The composite fault plane solutions for earthquakes in the region of Sanxia, Macheng, Puqi and Danjiang are obtained respectively during the preiod from 1969 to 1981. The result shows that there is no uniform regional recent tectonic stress field in these areas. According to the orientation of the maximum compressive stress, the studied region can be divided approximately into four subregions. The characteristics of the stress field in the region are regarded as a particular phenomenon due to that it is located in the transition zone between Northern, Southern and Western China.
