摘　　要：对豫鲁冀交界区域小震震源机制解进行了研究,分析应力场动态演化过程,进而探讨应力场异常与其他反映孕震规律的物理量(中等地震演化、波速比异常)的关系,在此基础上对本区域中强震的孕育情况进行综合判定。In this paper, we study the stress-field of minor earthquakes on the boundaries of Henan, Shandong and Hebei provinces and make analyses on its dynamic evolution. We further discuss the relation between anomaly stress field and other physical parameters （medium earthquake evolution and velocity ratio anomaly） which reflect earthquake-generating laws. On this basis, we comprehensively determine the medium-strong earthquake preparation situation of the region.
