摘　　要：统计了1985年~2009年3月利用137Cs示踪技术研究土壤侵蚀的国内现有电子资料,并对当前的研究文献做了归纳分析,从背景值、模型、土壤侵蚀的空间变异规律及影响因子等方面阐述了137Cs的研究现状,基于此,对其研究前景进行了展望。The domestic electronic data of 137Cs tracer technique in studying soil corrosion from 1985 to March, 2009 were counted. Current literatures were summed up and analyzed then. The research status of 137 Cs was expounded from the aspects of background value, models, spatial variation pattern of soil erosion and influential factors. On this basis, the research directio of 137Cs was prospected.
