摘　　要：本文基于2022年12月至2025年1月的26景Sentinel-1A数据,采用PS-InSAR技术监测钟祥市主城区地面形变。研究发现:城区不同区域地面形变特征差异显著,中心区及南部存在轻微抬升,最大累积抬升量达16 mm;北部局部区域出现明显沉降,最大沉降速率为-6.8 mm/yr;形变主控因素包括地质构造活动、地表水补给效应及城市建设活动。研究揭示了钟祥市地面形变时空分布规律,为城市安全规划和地质灾害防控提供了重要参考依据。This article,based on 26 Sentinel-1A datasets from December 2022 to January 2025,uses PS-InSAR technology to monitor ground deformation in the main urban area of Zhongxiang City.The study finds significant differences in ground deformation characteristics across different urban areas:the central and southern regions exhibit slight uplift,with a maximum cumulative uplift of 16 mm;localized areas in the north show obvious subsidence,with a maximum subsidence rate of-6.8 mm/yr;The main controlling factors of deformation include geological structure activity,surface water recharge effects,and urbanization construction.The research results can provide a scientific basis for urban safety planning and geological disaster prevention in Zhongxiang City.
