摘要
本文以郑州市为研究区，利用2004年～2010年间26景Envisat-1雷达图像，采用永久散射体干涉技术（PS-InSAR）揭示了郑州市地面沉降的空间分布特征；根据InSAR解译结果开展地面沉降调查；并结合郑州市的地质构造、地下水以及城市建设等资料初步分析了郑州市地面沉降原因。
This paper took Zhengzhou as the research area to show the characteristics of the spatial extent of land subsidence in this city by using Permanent Scatterers Interferometric Synthetic Aperture Radar（PS-InSAR） technique and 26 Envisat-1 radar images which were captured during 2004-2010. According to the InSAR interpretation resuhs, reasons of land subsidence of Zhengzhou were preliminarily analyzed by using geological structure, groundwater and urban construction data.
