摘　　要：利用闽台地区GPS水平速度场数据,构建出闽台地区连续地壳运动速度场与应变场,进而揭示了闽台地区整体的地壳运动与变形特征。结果显示:闽台地区地壳运动由台湾地区向福建地区减弱,台湾海峡地区地壳运动速度场和最大剪应变场强于福建地区,但弱于中国台湾地区。文章首次展示了台湾海峡地区的这些地壳运动与变形特征,为今后该区域强震预测和地球动力学问题的研究提供了参考。We constructed crust continuous velocity field and strain field in Fujian-Taiwan Region using GPS horizontal velocity field data,and the entire characteristics of crust movement and deformation in Fujian-Taiwan Region was revealed.The result show that the crustal movement attenuate from Taiwan Region to Fujian area.The velocity field and maximum shear strain field of crustal movement in Taiwan Strait are stronger than those in Fujian,but weaker than those in Taiwan,China.This paper showsfor the first time the characteristics of these crustal movements and deformation in the Taiwan Strait,thus providinga reference for the study of strong earthquake prediction and geodynamics in this region in the future.
