摘要:地面沉降及其引发的次生灾害已成为我国城市主要地质灾害之一，对地面沉降进行大范围、持续、动态监测是城市智慧建设与管理、维护城市可持续发展的基础，也是预防、预警城市地质灾害发生的有力保障。PSInSAR技术克服了常规DInSAR技术的时间、空间失相干等影响，采用二维线性（或非线性）模型、时空滤波方法去除长时间观测序列干涉图中的相位噪声，对高相干点的差分干涉相位回归分析，即可获取大面积地表形变动态演化信息。本文以豫北安阳地区为实验区，对2008年3月至2009年12月近两年时间的11期ENVISAT/ASAR SAR 数据进行PSInSAR处理，获得安阳地区地表沉降速率场。研究发现，安阳城区及西郊都存在明显的地面沉降，城区有龙安、殷都、北关、文峰4个区因超采地下水导致地面沉降，其中最大沉降位于文峰区，沉降速率达-38 mm/a，而西郊水冶镇因矿区地下开采而缓慢下陷形成沉降场，其最大沉降速率达-32 mm/a。

Abstract:Land subsidence and its related hazards have become one of the major geological disasters in most cities of China. Long-term and dynamic monitoring of land subsidence is crucial for urban wisdom construction， management， and maintenance of urban sustainable development. It is also an important guarantee for preventing and early warning of the potential occurrence of urban geological disasters. PSInSAR is a powerful tool to obtain small-magnitude deformation in experimental area by using two-dimensional linear（ or nonlinear） phase regression analysis for differential interferometric phase at persistent scatters. PSInSAR has ability to correct mutiple phase error due to phase decorrelations in temporal and spatial domain and various atmospheric phase delay in multiple interferograms. PSInSAR method and phase composition were applied， and Anyang City in Henan Province was taken as experimental area. Eleven SAR images acquired by ENVISAT/ASAR from March 2008 to December 2009 were used to derive subsidence in Anyang City. Significant subsidence signals in Anyang urban district and suburban area are obtained. Subsidence fields in Anyang urban district due to over-exploitation of groundwater were Longan， Yindou， Beiguan and Wenfeng districts. The largest subsidence rate was  - 38 mm/a in Wenfeng district. Subsidence fields in Anyang suburban district due to mining was Shuiye town. The largest subsidence rate was - 32 mm/a in Shuiye town.
