摘要

使用永久散射体干涉测量(Persistent Scatterer Interferometric，PSI) 技术对福州市2018年1月至2023年6月的66景Sentinel-1A数据进行处理和分析，以获取地面形变监测结果，并通过交叉验证确保结果的精度。研究得到福州市整体形变速率在−44 ~18 mm/a之间，存在5个沉降较为明显的区域，其中4个靠近地铁线路，最大沉降位于长乐区峡漳路与福北路交界处。该地区的沉降是自然因素与人为因素共同作用的结果。从自然因素来看，沉降主要发生在第四纪沉积物地区；而人为因素则主要包括地铁建设、房屋建造与拆除等建设活动，以及仓库作业中货物装卸导致的地面荷载变化。该研究结果可以为福州市的城市规划建设和沉降灾害预防管理提供参考依据。

Abstract

In this research

66 Sentinel-1 images spanning from January 2018 to June 2023 were analyzed using Persistent Scatterer Interferometric (PSI) technology to map ground deformation in Fuzhou City. The accuracy of the results was demonstrated by cross-validation. The study reveals that the overall deformation rate in Fuzhou City ranges from −44~18 mm/a

with five distinct regions experiencing significant ground subsidence. Among these

four regions are located near subway lines

and the maximum subsidence occurs at the intersection of Xiazhang Road and Fubei Road in Changle District. The occurrence of subsidence in Fuzhou is the consequence of a complex interplay between natural and anthropogenic factors. In terms of natural factors

the subsidence is primarily distributed in areas with Quaternary sediments. The anthropogenic factors primarily include construction activities such as subway construction

building construction and demolition

as well as changes in ground loading due to warehouse operations such as cargo loading and unloading. The study results can provide a reference basis for urban construction and prevention management of subsidence disasters in Fuzhou.
