摘　　要：渤海及邻近地区是我国东部地震较活跃的地区之一，历史上曾发生过多次强震，现今小震活动也较活跃。因该区域主要处在郯庐断裂带和燕渤断裂带上，且这两大断裂带在渤海内交汇，故造成该区域地震活动频发。本文主要是分析了该地区近期地震活动的空间、时间和强度3个方面，总结了地震活动的空间、时间和强度的特征。为本地区地震灾害的防御，减灾等方面工作提供依据。The Bohai Sea and its surrounding area is one of the regions of main earthquake activity in eastern china. Not only there were a lot of strong earthquakes in the history, but also many small earthquakes happened in recent years. In this region, Tanlu and Yanbo fracture zones rendezvous in Bohai Sea and so many seismic activities happen. In this paper, the recent earthquake activity is analyzed in the three aspects, space, time and strength, in order to sum up the special, temporal and intensive features of seismic activity. Then it can provide measures for the earthquake disaster prevention and mitigation in this region.
