摘要
根据有关文献资料,从形态、有效性、与侵蚀的关系、影响因素和流失模型等方面,对黄土区土壤钾素径流流失机理的研究作一综述。文章指出进一步深入研究黄土区土壤钾素径流流失机理十分必要。
This paper presents a comprehensive review of the studies on mechanism of soil potassium loss by erosion in loess area, which includes soil potassium form, availability, relation with erosion, influence factor, loss model, etc. It is necessary that mechanism of soil potassium loss by erosion in loess area is studied deeply.
