| 摘 要： | 根据泥河湾保护区实地调查,黄土台地、黄土沟梁和河谷地貌是发育在“泥河湾层”及其覆地层上的主要地貌类型,其形态特征和形态测量反映了该区流水地貌的现代演化特征。伴随流水地质作用与地貌演化发生的水土流失、泥石流、崩塌和地面塌陷等地质灾害危及保护区的地层剖面。笔者认为该区域地质灾害是多种致灾因素造成的,其中的主导因素是气候、植被和人为因素,通过控制植被因素可以改变目前的地质环境状况。

| Abstract: | The landforms and geological calamity are the important studying subjects for the environmental protection in Nihewan reserve zone. The geological survey indicates that loess platform, loess ridge and gully, and river valley are the major landform types developed in " Nihewan Strata and its overlapped layers, their shape and measurement characteristics reflect the current evolutional characteristic of fluvial landform in this area. The geological calamities, such as soil erosion, mudflow, landslide and collapse, which caused by fluvial agent and geomorphic evolution, have endangered the reserved geological profile. The study indicates that the geological calamity in this area is caused by many factors, but the dominant factors are climate, vegetation and calamity activity. The current geological calamity can be controlled by the calibration of vegetation. |
