通过运用REE示踪法对土壤侵蚀垂直分布的模拟试验研究，讨论了REE示踪法的基本原理，REE的选择与施放方法，模拟试验布设技术及示踪法的应用前景。室内试验表明：REE示踪法不仅可定量测定不同地形部位的相对侵蚀量，而且可揭示降雨过程中各地形部位相对侵蚀量的变化趋势．为野外试验的顺利实施提供了可靠的科学依据。
By using REE tracer method to simulate the vertical distribution of soil erosion, the basic principle of REE tracer method, the selection and application of REE method, the simulation test layout technology and the application prospect of tracer method are discussed. Laboratory tests show that REE tracer method can not only quantitatively measure the relative erosion amount of different topographic parts, but also reveal the trend of relative erosion amount of each topographic part during rainfall. It provides a reliable scientific basis for the smooth implementation of field experiments.
