摘　　要：以东海陆架盆地南部为重点研究对象,基于区域地震反射资料,结合盆地的结构特征,分析、总结了其构造样式特征。结果表明:根据构造样式形成的动力学机制,可以将东海陆架盆地南部划分为伸展型构造样式、挤压型构造样式和复合型构造样式3类;伸展型构造样式可继续分为半地堑(箕状断陷)构造组合、复式地堑式构造组合、多米诺式断裂构造组合、掀斜断块和火成岩构造;挤压型构造样式分为挤压背斜、断背斜和叠瓦式断裂组合;复合型构造样式分为正反转构造和负花状构造。Based on regional seismic data,we studied in this paper the structural characteristics of the southern East China Sea Shelf Basin. Our results show： （1） There are three structural styles, namely extensional, compressional, and complex structures, in the study area according to their dynamic mechanism. （2）The extensional structural style can be further subdivided into the half graben, composite graben, domino faulted graben, tilting block and magmatic structures. The compressional structural style can be subdivided into compressional anticline, faulted anticline and imbricated faults. The complex structural styles can be subdivide into positive inversion tectonics and negative flower structures.
