Description :
Based on the 137Cs tracer and GIS technology, this study clarified the spatial distribution of erosion and deposition regimes within a small catchment (Dongshan catchment), which has typical representativeness in the black soil region of Northeast China. Slope erosion mainly controlled erosion intensity, but distribution pattern of erosion regime at the slope scale was affected by slope shape. For the convex slope, the most severe erosion location was the back of slope, while for the concave slope it was the shoulder of slope. Gully head made the leading contribution to the gully erosion.
