| 摘 要： | 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。

| Abstract: | 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 the Chinese Soil Taxonomy (Revised proposal),the diagnostic horizons and diagnostic characteristics of several soil profiles as well as its taxonomic classification category have also been defined.The results show that there are six groups (Matcryic Cambisols,Umbcryic Cambisols,Happerudic Cambisols,Molperydic Cambisols,Ferudic Luvisols and Arpudic Luvisols) included in two orde (Cambisols and Lurisols) in altitudinal belt in the northern slope of Daba mountain.Compared with soil genesis and classification,the taxonomic classification category does not correspond simply to that of the genetic classification. |
