| 摘 要： | 土林地貌是指在干旱-半干旱地区, 由半松散-半固结的碎屑沉积物经过流水剥蚀、堆积形成的林柱状、墙状及沟谷等一系列地貌的统称。以往对土林的研究不够系统和全面, 甚至将其归为黄土地貌。本文通过统计土林地貌在全世界范围内的分布, 分析研究了土林地貌的分布规律、物质组成和形成原因, 认为土林地貌具有自身独特的形成规律和形态特征。土林地貌从物质组成和形态上属于沉积岩地貌; 从成因上划分应属于剥蚀地貌中的流水剥蚀地貌, 并伴随有流水堆积地貌的特征, 其中剥蚀地貌进一步划分为沟谷地貌、林柱地貌和潜蚀地貌。

| Abstract: | Earth forest landform refers to a series of landforms, including forest column shape, wall shape and gully, which are formed in arid to semi-arid areas through erosion and accumulation of semi-loose to semi-consolidated clastic sediments by running water. Previous studies of this landform were not systematic and comprehensive enough, and even classified it as loess landform. In this paper, the distribution law, material composition and formation reason of earth forest landform were analyzed and studied by counting the distribution of earth forest landform in the world. Based on the study, it is found that earth forest landforms have their own unique formation rules and morphological characteristics. The earth forest landform belongs to sedimentary rock landform from material composition and morphology. From the origin, it belongs to the water erosion landform in the erosion landform, which is accompanied by the features of water accumulation landform, and the erosion landform is further divided into gully landform, forest pillar landform and gully landform. |
