根据创立的土壤侵蚀定位土芯Ｅｕ示踪新方法，研究了红壤坡地不同土地利用方式下土壤侵蚀的垂直分布规律，介绍了新方法的产生背景和示踪原子选择、示踪用量估算、示踪实施、中子活化及侵蚀结果计算等技术要点，以及在红壤坡地雷竹园的部分应用结果。结果表明，新方法对以片蚀和细沟侵蚀为主的红壤坡地是适用的；在复合坡面，随坡面的陡、缓，土壤侵蚀表现强、弱或沉积，反映了坡地土壤侵蚀的垂直分布规律。
Based on the new Eu tracing method of soil erosion localized soil cores, the vertical distribution of soil erosion under different land use patterns in red soil sloping land was studied. The background of the new method and the selection of tracer atoms, tracer dosage estimation, Implementation, neutron activation and calculation of erosion results and other technical points, as well as the results of partial application of Lei Chuk Yuen in red soil slope. The results show that the new method is suitable for red soil slopes which are mainly eroded by patches of erosion and rill erosion. With the complex slopes, the soil erosion shows strong, weak or sediment, with the steep and gentle slope, reflecting the soil erosion Vertical distribution.
