摘要
对长江中下游南黄海地震带地震活跃期、幕划分及其发展趋势进行了研究，对江苏及其邻区今后几年的地震大形势及重点危险区进行了判定。分析认为，长南带从１９７１年以来进入第二活跃期的第３幕，该幕地震活动将持续到２０１０年前后，最高活动水平为６．５级左右。今后几年江苏东部至南黄海海域发生５～６级或６级以上地震的可能性较大。
The seismicity period, episode division and seismic tendency have been researched. It is concluded that the seismicity come into third episode of second seismicity period, started from 1971, and will continue to about 2010, its highest active level is some M S 6.5. It is very possible that the earthquake of M S 5～6 or more than M S 6.0 will occur from east Jiangsu to south Yellow sea in future years. Finally, the seismic tendency and key hazard regions of Jiangsu and adjacent area in future years have been identified.
