- Abstract:
-
Tracer methods has been used to study soil erosion for about 30 years. With low analytical error and high quantification, it is also able to monitor quantitatively the both temporal and spatial variation of soil erosion.The single application of 137Cs and compound application of 7Be, 210Pb, 226Ra, 230Th, 137Cs in the field of soil erosion and sediment sources are reviewed. REE tracer method could perfectly describe the sediment sources, and be an effective method for studying temporal and spatial distribution of erosion and sediment. Finally both advantages and limitations of all these methods are discussed.
