摘要:
为探明梵净山地区海拔高度与土壤性质间的关系，在不同海拔高度采集不同深度土层土样，测定土壤有机质、全氮、全磷、碱解氮、有效磷含量。结果表明：在不同采样深度下，随着土层深度的增加，土壤有机质、全氮、全磷、碱解氮、有效磷以及碳氮比、碳磷比和氮磷比均逐渐下降。在不同海拔高度下，受气候、生物和地形等因素的影响，0—20 cm层土壤中有机质、碱解氮含量与海拔高度显著相关，有机质含量随海拔的增加呈先增加后下降的趋势，在海拔1 450 m达到最大值，碱解氮含量随海拔的增加而增加；20—40 cm层土壤各项指标与海拔高度相关度不紧密；40—60 cm层土壤中，有机质、全氮含量、碳磷比、氮磷比与海拔高度显著相关，均随海拔的增加而增加。
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.
