摘　　要：文章探讨了塔里木盆地北缘和南天山造山带的盆-山耦合和构造转换过程。塔里木盆地属于典型的叠合盆地,经历了多期构造演化。研究表明,在地史时期中,塔里木盆地北缘和相邻南天山造山带经历了多期和复杂的盆山耦合和盆山转换过程,形成多种类型盆山耦合和转换方式。(1)按时间域可划分为:早古生代陆内裂陷盆地-早期伸展造山-晚期挤压造山耦合,晚古生代陆内裂陷盆地-弧后造山-晚期碰撞造山耦合,中生代陆内前陆盆地-挤压造山耦合,古近纪前陆盆地-挤压造山耦合,新近纪—第四纪再旋回前陆盆地-挤压造山耦合;(2)按深度域可划分为:深部地幔俯冲型盆-山耦合,地壳分层滑脱拆离型盆-山耦合,基底滑脱拆离型盆-山耦合,古生代伸展和逆冲推覆型盆-山耦合,中—新生代逆冲推覆型盆-山耦合;(3)按运动学和动力学可划分为:逆冲推覆型盆-山耦合和接触关系、重力滑脱型盆-山耦合和接触关系、走滑转换型盆山耦合和接触关系、深部岩浆上涌焊接型盆-山耦合和接触关系、鳄鱼嘴型盆-山耦合和接触关系。The purpose of this paper is to analyze the basin-mountain coupling and the process of tectonic transition between Northern Tarim Basin and Southern Tianshan Orogenic Belt.The typical superimposed Tarim Basin experienced poly-cycle tectonic evolution.It is indicated that poly-phase and complex basin-mountain coupling and basin-mountain transition existed in the Northern Tarim Basin and the adjacent Southern Tianshan Orogenic Belt.（1）Basin-mountain coupling and tectonic transition according to the geological time realm： coupling of the intra-continental rifting basin-early phase extensional orogeny-later stage compressional orogeny during the period of the early-Paleozoic,coupling of the intra-continental rifting basin-retro-arc orogeny-later stage collisional orogeny during the period of the Later-Paleozoic,coupling of the intra-continental foreland basin-compressional orogeny during the Mesozoic,coupling of the foreland basin-compressional orogeny in the Eogene,and coupling of the re-cycled foreland basin-compressional orogeny in the Neogene-Quaternary.（2）Basin-mountain coupling based on the depth realm： basin-mountain coupling of the deep mantle under-thrusting,coupling of the multi-level detachment in the crust,coupling of the detachment in the basement,coupling of extension and thrust-nappe in the Paleozoic,and coupling of thrust-nappe in the Meso-Cenozoic.（3）Basin-mountain coupling according to the kinematics and geodynamics： thrust-nappe-type basin-mountain coupling,gravitational-detachment-type basin-mountain coupling,wrench-transfer-type basin-mountain coupling,magma-weld-type basin-mountain coupling,and crocodile-mouth-type basin-mountain coupling.
