- 摘要:
- 通过野外侵蚀小区实验，进一步证明了稀土元素示踪法[4]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。
- Abstract:
- Vertical varlabilityisa basic component of soilerosion on loess slope. Experiments of field erosion Plot were conducted and further support the availability of rare earth elements (REE) tracer method to study the vertical distribution of soil erosion. Experiments on a erosion plot have firstly revealed that vertical distribution pattern of sediment yield have three types that are continued -increasing type. increase -decreasing type and wave type. We have primarily ccnstructed method estimating ratio of rill erosion according to redistribution of REE on loess slope.
