摘要
The offshore of China mainland includes the Bohai Sea,Yellow Sea and East China Sea. Based on the previous work, in combination with analyses of neotectonic movements of marine area and land and dynamic conditions, the authors attempt to make a further research on this region. The result shows that the recent tectonic stress field of this region is characterized by nearly horizontal compression, which is in NE direction in the north and gradually turns to NEE, EW, SEE and SE in the south, exhibiting a fan shape of diverging toward east. The intensity of tectonic stress is not uniform,relatively strong in the north and weak in the south.
