度的优势。本文利用2003-08—2010-09年间的39景覆盖太原市的Envisat ASAR影像,基于StaMPS PS-InSAR方法获得该时期太原市的地面沉降速率图,为相关部门采取有效措施遏制太原南部地区地面沉降提供了科学依据。 The problem of urban land subsidence has become increasingly prominent. The conventional land subsidence monitoring methods such as traditional leveling are costly and inefficient. Recently, PS-InSAR has the advantages of low cost, large area and High-precision advantage. In this paper, the Envisat ASAR image of Taiyuan was covered by 39 scenes from 2003-08 to 2010-09, the land subsidence rate map of Taiyuan was obtained based on StaMPS PS-InSAR method, and the relevant departments were taken effective measures to restrain the land subsidence in the southern part of Taiyuan Provide a scientific basis.
