近年来，鄂尔多斯盆地南部环形影像特征逐渐引起人们的关注。这个独立于鄂尔多斯盆地的环形整体特殊形状的成因各有说法。在野外地质考察的基础上，通过分析对比和探究各种相关资料，发现：鄂尔多斯盆地南部环形区和秦祁海槽在各大构造运动中都有密切联系，二者处于同一应力场；鄂尔多斯盆地南部环形区的主要成因为其与秦祁海槽等周围块体之间的相互作用，包括挤压、碰撞、旋转和磨蚀；鄂尔多斯盆地南部环形区受到古生代到新生代多次构造运动的影响，其中燕山运动和喜马拉雅运动对其抬升及形状的形成起主要作用。

In recent years, ring structure in south Ordos basin has gradually aroused people's concern and it has many explanation for its formation. Based on the field geological study, this paper studies, analyses and compares a variety of data. We find that there is an intimate connection between Ordos southern annular region and Qinqi through in every major tectonic period and they are in the same stress field, the main cause of the ring structure in south Ordos basin is the interaction between it and the blocks around it, such as compression, collision, rotation and abrasion, and the southern Ordos basin ring is impacted by multi-phase tectonics and the greatest cause for its lift-ing and formation is Yanshan movement and Himalayan movement.
