Present application status of nuclear monitoring technique, an advanced technique in soil erosion study, is simply described in the paper as well as a new method——stable rare-earth element (REE) monitoring technique——introduced. The new method can be used to quantitatively measure the relative erosion at different landform sites of a slope, reveal the tendency of relative erosion quantity change along the slope in erosion process and reflect soil erosion distribution pattern in whole slope experimental plot...
