应用土壤发生学分类体系对大巴山北坡不同海拔高度土壤进行研究，结果表明，发育于不同海拔高度的土壤剖面形态、土壤特性和成土过程存在着明显差异。随海拔高度的变化，土壤性质表现出明显的地理分异。大巴山北坡基带土壤为黄褐土（＜９００ｍ），自下而上依次分布着黄棕壤（９００～１６００ｍ）、棕壤（１６００～２６００ｍ）、暗棕壤（＞２６００ｍ）。此外，本区尚有棕色石灰土及亚高山草甸土的分布 Soil taxonomy was used to study the soil profiles at different altitudes on the northern slope of Daba Mountain. The results showed that there were significant differences in soil profile, soil characteristics and soil-forming processes at different altitudes. With the change of altitude, soil properties showed obvious geographical differentiation. The basement soil in the northern slope of Daba Mountain is yellow-brown soil (<900m). Yellow-brown soil (900-1600m), brown soil (1600-2600m) and dark brown soil (> 2600m) are distributed from bottom to top. In addition, the area has brown lime soil and sub-alpine meadow soil distribution
