| 摘 要： | 根据断层面的最新错动方向，震源机制解和地壳形变等资料，研究了东南沿海地区的现代构造应力场，结果表明：本区构造应力场可大致划分为两个分区：长乐－诏安断裂带以东地区主压应力轴为近东西向；以西地区的主压应力轴近南北向。

| Abstract: | There were several different views on the recent tectonic stress field in the southeast China coastal seismic zone: (1) the principal compressive stress axis of tectonic stress field in the east of coastal was nearly in EW direction, and changed gradually in fan-shape from east to west, at last, in NS direction in Hainan Island1]; (2) that in the coastal area was in NWW-SEE direction2]3]; (3) that in the coastal area was nearly in NS direction4]. In last years, according to our study about the youngest displacement direction of fault Plane,crustal deformation and focal mechanism solution, the tectonic stress field of this area can be divided mainly into two parts: (1) the coastal area to the east of Changle-Zhaoan fault from Fuzhou to Haifeng, the principal compressive stress axis is nearly in EW direction; (2) in the wide area to the west of Changle-Zhaoan fault (include the west of Fujian, Guangdong, the south of Jiangxi, Hunan, Hainan and Guangxi etc ), that is nearly in NS direction. |
