稀土元素示踪技术及其在土壤侵蚀研究中的应用

REE Tracing Method and Application in Soil Erosion

稀土元素示踪技术作为一种研究土壤侵蚀的新方法,被广泛应用于土壤坡面侵蚀和泥沙来源等方面的研究。在对稀土元素布设方法、含量测定方法和精度分析方法进行分析的基础上,对稀土元素示踪技术作了总结。对其在坡面侵蚀以及泥沙运移过程中的研究进行了评述,并在此基础上对稀土元素示踪技术的相关问题进行了探讨,指出了目前这些研究中存在的不足,以便为后期稀土元素示踪技术的改进及其在土壤侵蚀研究中的应用提供一定参考。

REE tracing method, as a new method, is widely used on the research of soil erosion and sediment sources. This paper summarized the REE tracing method based on analysis of REE laying method, determination and accuracy analysis methods. The application of REE tracing method on the slope erosion and sediment transport was also reviewed. The shortcoming of these studies was also pointed out. This paper could provide a scientific reference on improvement of REE tracing method and application in soil erosion more widely.
