| 摘 要： | 坡耕地水土流失问题问题是制约生态农业建设与可持续发展的重要因素，探讨坡耕地土壤侵蚀过程和土壤退化机制是解决问题的关键。基于这些问题，本文应用人工模拟降雨试验方法，研究了坡耕地壤侵蚀发生发展过程，以及侵蚀过程中土壤物理化学特性的演变规律；明确了不同中下坡面单位时间产沙三个过程特征；揭示了泥沙中不同粒级颗粒组成、团聚体和营养元素迁移规律及导致土壤退化加剧的原因；提出了防止坡耕地土壤侵蚀的方法。

| Abstract: | The problem of soil and water loss in the sloping farmland is a principal factor is to restrict eco-agriculture construction and sustainable development. The key of solved problem is to study and discuss that soil erosion process of sloping farmland and soil degradation mechanism. In this paper, the soil process of sloping farmland and the evolution law of soil phsicochemistry properties in soil erosion process has been studied, using simulated rainfall experiment. It also has been analysed the three process characteristics of erosion and sediment in different rainfall intensity. And the transport law of nutrient elements, aggregate and particle size distribution in sediment. The effective way to reduce soil erosion from sloping farmland has been put forward. |
