【摘要】 利用环境核素137Cs示踪技术研究土壤侵蚀被越来越多的科研人员所采用,而背景值的确定是利用该技术研究土壤侵蚀的前提和根本,直接关系到侵蚀速率计算的准确与否。本文从137Cs背景值采样点的选取方式,137Cs全球空间分布预报模型以及影响137Cs沉降因素等方面进行了总结性综述,对137Cs背景值研究应注意的问题和今后研究重点提出了建议。

【Abstract】 Radionuclide fallout()137Cs has been applied in soil erosion research by more and more researchers.However,confirmation of the()137Cs background value was the premise and foundation of whether the results of soil erosion rates were correct or not,provided by using()137Cs tracer technique.The current research results,including how to choose the()137Cs reference sites,the()137Cs reference inventory prediction model of global spatial distribution and the factors affecting the deposition of(()137Cs) were reviewed.Finally,the problems,suggestions and prospects for future development in()137Cs reference inventory were discussed.
