摘　　要：青藏高原地质特征综合分析表明，高原的隆升主要是由于青藏板块仰冲到塔里木—中朝板块之上造成的。在重力的作用下，周缘地区形成一系列前陆型盆地，塔西南坳陷即是其中之一。它是第四纪以来青藏板块在向北仰冲推进过程中，主要由重力均衡和沉积负荷双重作用影响下快速沉降形成。Comprehensive analysis of geological characteristics of Qingzhang plateau indicated that its uplifting resulted from obduction of Qingzhang plate over Tarim-Zhongchao plate. Under the gravitational action, lots of foreland basin formed in peripheral areas. Among them, southwest depression of Tarim basin formed under the dual effects of gravity equilibrium and depositional load during the northward obduction in Quaternary period. Complex stratigraphy and structure systems in foredeep Kunlun are a result of successive raising of surface strata of underlying plate during Qingzhang plate movement and superposition of newlydeposited strata.
