| 摘 要： | 根据福建GPS监测网3期(1997，1999，2001)观测资料的计算结果，分析了福建沿海地区的现今地形变特征。(1)福建地区有两个剪应变相对集中区，北部是湾口、闽清一带；南部是泉州、厦门一带。这两个区的剪应变随时间变化有加强的趋势。(2)南部剪应变集中区基本处于压应变环境，并且主要断裂两侧存在相对较高的剪应变集中区，值得关注。

| Abstract: | In the light of the computed results of measurement data of GPS observation network in 3 periods (1997, 1999, 2001)we have analyzed the current deformation characteristics along the coast of Fujian as follows. (1) There are two relative concentration areas of shear strain in Fujian:the northern one is Wankou-Minqing and the southern one is Quanzhou-Xiamen.In addition,the shear strains in the two areas show a increasing trend with time. (2)the southern area of shear strain concentration is basically in a compressive strain condition and there exists relative high shear strain concentration area on the two sides of the principal fault. |
