摘要
同位素1 37Cs示踪技术具有简单、快速、准确的优点 ,它已广泛应用于土壤侵蚀的研究中 .本文先简单概述了现代土壤侵蚀速率的研究方法 ,然后着重综述了1 37Cs法在土壤侵蚀研究中的应用及其研究进展 (主要集中在1 37Cs的空间分布、土壤侵蚀速率计算模型、土壤侵蚀量估算模型等方面 ) ,最后提出未来1
The isotope tracer technique has been widely used in soil erosion research because of its convenience\,swiftness and accuracy.This paper first simply summarizes the methods of measuring soil erosion rate,then reviews the application of 137 Cs method on soil erosion study and its present situation,and pays more attention to the spacial distributing of 137 Cs,the models of soil erosion rate,and the appraisable models of soil erosion,et al.Lastly,the paper sets forth the development trend of the study of soil erosion by 137 Cs.
