Experimental Study on Soil Erosion by Stable Rare Earth Element Tracer Method

作为研究土壤侵蚀垂直分布的新方法，较详细地描述了稳定性稀土元素(REE)示踪法的原理与操作技术；通过实例说明了诸如示踪元素的选择原则、施放量的计算、施放方法及其注意事项等实际应用中可能遇到的各种问题的解决办法；给出了该方法的精度计算公式。

Stable REE tracer method,as a new method for studies of soil erosion intensity vertical distribution,has been proposed and adopted in this study,especially for its experimental method and operating techniques.The troubles that may be met in practice and the resoluble ways have been discussed by examples.A formula for calculating precision has been also given.
