| 摘 要： | 从第四纪地质研究的角度分析了珠江三角洲地区的地震危险性，认为北东，近东西和北西向三组断裂带把整个珠江三角洲断陷分割成７个次一级断块，并根据控制各次级断块的断裂第四纪活动性的强弱。

| Abstract: | This paper , analysised seismic risk characteristics in Pearl River Delta and considered that NE striking fault, nearly EW and NW striking fault zones jointly cut fault block of Pearl River Delta into 7 subblocks . Based on different activity of the fault zone since Quaternary and the Southeast China coast seismic belt seismicity law, the delta can be divided various seismic risk areas into 3 grade areas. |
