| Abstract: | The isotope tracer technique has been widely used in soil erosion research because of its convenience,swiftness and accuracy.This paper first simply summarizes the methods of measuring soil erosion rate,then reviews the application of 137 Cs method on soil erosion study and its present situation,and pays more attention to the spacial distributing of 137 Cs,the models of soil erosion rate,and the appraisable models of soil erosion,et al.Lastly,the paper sets forth the development trend of the study of soil erosion by 137 Cs. |
