摘　　要：利用ALOS-1(2007-2010)、Sentinel-1A(2017-2018)存档数据对山西交城-清徐地区的地面沉降进行监测。结合小基线和永久散射体技术优点,在增加时间采样密度的基础上利用二维线性回归分析得到研究区域的形变速率和时间序列。经同期GPS观测结果校核表明:交城-清徐地区持续发生地面沉降,但山区和平原区域形变的空间分布、量级不同,引起形变原因也不同。平原地带沉降空间分布受构造断裂控制,断裂带两侧呈现明显的差异性形变,且最大沉降速率为-200 mm/a,沉降的主要原因是地下水超采,但经治理后地面沉降灾害有所缓解,表现为沉降速率小于-30 mm/a。山区主要由于矿产资源的长期开采,沉降中心不断向南移动,最大形变速率为-462 mm/a。We use ALOS-1(2007-2010)and Sentinel-1 A(2017-2018)archive data to monitor the land subsidence in the Jiaocheng-Qingxu area of Shanxi.By combining the advantages of small baseline subset and persistent scatterer technology,the deformation rate and time series settlement of the study area are obtained by two-dimensional linear regression analysis based on increasing the time sampling density.When compared with the GPS observations in the same period,it shows that the ground subsidence continues in the Jiaocheng-Qingxu area,but the spatial distribution and magnitude of the observed deformation in the mountainous and plain areas are different,and the causes of deformation are also different.The maximum subsidence rate in the plain area is-200 mm/a respectively,which are believed to be mainly controlled by structural faults;there are obvious differential subsidences on both sides of the fault.Groundwater over-exploitation is a main reason for subsidence,but the land subsidence disaster has been alleviated after treatment.In the mountainous area,due to the long-term exploitation of mineral resources,the subsidence center has been moving southward,and the maximum subsidence rate is-462 mm/a.
