英文摘要:

      :Soil erosion is one of the environmental problems over the world, which seriously threatens the sustainable development of resources, environment and social economy. Studying soil erosion using radionuclides trace technique has become one hot topic. The radionuclides trace technique possesses lots of advantages, and has wide application prospects in future. In the present paper,we introduced the principle of the ²¹⁰Pb_ex tracing technique, and reviewed the existing vital problems of the²¹⁰Pb_extracing technique, broad application in soil erosion studies, and Listed application prospects in future as well.
