Abstract: Background of seism-dynamics controlled regularityies of the space-time distribution,seismogeny and pattern of regional seismicities. By the sample of space-time characteristic of seismicities in heishanxia gorge region on the yellow river, the text generalize the pattern of seism-dynamics to conjugation-sliding pattern in that area., and analysize, calculate the model by using 3d finite element method of nonlinear visco-elasticoplasticity, reveal the essence of active regularity.
