有关闽粤赣交界地区应力场和地震动力学的讨论

从地震地质学、GPS测量、地震活动性等多个角度对闽粤赣交界地区的区域应力场和地震动力学进行了讨论，结果表明：（1）闽粤赣交界地区应力场的主压应力方向为北西－南东向，主张应力方向为北东－南西向；（2）菲律宾海板块在台湾东海岸向北西西方向的挤压碰撞作用是台湾地区和闽粤赣交界地区强震孕育和发生的最直接最主要的动力来源。

Discussion on the Regional Stress Field and Earthquake Dynamics of the Border Area among Fujian, Guangdong and Jiangxi Provinces

The regional stress field and earthquake dynamics of the border area among Fujian, Guangdong and Jiangxi Provinces has been discussed from different aspects, such as the seismogeology, GPS survey and the seismic activity. The results show that:(1)In the stress field of the border area among Fujian, Guangdong and Jiangxi Provinces, the main compression stress direction is from northwest to southeast and the main tensile stress direction is from northeast to southwest;(2)The compression and collision to the east coast of Taiwan from Philippine block moving to the west-northwest is the most direct force cause of the strong earthquake to breeding and happening in Taiwan area and the border area among Fujian, Guangdong and Jiangxi Provinces.
