摘　　要：台中—晋江横向构造带是一条重要的断裂带,控制了福建地区新生代地壳变形和现今地壳运动的南北差异。研究表明,受该断裂带控制,形成福建现代地壳运动南北分区,地壳活动南强北弱、南升北降的特点;历史中强地震基本分布在断裂以南的东部和邻近海域地区,形成南部地震集中区;1999—2006年环境剪应力值高值区集中分布在台中—晋江横向构造带以南,也反映了南强北弱、南北分区的特点。Taizhong-Jinjiang transverse structure belt is an important Faulted Zone, which controls the North-South differences of cenozoic diastrophism and current lithosphere movement of Fujian province. As studies shown, under the control of this Faulted Zone, the characteristics are formed that modem crustal movement of Fujian is districted by north and south, and crustal activities are weak and falling in the north but strong and rising in the south. Historically, high magnitude earthquakes primarily distribute in the east and adjacent sea area of southern Faulted Zone, so that a centralized earthquake area is formed in southern area. During 1999 to 2006, high environmental shear stress area is also centrally distributed to the south of Taizhong-Jinjiang transverse structure belt, which reflects the characteristics of strong in south, weak in north and the North-South division too.
