A study on spatial distribution patterns of soil erosion in loess plateau by rare earth element tracer method

A new method with nuclear technology to study soil erosion amount monitoring on different topography part in loess Plateau is reported in this paper. Experiment results have shown that the method of rare earth element tracing combined with neutron activation analysis (NAA) can be used to quantitativ...

Summary:A new method with nuclear technology to study soil erosion amount monitoring on different topography part in loess Plateau is reported in this paper. Experiment results have shown that the method of rare earth element tracing combined with neutron activation analysis (NAA) can be used to quantitatively determine relative erosion amounts on different topography parts with better precision and sensitivity. It also can be used to reveal the change trend of relative erosion amounts along a slope in erosion processes, as well as the soil erosion distribution patterns
