    Abstract:

    On the basis of analysis about the tectonic systems of the North-South seismic belt,the evolution of time-space dynamic pattern of seismicity is studied. The results show that the seismicity has the characteres as follow:① migration along the latitude direction,there are two kinds of migratory states in space,i.e. stepforward style and stepforward-return style;② the rapid respond in far distance;③ chain distribution of induced earthquakes,this feature indicates the coupling between strong quakes,and supports the trace for the position of future strong events;④ common repeat basis quality in space and time.The conclusions have certain practice values for judging the trend and realizing the correct prediction.
