摘　　要：2006~2015年天津地区GPS连续观测站形变和应变计算结果显示,天津地区形变场和应变率场变化复杂,存在南北分带和东西分带特征。天津地区形变场和应变场主要受控于唐山-磁县地震构造带和张家口-渤海地震构造带等多组活动断裂的切割作用。Based on the deformation-strain calculation of GPS continuous observation station in Tianjin area, the results show that the deformation field and strain rate field are complex, with east-west zon- ing as well as south-north zoning. It is considered that the Tianjin area is located in different tectonic intersection area, which is affected by the Tangshan-Cixian seismic-tectonic zone, the Zhangjiakou-Bo- hal seismic-tectonic zone, and other active faults.
