| Abstract: | The paper briefly introduces the application of ~(137)Cs tracer method in soil erosion study, including the basic principles of ~(137)Cs tracing and models in common use for soil erosion of cultivated and non-cultivated lands, such as index distribution model of non-cultivated lands, proportionality model of cultivated lands, capacity model and quality balance model. The paper also conducts correlation and analysis on modeling of hypothesis, calculation formula and applied limitation for the above cultivated land models. |
