摘要
本文根据清凉峰土壤的特性，按照“中国土壤系统分类（首次方案）”，讨论了清凉峰土壤的分类问题。清凉峰基带土壤为准红壤，从下而上依次分布着准红壤、准黄壤和腐棕土。准红壤Ｂ层颜色为亮红棕，ＣＥＣ／粘粒％值大于０．２４，Ｂ层粘粒硅铝率小于２．４，粘土矿物以高岭石为主。准黄壤Ｂ层颜色为浊棕色和灰黄棕色。ＣＥＣ／粘粒％值为０．４１－０．４２，粘粒硅铝率为２．３７－２．４９，Ｂ层盐基饱和度小于３５％。腐棕土表层颜色为，黑棕色有机质含量高，为１８３．４克每千克，有机质层厚，粘上矿物以２：１型蛭石和绿泥石为主。
According to the Property of soil and compared with the' Chinese soil Taxo-nomic classification”(Ist proposal),this paper has discussed the classification of soils ofQingliang peak in Anhui. The basic belt of soil in the region of Qingliang peak is that of Para-red soils,thesoil sequence from the peak foot going upwards is in the order of Para-red soils,Para-yellow soils and Humusbrownified soils.
