| 摘 要： | 受地质构造、地层产状和岩性的共同影响,太行山中段山地地貌演化过程中,坡面发育模式产生了明显的分异:以华北准地台的吕梁期不整合面为界,基底层坡面发育以Davis模式为主,沟谷发育为垂直下切,地貌体垂直尺度小于水平尺度,地貌营力以流水为主,坡面侵蚀占主导地位,地表侵蚀强度低山区大于丘陵区,丘陵区大于台地区;盖层坡面发育以Penck模式为主,沟谷发育方式为横向侧切,地貌体垂直尺度远大于水平尺度,地貌营力重力占主导地位,侵蚀方式以崩塌为主。在晚第三纪以来的地貌演化过程中,陡崖平均后退速率为1.35mm/a。 |
| 关 键 词： | 太行山 地貌演化 坡面发育 陡崖后退速率 |

| Abstract: | Under the control of structure,strata behavior,and lithologic character,two slope development models exist in the geomorphic evolution process on middle Taihang Mountain in North China.Under the unconformity interface of double layer texture of North China Platform(Proterozoic),the slope development follows Davis Model:the vertical erosion is taken as dominant factor in valley development process,the vertical measurement is much shorter than the horizontal measurement for some geomorphic body such as valley... |
