介绍了应用REE示踪法研究土壤侵蚀的中子活化分析方法。试验结果表明，与REE示踪法相结合的中子活化分析技术，用以定量地测定各种不同地形部位的相对侵蚀量，具有较高的精确度及灵敏度，其相对误差均小于15％。室内外试验分析结果证明了该方法为土壤侵蚀的量化研究提供可靠的分析手段。
The method of neutron activation analysis for soil erosion using REE tracer method is introduced. The experimental results show that the neutron activation analysis combined with REE tracing method can be used to quantitatively measure the relative erosion of different topographic parts with high accuracy and sensitivity, and the relative errors are less than 15%. The results of indoor and outdoor experiments prove that this method can provide a reliable analytical method for quantitative analysis of soil erosion.
