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。 Through the combination of field investigation and laboratory analysis, the soil characteristics at different altitudes along the northern slope of Daba Mountain were studied, and the diagnostic layers and diagnostic characteristics of each section and their positions in the system classification were determined. The results show that the soil in the vertical belt along the northern slope of Daba Mountain can be classified into 6 soil classes in 2 soil classes in the systematic classification. There is no simple one-to-one correspondence between the soil classification positions and the occurrence classification positions in the systematic classification.
