摘　　要：讨论了南海北部陆缘断裂构造的格局及其活动性，提出南海北部陆缘地震带与邻区其它地震带有别的新观点，对该区各地震带的地震活动进行了探讨，分析了强震构造与活动断裂的关系。通过综合分析，将该区划分为强活动、中等活动和微弱活动三大区域。In this paper, the fault structures and their activities in North Continental Margin of South China Sea were discussed,and the earthquake activities of seismic belts in the area were studied. A new opinion was proposed that Seismic Belt of North Continental Margin of South China Sea deffers from other seismic belts in its adjacent areas.The relationship between strong earthquake structures and active faults was analysed. By comprehensive studies, the area is divided into three regions in regional stability.(that is, strong-active region,medium-active region, and lightly-active region.)
