| 摘要: |
| 根据野外调查资料和典型土壤剖面理化性质室内化验数据综合分析表明，太白山北坡基带土壤腐殖质累积较弱，淋溶作用中等，土壤溶液呈中性反应，阳离子代换能力强，盐基饱和度高；剖面分化发育好，形成具有典型硅铝特性的粘化B层，铁的游离度低而活化度高，土壤风化弱，发育程度较低。基带土壤属于系统分类中的简育干润淋溶土土类、普通简育干润淋溶土亚类。 |

| Abstract: |
| The comprehensive analysis results of the out-door investigation data and in-door test data of physical and chemical properties of soil profile showed that the base zone soil in the northern slope of the Taibai Motintain has the proterties of weak acctimulation of htimusl,medium soil leaching,neutral reaction of soil solution,strong carlon exchange capacity,hish BS,well-developed profile dissosiation,already-formed argillic B Horizon with typic siallic property,low Fed/Fet and high Feo/Fed,low degree of weathering and development.The base zone soil is classified as the Hap Ustic Luvisols grotip and Typ Hap Ustic Luvisols subgrotip in the Chinese Soil Taxonomy(Revised Proposal). |
