Soil and Landform Characteristics Re ated to Lands ide Activity - A Review

摘要

Hilly and mountainous landscapes in all parts of the world are blanketed with soils that vary based on the five state factors of soil formation (Heimsath et al., 2001). Many of these landscapes are not in a state of equilibrium—the processes acting on these landscapes are attempting to reach a state of morphological equilibrium. One of the primary processes involved is soil eroding in a "slide" or movement event. Such events are given many names, including soil creep, mass wasting, mass movements, slumping, debris slides, rockslides, landslides, etc. While some distinction among these terms exists, all of them play a major role in controlling long-term landscape evolution (Fernandes et al., 2004), with the overall effect being material movement downslope. A combination of some or all of these terms will be used in this article, with a universal meaning.
