摘　　要：在对1987～1995年度地震预测意见作回顾性检验的基础上，研究了甘肃省及邻区6～7级地震前兆异常的共性特征及地区性特征。研究结果表明，前兆异常时空分布不仅与强震大小有关，还与前兆台网布局和后续强震的相对位置有关。By reviewing the earthquake prediction opinion among 1987~ 1995, the commonand regional features of earthquakes with Ms 6~ 7 in Gansu province and its neigh-bouring region are studied. The results indicate that the spatial and temporal distributionof precursory anomaly related to not only the magnitude of the strong earthquakes, butalso the distribution of precursory networks and the relative position of the followedevents.
