侵蚀现象促使流域地形发展,从这一观点出发,我们进行了关于表层型山崩发生处的流域地形构造考察。利用麦尔顿(M e l t o n)、霍顿(H o r t o n)、施赖夫(S c h r e v e)——高棹、杨(Y a n g)、斯特雷(S t r a h 1 e r)等的地形法则与作者以往的解析结果,把平衡状态下流域地形的全貌以地形要素与上述地形法则的关系为基础进行了归纳(表——1)。在本报告的阐述中,最重要的是下面两点。1、沟谷密度是决定流域地形诸要素中最重要的因素。2、对流域地形构造的基本单位即1级沟流域与流域地形的形成现象——表层型山地毁坏的规模而言,即使地形大小不同,但也存在着相似性。
From the viewpoint of erosion, the topography-type landslide occurred in the drainage area. Using topography rules such as M elton, Horton, S chreve-Gaudí, Y ang, S trah 1 er, Based on the analytic results, the overall topography of watershed under equilibrium condition is summarized based on the relationship between the topographic features and topographic features (Table 1). In the elaboration of this report, the most important thing is the following two points. 1, valley density is the most important factor in determining the terrain of the various elements of the basin. 2. For the formation of watershed topography, which is the basic unit of basin topography, that is, the formation of watershed topography - the scale of surface mountain destruction, there are similarities even though the topography is different in size.
