From above to below, the erosion types ordinally are sheeterosion, gravitational erosion, rill erosion, gully erosion, sediment.
自上到下侵蚀主要表现为片蚀、重力侵蚀、细沟侵蚀、切沟侵蚀、冲沟侵蚀、沉积。

In this paper, a new REE tracer method was given to quantitatively distinguish the sheeterosion amount and the rill erosion amount, and it would be a new method to study the erosion process on slope.
The results indicate that the main erosion type is sheeterosion at the beginning of the rainfalls, and serious erosion happens after rill erosion appeared.
