摘要： 本文以贡嘎山东坡和九寨沟自然保护区的暗针叶林下发育的土壤为例，研究其发生学特征，运用中国土壤系统分类方法作了新的分类尝试。结果表明，这类土壤存在有机酸的络合淋溶和淀积作用，表层泥炭积累明显。具有有机土壤物质聚积现象及灰化淀积层和漂白层的诊断表下层，将其归属灰土土纲、正常灰土亚纲、灰壤土类、泥炭灰壤亚类。

关键词: 灰土, 灰化作用, 暗针叶林, 西南高山地区

Abstract: This paper takes the soils below dark coniferous forests on the east slope of Gongga Mountains and in the Jiuzhaigou natural protection regions as an example. Studies on the soil genetic properties were conducted and a new attempt on the soil classification with the method of Chinese soil taxonomic classification was taken. The result shows that these soils have chelation, eluviation and illuviation of organic acids and the peats gather together obviously to the surface horizon. They have histic evidence and diagnostic subsurface horizons──the spodic horizon and albic horizon. Therefore,they belong to spodosol order, orthic spodosol suborder. podzol group, peatic podzol subgroup.

Key words: spodosols, podzolization, dark coniferous forests, the high mountains in southwest China
