- Abstract:
-
Small gravitational erosion is a very important agent for sediment yield in the gully region of the Loess Plateau. There are many influence factors for the generation of the gravitational erosion. Based on field observation, some factors, such as development stages of the channel, degree of the slope, weathering grade and creeping of the regolith, vegetation, rain and so on, are discussed in this paper. We concluded that weathering grade and creeping of the regolith are important influence factors for the small gravitational erosion. Slope degree is controling facors which determines the intensity and scale of the small gravitational erosion. Rain is important triggering factor for the occurrence of small gravitational erosion. And the development of the vegetation can restrain occurrence of the small gravitation erosion to some extent.
