| 摘 要： | 邵武－－河源地震带中段从1978年以来出现一次地震群体活动，属于该地震带第Ⅱ活动周期的第Ⅳ活动幕，现已转入这次活动幕的尾声，分析该区历史和现今地震活动特征及其应力状态，认为该区震源构造应力已整调、处于松驰状态。未来一段时间的地震活动将向起伏性减弱趋势发展。

| Abstract: | Since 1978, the activity of one earthquake swarm is appeared in the middle seismic zone of Shaowu Heyuan, which belongs to the fourth screen of the second active period and now it moves on to an end of this active screen. By analysing the characteristics and stress state of historical and present seismicities, it is thought that the source structural stress in this area is in the state of adjustment and flaccidity and the seismicities in the coming period of time will develop in the tendency of rising and falling and then go to the tendency of subsidence. |
