摘　　要：海拉尔盆地以箕状断陷为主,且由东向西表现为东断西超、西断东超与东断西超交替出现,至西部以双断为主的变化规律。传递断层带可分为同向传递型、反向传递型及背向传递型 3 种类型。盆地基底构造格局对应力传递和局部应力场转化的控制作用以及传递带的存在是造成海拉尔盆地构造样式多样性的根本原因。The Hailaer basin is featured by a half graben. From east to west, the basin observes the following law: east-faulting and west-overlapping; west-faulting and east-overlapping and east-faulting and west-overlapping alternate in the east part, and to west double-faulting dominate. Three kinds of the transfer zones are recognized, they are:accordant, backward and reverse. The basic reasons causing the diversity in basin structural styles lies in its tectonic framework which controlled the stress delivery and local stress field transform and in the transfer zones exposed in the Hailaer basin.
