Abstract：The origins of different types of isotopes are introduced. The application of several isotopes as tracer on the studies of soil erosion is also reviewed detailedly. In the past decades man-made radionuclide 137Cs was used as tracer most broadly in soil erosion field. Isotope 210 Pb comes from nature and the veracity of its application on soil erosion do need more consideration. Astro-raus produce many radionuclides and the application of 7Be as tracer on soil erosion is introduced in this paper. The studies of those that stable rare earth elements trace soil erosion process and several nuclides are compounded together to distinguish source of sediment are also summarized and evaluated. Some suggestions about the direction of application of isotopes on soil erosion are proposed.
