摘　　要：中国中西部主要由中、新生代造山带与中、新生代盆地构成盆山格局 :秦岭造山带与南北两侧四川盆地与鄂尔多斯盆地 ;天山造山带与南北两侧塔里木盆地与准噶尔盆地 ;哀牢山造山带与东西两侧楚雄盆地与兰坪思茅盆地等 ,总体上构成盆山耦合。根据挤压造山带类型与前陆盆地类型 ,可以划分出 3种耦合类型 ,即 ( 1)碰撞造山带与周缘前陆盆地 ,( 2 )俯冲造山带与弧后前陆盆地及 ( 3)再生造山带与再生前陆盆地。因此前陆盆地是伴随着造山带的形成与演化而发育 ,造山带断滑系统直接控制前陆盆地结构、沉积层序及构造样式等 。Mesozoic-Cenozoic Basins and Mountain System constitute basin and range province in central\|western China. There are Qinling mountain system between Sichuan basin and Ordos basin, Tianshan mountain system between Tarim basin and Junggar basin, and Ailaoshan mountain system between Chuxiong and Lanping\|Simao basin, which constructed the coupling of basins and orogenic belts. According to the relationship between the mountain system and foreland basins the coupling of basins and orogenes could be classified into three types: (1) collisional orogenic belt and peripheral foreland basin, (2) subducted orogenic belt and retro\|arc foreland basin, and (3) reactivated orogene and reactivated foreland basin. Formation of foreland basin is response to orogeny. The architecture, sedimentary sequences, and structural styles of foreland basin are controlled by fault system of orogenic belt, which also control the order of petroleum accumulation in foreland basin.
