| 摘要: |
| 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(900～1 600m)、棕壤(1 600～2 600m)、暗棕壤(>2 600m)。此外,本区尚有棕色石灰土及亚高山草甸土的分布。 |

| Abstract: |
| By means of genetic classification, the soils at different altitudes on the
north slope of Dabashan Mountains have been studied.The soils developed in different
altitudes are significantly different in profile morphologies, pedogenic processes and soil
characteristics.With the change of vertical zonality of soil types, their properties are also
evident in the regularities of geographic differentiation.And the soil vertical distribution
is in the order of yellow-cinnanon soil (<900m), yellow brown soil ( 900～1 600m ),
brown soils (1600～2600) and dark brown soil (> 2 600 m). Besides, brown rendzina
and subalpine meadow soil in this region is also scattered. |
