For tackling the rare earth element (REE)tracing method of small watershed erosion researching, the slope-gully model REE tracing method was carried by the simulated rainfall experiment. The result showed that we can use spot method taking REE on the gully region with the slope gradient stepness and the runoff intensity big, but before taking, we must mix REE with the soil,using pure REE is very difficult. Based On this,we Suggested that we can use grid method to select spot in the observation of small wate...
