摘　　要：通过野外地质调查和典型地震剖面构造解释,认为塔西南地区断裂构造发育,从山前部位至塔西南新生代前陆盆地,构造变形强度由强变弱,揭示了西昆仑造山带对塔西南地区的构造控制逐渐降低。因受厚层膏岩影响,致使研究区西北部、中部和东部地区构造变形存在差异,并且主要变形层位也有所差异。综合分析认为,塔西南地区存在三种主要盆山耦合类型,分别为叠瓦冲断式盆山耦合、双重构造式盆山耦合和堆垛构造式盆山耦合,分布于研究区的西部、中部和东部地区,这种差异主要与厚层膏岩滑脱层密切相关,同时也受到昆仑造山带和阿尔金造山带两种不同构造应力综合作用的制约。Through field geological survey and structural interpretation of typical seismic profiles,it is considered that fault structures are very common in Southwest Tarim Basin.From the Piedmont area to the Cenozoic foreland basin in Southwest Tarim Basin,the intensity of structural deformation changes from strong to weak,revealing that the structural control of the West Kunlun orogenic belt over Southwest Tarim Basin is gradually decreasing.Due to the influence of thick gypsum rock,there are differences in structural deformation in the northwest,middle and east of the study area,and the main deformation horizons are also different.Through comprehensive analysis,it is concluded that there are three main basin-mountain coupling types in Southwest Tarim Basin,namely,imbricate thrust coupling,duplex coupling and stacking coupling,which are distributed in the west,middle and east of the study area respectively.This difference is mainly closely related to the thick gypsum slip layer.At the same time,it is also restricted by the comprehensive action of two different tectonic stresses of Kunlun orogenic belt and Altun orogenic belt.
