- Abstract:
- In order to analyze the slope-aspect driven variation of soil physicochemical properties and saturated hydraulic conductivity in Dongshan experimental forest farm of Taiyuan City, we selected sunny-slope，half-sunny slope and shady-slope in bare area and forest lands to sample soils, and the basic properties of soil and nutrient contents were measured, we used the core to take soil samples in layers, and measured the soil saturated hydraulic conductivity, explored the characteristic of soil properties, soil nutrient and saturated hydraulic conductivity of samples taken in different aspects. The results showed that the slope aspects had no effect on soil density; soil moisture in bare area decreased in the order: shady-slope > half-sunny slope > sunny-slope; soil moisture, soil nutrients and soil saturated hydraulic conductivity in forest land decreased in the order: characterized by sunny-slope > half-sunny slope > shady-slope, sunny-slope gravel content of surface soil (0—30 cm) is less than the other aspect, and its total porosity is larger than other aspect. Influence of aspect on soil properties and saturated hydraulic conductivity is indirect, which is through its effects on forest. The future research for soil properties and water infiltration in forest land should not ignore the impact of slope aspect.
