植被是气候和土地利用改变地貌过程和地貌的最重要中介。在本文中，我们探索了三种类型的模型，它们试图模拟与未开垦的植被之间的联系，这三种模型在水文学中都有一个共同的基础。第一种是模拟固定地形和土壤覆盖下的气候、植被和侵蚀率之间的关系。第二组模型考虑了与土壤性质的长期相互作用，这被认为在当前关注全球变化的时间尺度上是重要的。这种相互作用的扩展说明是冲刷侵蚀过程、植被覆盖和微地形演变之间的关系。第三组模型着眼于地质时间跨度，气候地区之间植被和地貌的一致差异导致侵蚀速度模式对过去和现在气候的共同反应。
Vegetation is the most important intermediate through which climate and land use modify geomorphological processes and landforms. In this paper we explore three types of model which attempt to simulate the links to uncultivated vegetation, all sharing a common basis in hydrology. The first simulates the relationship between climate, vegetation and erosion rates for a fixed topography and soil cover. The second group of models takes into account longer term interactions with soil properties, which are thought to be important on the times scales of current concern with global change. An expanded illustration of this interaction is the relationship between wash erosion processes, vegetation cover and the evolution of microtopography. The third group of models looks at geological time spans, for which consistent differences in vegetation and landform between climatic areas create responses in the pattern of erosion rates, jointly to a combination of past and present climates.
