摘　　要：本文应用公元1600年以来新疆及边邻地区6级以上强震资料,详细讨论了1882年后本区经历的地震活跃期强震活动情况。指出了期中地震能量积累、大释放、剩余释放三阶段各自不同的特点;给出了划分活动期的统计模式;讨论了强震轮回的持续时间、关系、强度及存在的韵律现象;估算了本地震活跃期的大致结束时间;并对未来强震活动的发展趋势作了初步的分析。这些结果可为研究新疆地震活动性及地震形势的估计与预测问题提供线索。In this paper the activity of strong earthquakes during the seismically active period since 1882 in this region has been discussed in detail by using the data of strong earthquakes with magnitude of 6 or larger in Xinjiang region and its neighboring area since 1600. The different features for three stages of accumulation, release and residual release of seismic energy have been also pointed out. We gave a statistical model of dividing the active periods and discussed the duration, relation and intensity of the strong earthquake transmigration as well as the phenomenon of rhymic scheme. The end time of the seismically active period has been approximately evaluated. Finally, we analyzed roughly the developing trend of strong activity in future.These results will provide the clue to researching seismicity in Xinjiang region and evaluating the seismic situation.
