摘　　要：研究弱震活动性参数的时间进程和空间分布，这些参数是K=10与K=9地震数量之比（N10／N9）、震源深度以及震源机制确定的压应力轴方位角的变化。绘制出弱震活动性参数的空间分布图，识别可预报强震的弱震活动性参数的中期异常。得出强震前1～2年期间的强震孕育区位置。We study time course and spatial distribution of parameters of small earthquake activity, the parameters is ratio of earthquake number between K = 10 and K = 9, hypocenter depth and azimuthal chang of press stress decided by hypocenter mechanism. Protracted the spatial distribution of small earthquake activity parameters, identified medium - term anomalies of small earthquake activity parameters for strong earthquakes forecasting, obtained the gestation location of strong earthquake 1 -2 year before strong earthquakes.
