摘　　要：以秦岭主峰太白山南坡基带与海拔 1 6 0 0 m以下土壤为对象 ,选取典型剖面进行系统的发生特性及分类研究。结果表明 ,供试土壤粘化作用较强 ,形成了明显的粘化层 ;表层腐殖质含量较高 ,土壤呈中性到微酸性反应 ,盐基饱和度较低 ,淋溶作用强烈 ;具有温性土壤温度和湿润土壤水分状况 ,其中基带土壤具有铁质特性 ,属铁质湿润淋溶土 ,海拔 1 6 0 0Two siol typical profiles of base zone and zone with an altitude <1 600 m on the southern slope of the Taibai Mountaint were selected to carry out system study.The results showed that the experimental soils have strong clayization,have already formed Argic Horizon;and have the nature of high surface humus,medium and slight acid reaction,low BS,strong soil leaching;mesic soil temperature regime and Udic soil moisture regime.The base zone soil has Ferric property.According to the Chinese Soil Taxonomy (Revised Proposal),the base zone soil belongs to Fer Udic Luvisols group and the soil of 1 600 m belongs to Hap Udic Luvisols group on the southern slope of the Taibai Mountain.
