- Abstract:
-
Soil physicochemical properties of different depth of Fanjingshan Mountain at different altitudes were investigated to explore the relationship between altitudes and soil physicochemical properties. The contents of soil organic matter, total nitrogen, available nitrogen, total phosphorus and available phosphorus were determined. The results showed that with the increase of depth of soil samples in different altitudes, the contents of soil organic matter, total nitrogen, available nitrogen, total phosphorus, available phosphorus and the ecological stoichiometry decreased. At the different altitudes, there was a significant correlation between elevation and the contents of soil organic matter and available nitrogen in the depth of 0—20 cm due to the factors such as climate, biological and terrain. With the increase of elevation, the contents of soil organic matter increased, then decreased. The highest value appeared at the altitude of 1 450 m. The available nitrogen increased with the increase of elevation. All indicators of the soil in the depth of 20—40 cm had no obvious correlation with elevation. The contents of soil organic matter and total nitrogen, soil C/P and N/P had a significant correlation with the elevation, they increased with the altitude rising in the soil depth of 40—60 cm.
