摘　　要：盆山耦合分析应该将地球动力学环境和板块运动学序列结合起来 ,根据地球动力学环境所提出的 :伸展构造体系、挤压构造体系、走滑构造体系和克拉通构造体系进行定性与定量分析 ;依照板块运动学序列所划分的主要旋回 :裂解阶段、俯冲阶段、碰撞阶段和后造山阶段进行定位与定时分析 .伸展构造体系在离散期为陆内裂陷盆地及伸展造山带 ;在聚合期为弧后裂陷盆地及张性岩浆弧造山带 ;在后造山期为后继裂陷盆地及晚期伸展造山带 .挤压构造体系在俯冲期为弧后前陆盆地及俯冲造山带 ;在碰撞期为周缘前陆盆地及碰撞造山带 ;在再活动期为再生前陆盆地及再生造山带 .走滑构造体系在伸展期为走滑拉分盆地及剪张山岭 ;在挤压期为走滑挠曲盆地及剪压造山带 .克拉通构造体系在裂解期为克拉通内部盆地 ;在拼合期为克拉通边缘盆地 .The concept of the coupling of basin and mountain system is to well organize and combine the former isolated basin analysis and mountain research together through the geodynamic scenario and the plate tectonic setting analysis. Geodynamic scenario, including extensional tectonic system, contractional tectonic system, transcurrent tectonic system, and cratonic system, can lead geologists to get the right ideas of qualitative and quantitative analysis in their research. At the same time, plate tectonic setting, including rifting stage, subduction stages, collision stage, and post-orogenic stage, can provide them with the knowledge of the geological events in space and time. According to the extensional regime, there are continental rift basins and extending orogen in divergent stage, back-arc basins and magmatic orogen in converging stage, and successor rift basins and late-extensional orogen in post-orogenic stage. While in the contractional regime, there are retro-arc foreland basins and subduction orogenic belts in subduction stage, peripheral foreland basins and collisional orogenic belts in collision stage, and reactivated foreland basins and recycling orogenic belt in reactivated stage. In transcurrent regime, there are transtensional basins and range in transtensional stage, and transpressional basin and mountain zones in transpressional stage. In cratonic regime, there are intracratonic basins in divergent stage, and craton-margin basins in converging stage.
