摘　　要：针对新汶矿区,采用SBAS-StaMPS方法对2016~2020年48景Sentinel-1A影像进行时序分析,反演了4年的地表形变过程,提取了8个采煤区地表时序沉降量,最大沉降量达180 mm,最大沉降速率为44.49 mm/a,沉降区中心表现出匀速型、阶梯型和加速型三种趋势。结果表明SBASStaMPS方法能够有效应用于多植被覆盖的采矿沉陷区识别与监测,可作为矿区地表形变监测分析的有效手段。Time series analysis on 48 scenes of Sentinel-1 A images was analyzed by the SBAS-StaMPS method from 2016 to 2020 in Xinwen mining area.Surface deformation process was inverted for 4 years.The time series of surface subsidence was obtained in 8 coal mining areas.Maximum settlement was 180 mm,and the maximum deformation rate was 44.49 mm and acceleration.Results showed that the SBAS-StaMPS method could be effectively applied to the identification and monitoring of mining subsidence areas with a large amount of vegetation cover,providing the effective method for monitoring and analysis of surface deformation in mining areas.
