| 摘 要： | 近几十年来,土壤侵蚀日益加剧,伴随着土地质量的退化,已成为影响区域可持续发展的主要环境问题。利用放射性核素137Cs进行土壤侵蚀研究能够简便、快速、准确地获取土壤流失、沉积和空间重新分布等详细信息。从元素来源、空间分布、背景值、示踪原理、活度测定、转换模型等方面对该方法进行了详细描述,在总结其优缺点的基础上,对其未来的发展方向做出了展望。 |

| Abstract: | In recent decades,the increasing soil erosion and the quality of land degradation has become the main influence of regional sustainable development.Using the radioactive fallout 137Cs as a tracer to study soil erosion can quickly and easily get the information about soil erosion,deposition and the space distribution.This paper introduces the element source,the space distribution,the background value and tracer principle,the activity determination and the transformation model of the methods.Based on the advantages and disadvantages,a prospect for the development direction in the future were given. |
