Abstract

Assessing the benefits of soil and water conservation aims at promoting conservation technology and providing a decision-making basis for eco-construction. Tracing technique by environmental radionuclide can directly determine the net soil erosion within a certain period

and provide information on soil erosion and sedimentation and thire distribution. Therefore

it is a good way for soil erosion assessment. This study tries to use 137Cs

210Pb and 7Be to trace soil erosion at different time scales

and proposes corresponding calculating formulas.
