In this paper the dynamic changing process of soil erosion time and spatial distributive characteristics on slope surface was studied by the rare earth element(REE) tracing method. The results show that the REE tracing method can be used to precisely determine the relative erosion amount on different topographical parts in slope surface, and to reveal the changing trends of erosion amount on the different part in the process of soil erosion. It was concluded that the distribution pattern of erosion with the...
