| 摘 要： | Based on the hypothesis of the active tectonic blocks on the Chinese continent and its adjacent regions (both the method of the DDA on a spherical surface and the GPS survey results observed from 1991 to 2001 are used), the movements and deformations of each active tectonicblock are calculated. The calculation results show that although the movements and deformations of active tectonic-blocks in the eastern region and in the western region of China are different, active tectonic blocks in the same active tectonic block region are coherent.Then, the relative velocities of the active tectonic-blocks‘ boundary zones are calculated, and the relationship between current crustal motion and strong seismic activities is discussed. Earthquakes (Ms≥7.0) on the Chinese continent since 1988 all occurred on boundary zones of active tectonic blocks with high slipping speed.
