摘要:
利用放射性核素示踪研究土壤侵蚀已成为国际社会普遍关注的热点问题。7Be作为一种自然产生的，短寿命的（半衰期53.3d）放射性核素，具有特殊的示踪价值。介绍了7Be的来源、散落特征及其在土壤颗粒中的存在形态，阐述了7Be示踪技术现有的土壤侵蚀速率定量估算模型，提出了我国开展7Be示踪土壤侵蚀过程研究的建议。
Abstract:
Application of radionulide as a tracer to study soil erosion is a hot spot in the world. 7Be is an environmental or fallout radionulide with a half-life of 53.3 days, which confirmed its particular trace value. The authors introduced 7Be origin source, fallout characteristics, forms in soil particles, and presented quantitative estimate model of soil erosion rate by using 7Be as a tracer. The comments on using 7Be as tracer for soil erosion research in China are presented.
