大巴山北坡垂直带土壤特性及系统分类

通过野外考察与室内分析相结合 ,对大巴山北坡不同海拔高度的土壤特性进行研究 ,确定了各剖面的诊断层和诊断特性及其在系统分类中的位置。结果表明大巴山北坡各垂直带土壤在系统分类中可划归 2个土纲的 6个土类 ,系统分类中土壤的分类位置与发生分类位置并不具有简单的一一对应的关系。

In order to enrich and improve Chinese Soil Taxonomic Classification,and to confirm the classification position of soils in altitudinal belts in the northen slope of Daba mountain,the author investigate the climate ,plant and soil of the northern slope of its highest peak (Hualong Mountain).Through sampling characteristic soil profile in different altitude along with laboratory analysis,some characteristics of soils in different elevation in the northern slope of Daba mountain have been studied.Based on th...
