Slow, long-term ground deformations in the Dąbrowa Basin (southern Poland) were identified based on ERS-1 , ERS-2 and ENVISAT Synthetic Aperture Radar (SAR) images that were processed by means of Permanent Scatterer SAR Interferometry (PSInSAR). The Dąbrowa Basin is a region where two major factors can affect surface stability: intensive coal exploitation and neotectonic processes. In this study, in order to clarify the origin of surface deformations, the authors propose applying a newly developed algorithm of spatio-temporal PSInSAR data analysis. This analysis revealed that subsidence is a characteristic feature of the Dąbrowa Basin. A significant correlation exists between slow, long-term ground deformations and the location of the main tectonic structure of this region. The proposed spatiotemporal analysis of the PSInSAR data additionally showed some degree of correlation between mining activity and the studied deformations. This interconnection is a significant achievement of this study since the deformation values determined by means of PSInSAR were identified in earlier works solely on the basis of Dąbrowa Basin neotectonics.

基于 PSInSAR 分析的 Dąbrowa 盆地（波兰）地表变形模式

Dąbrowa 盆地（波兰南部）的缓慢、长期地面变形是基于 ERS-1、ERS-2 和 ENVISAT 合成孔径雷达 (SAR) 图像确定的，这些图像通过永久散射 SAR 干涉测量 (PSInSAR) 处理。Dąbrowa 盆地是一个影响地表稳定性的主要因素有两个：密集的煤炭开采和新构造过程。在这项研究中，为了阐明表面变形的起源，作者建议应用一种新开发的时空 PSInSAR 数据分析算法。该分析表明，沉降是 Dąbrowa 盆地的一个特征。缓慢、长期的地面变形与该地区主要构造结构的位置之间存在显着的相关性。拟议的 PSInSAR 数据时空分析还显示了采矿活动与研究变形之间的某种程度的相关性。这种相互联系是本研究的一项重大成就，因为在早期工作中仅根据 Dąbrowa 盆地新构造确定了通过 PSInSAR 确定的变形值。正常 0 21 false false false PL X-NONE X-NONE /* 样式定义 */ table.MsoNormalTable {mso-style-name:Standardowy; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow：是；mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; 行高：115%；mso-分页：寡妇孤儿；字体大小：11.0pt; 字体系列：“Calibri” ，“无衬线字体”; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-fareast-language:EN-US;}
