- 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.
