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 point. The radionuclides trace technique possesses lots of advantages, and has wide application prospects in future. This paper introduces the principle of the 210Pbex tracing technique, and reviews the existing vital problems of the 210Pbex tracing technique, broad application in soil erosion studies, and application prospects in future as well.
