摘  要:
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。

摘  要:
Based on a stLldy of simulationexperiments for soil erosion vertical distributionby means of rare earth element(REE ) tracer method, basic principles of the tracer method, choice and discharge of REE tracers are discussed in this paper. The technology of experimental design and application futureof the method are also presented. Results from the experiments have shown that the REE method is able not only quantitativelyto determine relative soil erosion amounts on different topography locations, but also to reveal change tendency of relative erosion amountson different locations. and to provicle reliable scientific bases for the carrying out field experiments successfully .
