摘　　要：利用山东数字地震台网的地震波形记录,选取2007年以来台网记录清晰的M_L≥2.0数字地震波形资料,计算每次地震的环境剪应力值τ_0和矩震级M_W,并分析其相关关系;结合山东地区地质构造和地震活动性特点,对胶东半岛及北部海域、南黄海北部地区、沂沭带地区、冀鲁豫交界地区应力场分布和时空变化进行细致分析,并探讨其区域特征及与地震活动性的关系。Using the broad-band digital data,selected of L≥ 2 .0 waveform data recorded by Shan-dong digital seismic network since 2007 ,we calculated the stress values and moment magni-tude Wfor each earthquake and analyzed the correlation between them.Combinning Shan-dong geological structure and characteristics of seismic activity,wq analyzed stress field dis-tribution and its temporal and spatial variation in Jiaodong Peninsula and the northern wa-ters,the northern region of the South Yellow Sea,Yishu belt regions,Shandong and Henan border region.We also explored the regional characteristics of stress field and the relation-ship with seismic activity.
