摘　　要：本文从华东地区的特定构造体系入手，定性和定量地分析了华东地区ＭＳ≥５５地震的活动水平和时空分布特征；从图像演变角度入手，分析了中强震活动的规律。The special characteristics of tectonic system in East China have been described .The seismic activities and temporal spatial distribution of earthquakes with M S≥5.5 in East China have been analyzed quantitatively and qualitatively. According to the evolution of seismicity patterns,the regularity of moderately s trong earthquake activity has been analyzed,and the judgement for the tendency o f the forthcoming earthquake in East China is given.
