- 摘要:
- 环境放射性核素7Be、137Cs和210Pb为测量土壤侵蚀和沉积速率提供了一种重要的方法。在某些情况下，由于受各种因素的影响，单一核素进行示踪研究很难精确测量，而核素比率的方法作为有益的补充，能够精确测量土壤侵蚀量的多少。这篇文章介绍Wallbrink和Murray在St.Helens森林区用210Pbex/137Cs方法测量土壤侵蚀的情况，了解国外的研究动态，对此也提出在应用核素比率法中应注意的问题和展望。
- Abstract:
- The environmental radionuclides 7Be, 137Cs and 210Pb for documenting soil erosion and sendiment rates provides an important method. However there are environments in which it is difficult for only one radionuclide to document soil erosion accurately because of other factors. Using the inventory ratio of excess 210Pb to 137Cs to measure soil loss accurately is complementary method. It describes that Wallbrink and Murray use the inventory ratio of excess 210Pb to 137Cs to measure soil loss in St. Helens forest, know abroad study on recent progress, and provide good suggestion on this method.
