【摘要】 应用构造地貌的观点 ,把太原盆地及其边缘地貌分为 :外围断块抬升山地、抬升轻微的丘陵台地、山前堆积的洪积倾斜平原和沉降堆积的冲积平原 4种地貌单元。通过对边缘地貌形态、地震活动特点、水系演变规律以及古河道发育、新生代沉积厚度等特征分析 ,太原盆地新构造运动的特点为 :(1)盆地西部上升强烈、东部隆起较弱。 (2 )在整体上升过程中 ,构成两个隆起中心。盆地西部以石千峰为隆起中心 ,向南隆起幅度减小 ;盆地东部以绵山为隆起中心 ,向北隆起幅度减小。 (3)整个盆地新构造运动具有中心对称性。此外还论述了边缘地貌、新构造断裂及古河道的控水作用及其在水文地质方面的应用

【Abstract】 Based on the point of tectonic geomorphology,the geomorphology in and outside the Taiyuan Basin were divided into four geomorphologic units:periphery block rising mountain,slightly rising hill tableland,pluvial sedimentation plain,and alluvial sedimentation plain.By the analysis of edge geomorphol- ogy,landscape,earthquake characteristics,change of river system and developing feature of paleochannel, deposit depth of stratum in cenozoic,the neotectonic movement characteristics in Taiyuan Basin were as follows:rising intensely in western basin and slightly in eastern basin;on the whole rising course there were two rising centers;one was Shiqiangfeng in the northwest,the other is Mian Mountain in the south- east;the neotectonic movement in Taiyuan Basin showed a regularity of central symmetry.Moreover,the use of tectonic geomorphology and neotectonic movementin hydrology were discussed.
