摘要
在论述区域地震地质概况的基础上，讨论了小兴安岭北坡地带至黑龙江畔的断裂活动、层状地貌特征、第四纪火山活动、黑龙江断裂的分段性及其特征，认为新构造活动的基本特征是地壳的差异性升降，地震活动的东强西弱与小兴安岭东西段新构造活动差异是一致的。
On the basis of regional seismogeological features analysis, the faults activities, layered geomorphologic features, Quternary valcanic activities, sectional characteristics of the Heilongjiang fault and so on are discussed. Determined that the basis features of new tectonic activities are the different crustal up and down movements in the area, strong in the east and weak in the west of earthquakes. The new tectonic activities of the east and west sections of the Xiaoxinganling ridge are almost the same.
