摘要

为了探究海拔高度与土壤理化性质之间的关系

对秦岭火地塘林区不同海拔高度土壤理化性质进行研究。在不同海拔高度设置样地

对土壤进行分层取样

室内测定土壤pH值、有机质、全氮、全磷、全钾、有效氮、有效磷和有效钾含量。结果表明:(1)在不同采样深度下

随着土壤深度增加

除土壤pH值逐渐升高外

有机质、全氮、有效磷和有效钾的含量逐渐降低

其他指标无明显变化规律;(2)土壤pH值、有机质、全氮和有效磷含量与海拔之间有显著的相关关系

土壤pH值随海拔升高先逐渐升高

最高点出现在海拔1 800～2 000m

后随海拔升高逐渐降低;有机质、全氮含量随着海拔升高而升高;有效磷含量随海拔升高而下降;有效氮、全磷、全钾和有效钾的含量和海拔之间不存在明显的相关关系。该林区应结合当地森林植被类型状况

针对不同海拔林地土壤的特点

调整林分模式

改善林地土壤性质

以维护该区林地的可持续发展。

Abstract

Soil physicochemical properties of Huoditang in different altitudes were researched for exploring the relationship between altitude and soil physicochemical properties.Stratified to get soil sample

the content of soil organic matter

total nitrogen

available nitrogen

total phosphorus

available phosphorus

total potassium

available potassium and pH were determined.The results showed that:(1) With the increase of section depth of soil samples in the different altitudes

pH appeared gradually increase

but the con...
