Abstract:The stability of regional surface and architectural complexes is one of the key influencing factors for urban sustainable development. In order to master the development characteristics of surface deformation in main urban areas of J'inan city, 95 scenes and 48 scenes of Sentinel1 SAR data have been used to monitor the surface subsidence in Ji'nan from July 2016 to July 2019, and from June 2023 to March 2025 respectively. It is showed that the first stage of subsidence is mainly in the accumulation plain area in northwest Shandong province. It shows four large subsidence funnels. In the two monitoring results, the settlement of four subsidence areas has been greatly alleviated, among which the subsidence area of Sangzidian has changed from land subsidence to uplift. There is a small area of continuous subsidence in villages and traffic facilities on both sides of the Yellow River. Subsidence exists in some transportation hub facilities, some high-rise buildings and factories in the urban area. The research results can provide support for new basic surveying and mapping, help to improve the safety management and application service capabilities of urban geographic entities, and provide basic data and data support for accurate prevention and control of land subsidence and urban planning in Ji'nan city.
