摘　　要：盆地演化受地球演化节律所制约，节律由多层次构成。地球动力学旋回主要有３个级序：（１）超级大陆旋回，主要由羽柱构造的地幔对流动力学所控制，产生超级大陆的裂解和拼合，形成全球性同步隆升与沉降的克拉通盆地；（２）地槽旋回或造山旋回，主要由板块构造的岩石圈运动学所控制，按威尔逊旋回进展，发育各类盆地和造山带，形成“区域性”穿时开合与“非对称”互补；（３）褶皱幕或裂陷幕，主要由地体构造与拆层作用几何学所控制，产生盆地内各种构造样式和沉积样式，形成地方性的穿时递进变形，发育幕式变形和幕式沉积作用等。In terms of tectonic levels, geodynamic cycles fall into three main orders: (1) super continental cycles depend on plume tectonic processes that control cratonic basin generation and subsidence; (2) orogenic cycles depend on plate tectonic processes that control various proto basin generation and subsidence; (3) folding phase and rifting phase depend on terrane tectonic processes and delamination that control structural styles and depositional styles. These basins can be identified in different evolution stages in terms of plate movement, such as rift basins, continental margin basin, fore arc basins, back arc basins, remnant ocean basins, and foreland basins in Wilson cycle.
