研究坡地土壤氮素迁移转化的过程具有重要的科学理论意义和工程应用价值。结合目前国内外研究现状,论述了坡地土壤侵蚀与氮素迁移转化的过程,以及降雨、土壤特性、地表状况、土地利用方式等因素对坡地土壤氮素迁移转化规律的影响。分析得出,坡面地表径流、壤中流和侵蚀泥沙为坡地土壤氮素迁移转化的主要途径。最后围绕坡地土壤氮素迁移转化模型展开了探讨。
Studying the process of soil nitrogen translocation and transformation on sloping land has important scientific and theoretical significance and engineering application value. Combined with the current research status at home and abroad, the process of soil erosion and nitrogen migration and conversion as well as the effects of rainfall, soil characteristics, land surface conditions and land use on soil nitrogen migration and transformation were discussed. The analysis shows that surface runoff, soil inflow and erosion sediment are the main ways of soil nitrogen migration and transformation on sloping land. Finally, the model of soil nitrogen migration and transformation around sloping fields was discussed.
