植被根系与土壤抗蚀抗冲性的关系主要体现在两方面:一是根系改善了土壤的物理性质,增加入渗;二是根系的结构布局和形态特征,从力学方面考虑,具有提高土壤抗蚀抗冲性的功能。文章从植被根系、土壤抗蚀抗冲性和及二者的关系三方面,综述了典型的乔、灌、草和作物根系研究发展概况和在土体中的分布规律及提高土壤抗蚀抗冲性的相关因素和力学机制,重点突出了细根(D<2mm)在提高土壤抗蚀抗冲性中的重要作用,同时探讨了今后的研究内容。
The relationship between vegetation root system and soil erosion resistance is mainly reflected in two aspects: one is that the root system improves the physical properties of the soil and increases the infiltration; the other is the structural layout and morphological characteristics of the root system. From the aspect of mechanics, Erosion-resistant features. The article summarized the research development of the root system and its distribution in the soil from three aspects of the vegetation root system, the soil erosion resistance and the relationship between them and the improvement of soil erosion resistance Related factors and mechanical mechanism, highlighting the important role of fine roots (D <2mm) in improving soil erosion resistance and the future research content.
