Abstract：Land subsidence isa global geological and environmental problem，which seriouslythreatens the safety of surface and underground infrastructure construction.Inorder to find out the influencing factorsof land subsidence， the eastern section of the Tianshan Mountains was taken as the research object，and based on the sedimentation data of Persistent Scatterer Interferometric Synthetic Aperture Radar （PS -InSAR）and seven other influencing factors， the extreme random tree was used to analyze the influencing factors of land subsidence.Theresults showed that the overall subsidence in the studyarea in 2O22 was small，and there were sporadic subsidence areas in the area，with a maximum subsidence of 75mm . Elevation，topographic relief，slope，fault and precipitation had a great impact on subsidence，accounting for 93.3% of the importance，and construction and mining had no significant impact.
