通过野外侵蚀小区实验，进一步证明了稀土元素示踪法[1]在土壤侵蚀垂直分布研究中的可应用性。在一个侵蚀小区上，实验揭示出产沙强度随坡长存在三种变化模式．增长型，增长一递减型和波动型，其形成机理可能与住流过程有关。利用稀土元素在坡面的再分布、初步建立了治界被面沟蚀率的关系式。稀土元素点穴施效法尚存在问题，有待深入研究。
The experiment of field erosion community further proved the applicability of REE trace method [1] in vertical distribution of soil erosion. On an eroded plot, experiments revealed that there are three patterns of variation in sediment yield with the slope length. Growth-type, growth-decay-type and volatility-type, its formation mechanism may be related to the abortion process. Based on the redistribution of rare earth elements on the slope, the relationship between erosion and erosion rate was established. Rare earth elements acupuncture and applying method still exist problems, pending further study.
