| 摘 要： | 文章在阐述黄河上游龙羊峡-刘家峡河段内滑坡类型及分布的基础上,分析了滑坡发育与黄河形成演化历史的关联性。认为距今12.5万a前后的共和运动使得黄河溯源侵蚀加剧,水资源的重新分配,导致黄河切蚀能力加强,并于距今1.8-2.9万a达到高潮。因此,构造抬升致使黄河水流快速下切,是造就区内特大滑坡发生的根本原因。

| Abstract: | Based on the landslide's types and distributions from Longyang Gorge to Liujia Gorge at the upper reach of the Yellow River,this paper analyzed the relationship between the development of landslide and the evolution history of the Yellow River.The results show that Gonghe movement about 125 kaB.P.made the headward erosion of the Yellow River stronger,meanwhile the redistribution of water resource made it down erosion power stronger.And the erosion power reached maximum about 18kAB.P.to 19kaB.P.So,ultimate reason of oversize landslide in this ara is the quick down erosion of the Yellow River led by structural raising. |
