摘　　要：收集南海北部大量多道地震和钻井资料,编制了该区域首幅第四系厚度分布图。第四系等厚线总体呈NEE向,特别是珠江口外大陆架最明显,莺歌海、琼东南呈NW-EW-NE向弧形,珠江口大陆架南部存在次一级NW向等厚线。第四系等厚线分布形态明显受到断裂构造控制。After Collecting numerous multiple-channel seismic data and well data in the northern South China Sea, the paper draws the first distribution map of the quaternary thickness in this area. Basically, the direction of quaternary isopach is in NEE direction, especially for the continental shelf beyond the Pearl River. It shows NW-EW-NE direction for Yinggehai and Qiongdongnan. There is a NW direction isopach on the southern Pearl River Estuary. The distribution of the quaternary isopach is controlled by fault structures.
