摘要
鉴于用示踪法研究土壤侵蚀已成为国际社会普遍关注的热点问题,结合国内外最新研究进展,主要介绍了放射性核素示踪(137Cs,210Pbex,7Be,复合核素)、稀土元素(REE)示踪、磁性示踪等3类主要示踪法在土壤侵蚀研究中的应用概况及进展,结合示踪法在土壤侵蚀研究中的特点,分析了示踪法在土壤侵蚀研究中存在的问题以及在今后的发展方向和应用前景。
Tracer method in the study of soil erosion has become the focus of international community,combined with the latest research progress at home and abroad,the paper summarized the applications and progress of radioactive tracer(137Cs,210Pbex,7Be and compound application),rare earth element tracers and magnetic tracers in the field soil erosion.Based on the characteristics of the tracer method in soil erosion study,the prospect and shortcoming of tracer methods has been discussed in detail.
