摘　　要：土壤侵蚀研究的 13 7Cs法具有简单、快速、准确的优点 ,目前已广泛应用于土壤侵蚀和泥沙来源研究。中国土壤侵蚀的 13 7Cs法研究经历了 :模仿与个体探索、群体深入研究和国际合作研究、推广应用几个阶段。在世界上占据了应有的地位。中国 13 7Cs研究主要集中于 :13 7Cs本底值、土壤侵蚀量计算模型、土壤侵蚀速率和相对产沙量等几个方面。今后 13 7Cs与其他核素结合研究土壤侵蚀 。Cs is an important radionuclide tracer, and 137 Cs measurement has been widely used in soil erosion and relative sediment source researches because of its convenience, swiftness and accuracy. 137 Cs technique in China has experienced four stages as follow: imitation and individual exploration, group research, international cooperation and wide utilization. China has owned its standing in this field in the world. The key researches focus on the reference inventory of 137 Cs, the models of soil erosion, erosion rates and relative sediment sources. If 137 Cs can be combined with other tracers using in soil erosion, 137 Cs technique will have a prosperous future.
