【摘要】 根据福建GPS监测网 3期 (1997,1999,2 0 0 1)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。更多还原

【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.更多还原
