摘　　要：对青岛及邻近地区的地震地质背景和地震活动情况进行了分析,并结合本区的小震综合机制解的特点,分析了P、T轴时序变化与邻区地震活动之间关系,发现中强地震的发生可导致研究区域内P、T轴方位的变化。P、T轴方位变化的时间较为同步,而P轴方位变化幅度更为明显。The seismogeological background and seismic activity in Qingdao and its adjacent area are analyzed. Combined the focal mechanism of small earthquakes in the region, the relation between time sequence variation of P and T axes and earthquake activities in adjacent area is studied. The results show that the occurrence of strong earthquakes can cause the variation of P and T axis direction. The variation of P and T axes is synchronous,but the magnitude of P axis change is more obvious.
