| Abstract: | Based on the experimental data obtained from the belt discharge of REE tracer and INAA technology in room and field,the probability using this method to study vertical distribution of soil erosion in slope is analyzed.The results indicate that the belt discharge method of REE tracer has good accuracy and can be used to study soil erosion in slope and analyze relative erosion of different zone in slope.The research reveals that there are three models in the degree of sand producing with slope length. |
