摘　　要：综述了许多学者对逆牵引背斜构造特征和形成机理的讨论。根据近年来对于渤海湾新近纪—第四纪盆地的研究,提出了一种新的解释,即逆牵引构造和伴生的简单或复杂y字形正断层组合是由于区域伸展作用下不同运动方式和差异位移产生的,并强调指出,逆牵引背斜构造与走滑作用产生的负花状构造在构造特征和成因上是不同的,不要把这两者混为一类构造。The structural characteristics and origin of reverse drag anticlines discussed by many authors are re- viewed in this paper. Based on recent research on Neogene and Quaternary in Bohai Bay Basin, author proposes a new explanation： the reverse drag anticlines and associated single or complicated y-shaped normal faults resul- ted from the modes of movement and differential displacement by regional extension, and it is emphasized that the characteristics and origin of reverse drag anticlines are different from negative flower structures and the former should not be confused with the latter.
