利用放射性核素示踪环境地球化学过程是国际地球科学的前缘课题。介绍了利用宇宙线成因的短寿命散落核素⁷Be示踪土壤季节性侵蚀及其与湖泊沉积耦合关系的最新研究进展；证实了利用核爆炸散落核素¹³⁷Cs示踪累计性土壤侵蚀和沉积计年的可靠性；阐述了²²⁶Ra和²²⁸Ra在土壤中比活度的形态变化分异具有很好的侵蚀－堆积示踪价值；揭示了在不同生物化学条件下，²¹⁰Pb的行为特征和影响因素，并将²¹⁰Pb_ex示踪碳酸盐岩区域土壤侵蚀速率结果与湖泊沉积速率相耦合，证明了利用²¹⁰Pb示踪土壤侵蚀的可行性。

In this paper, we described the latest progress in the study on seasonal surface soil erosion and its coupling relationship to lake sedimentation using ⁷Be. Meanwhile,¹³⁷Cs reliability for tracing soil particle accumulation and for sediment dating was confirmed. Differentiation of ²²⁶Ra/²²⁸Ra activity ratios in different geochemical fractions in the soils could be used as a parameter to trace accumulation and/or erosion of soil particles. ²¹⁰Pb geochemical behaviour in the soils and sediments and its effecting factors was studied under different conditions. The coupling relationship between soil erosion rates traced by ²¹⁰Pb and lake sediment ation proved that ²¹⁰Pb was reliable for tracing accumulation rate of soil particles.

Key words: Environmental geochemistry, Soil erosion, Radionuclide trace, Yunnan-Guizhou Plateau.
