Based on the earthquake catalogue of the M_S8.0 Wenchuan earthquake, the temporal and spatial distributions of seismic sequence of 1 613 aftershocks with M_S≥3 from May 12th, 2008 to March 1st, 2010 were analyzed. The results showed that the aftershocks of the M_S8.0 Wenchuan Earthquake could be divided into seven stages, and the 18 days after principal shock should be the alert time for the strong aftershock. The b value of seismic sequence was 0.751, which confirmed the view “the greater magnitude, the higher b value”. The p value of seismic sequence was 1.117, which was considerable to global seismic attenuation rate. The distribution of aftershocks expanded along northeast direction of Longmen Mountain Fault, and was obviously zonal.
