大别山北坡土壤的发生特性和垂直分布

GENETIC CHARACTERISTICS AND VERTICAL DISTRIBUTION OF SOILS ON NORTH SLOPE OF DABIE MOUNTAINS

本文在豫南大别山北坡的土壤野外考察的基础上，研究了土壤形成的自然条件、发生特性。结果表明，土壤的垂直带谱为：黄棕壤→暗黄棕壤→酸性棕壤→山地灌丛草甸土。并根据“中国土壤系统分类”进行了土壤诊断分类的尝试。

Ths paper deals with the particle fraction, chemical properties, the total chemical composition of fine earth and day fractions, and the patterns of clay minerals in eight soil profiles on the north slope of Mt. Dabie in Henan Province. The results indicated that the basic belt of soil in the region of Mt. Dabie is that of yellow-brown soils, and the soils equence going upwards from the mountain foot is in the order of yellow-brown soils→ add brown soils→dark yellow →brown soils→acid brown soils→mountain shrubby meadow soils. According to the Chinese Soil Taxonomic Classification, the soils are indentified and classified.
