Progress of Studying Soil Erosion Process on the Loess Plateau of China

摘要

The Loess Plateau has the highest erosion rates in the world. Study on soil erosion process in the Loess Plateau has received more attention in recent years. Soil erosion on gullied rolling loess plateau has clear sheet zone, rill zone and shallow gully zone from watershed to gully edge. Vertical erosion distribution zone is an important feature on the loess plateau. Infiltration, sediment concentration, erosion pattern and characteristic of sediment and water transportation have a clear distribution too. So, spatial variability of slope erosion pattern, sheet, rill, shallow gully and permanent gully erosion process dominated at different erosion zone as well as slope gully coupling system were discussed in this paper. And then, further research issues have been presented in the future.
