AB  - Land subsidence can pose multiple threats to urban infrastructure, the natural environment, and socio-economic development; therefore, long-term monitoring is essential. In this study, 116 Sentinel-1 SAR images acquired between March 27, 2017 and July 19, 2025, together with precise orbit data, 30-m Shuttle Radar Topography Mission (SRTM) data, and GACOS zenith tropospheric delay products, were used to obtain surface deformation information in the Yellow River Basin of Lanzhou City through the SBAS-InSAR technique. The results indicate that significant land subsidence occurs in areas such as Yuanjiaying, Baidaoping, the surroundings of Xijinping, the northeastern part of Luojiatan, and the northwestern part of Baojiazui, while most regions within the study area exhibit no notable subsidence or uplift.
