摘　　要：从太行山南段地貌面特征、分布、变形、变形时间四个方面对太行山南段隆升过程作了详细研究,认为:太行山南段新生代以来的隆升过程具间歇性,并估算了各阶段的隆升幅度,进而推测出太行山南段相对差异隆升成山的主要发生时期;对太行山南段和中段普遍发育的“U”形谷的形成时代进行了论证。最后得出:太行山南段构造地貌的形成是不同区块差异活动的结果,纵向上中部活动剧烈,南北两端次之,横向上具有东侧强西侧弱的特点。A detailed study was conducted on the uplift process of the southern section of the Taihang Mountains from four aspects:geomorphological features,distribution,deformation,and deformation time.It was found that the uplift process of the southern section of the Taihang Mountains since the Cenozoic era was intermittent,and the amplitude of each stage of uplift was estimated.Based on this,the main period of uplift in the southern section of the Taihang Mountains with relative differences was inferred;The formation era of the commonly developed"U"shaped valley in the southern and middle sections of the Taihang Mountains has been demonstrated.Finally,it can be concluded that the formation of the tectonic landforms in the southern section of the Taihang Mountains is the result of differential activities in different blocks.Vertically,the central part is highly active,followed by the north and south ends,and horizontally,it has the characteristics of strong on the east side and weak on the west side.
