摘要:
选择湘中具有代表性的紫色丘陵区——衡南县工联村作为研究区，研究不同覆被下和不同侵蚀坡地的紫色剖面分层土壤的有机质和氮、磷、钾等养分状况。结果表明，该区以酸性紫色土和中性紫色土为主；有机质、氮含量低；磷、钾相对要高；侵蚀性土体土壤养分性状与土体所处坡度、坡位、覆盖植被类型有关；坡顶、坡中土壤由于冲刷剥离、搬运扩散作用强烈，理化性质恶化，而坡底掩埋沉积占主导作用，仍保持良好的土壤性质。不同植被类型同一层土壤比较，其养分含量变化总体趋势：灌木>乔木>杂草>旱地。
Abstract:
In this paper, the typical village of Gonglian village of Hengnan County in purple hilly region was chosen to study nutrient characteristics of the erosive purple soil with different cover-plant and different slopes. The aims are to study organic matter, nitrogen, phosphorus, potassium and other nutrients, density and porosity of the soil. The results showed that the area mainly is acid purple soil and neutral purple soil, organic matter, nitrogen content is low relative to high phosphorus and potassium. Soil physical and chemical properties of erosive soil is relative to its slope, slope position, vegetation types. The slope of soil erosion in the chosen region due to stripping, handling strong role in the proliferation, deterioration of physical and chemical properties, and the foot of the slope buried deposition of a leading role, still maintain good nature of the soil. Different types of vegetation with a layer of soil, its nutrient content in the overall trend: shrubs>tree>weeds>dry.
