摘要
随着核素示踪技术在土壤侵蚀研究中应用的深入,土壤侵蚀研究进入了一个快速发展阶段。本文阐述了近十年来137Cs2、10Pbex7、Be、复合示踪及REE-INAA示踪等几种主要核素示踪技术在土壤侵蚀速率、泥沙沉积速率、泥沙来源和坡面侵蚀过程等研究中的应用新进展,并对今后的研究方向和发展趋势进行了分析。
In the last decade nuclide tracing technique has been widely employed in the investigation of soil erosion, which makes the studieg of soil erosion into a new and rapid development period. This paper tried to review the recent progress of using ^137 Cs, ^210 Pbex ^7Be, composite tracers and REE-INAA in soil erosion rate, sedimentation rate, sediment source and soil erosion processes study, and also the existing research results. The trends for future development and questions are also discussed.
