我国紫色土的系统分类与发生分类参比研究

该文首先对紫色土的分布、成土条件及形成特点进行简要介绍,进而对紫色土系统分类和发生分类进行了参比分析,然后对发生分类下同一亚类典型分布点土壤理化性质相关数据进行了分析,得出结论:相较于土壤发生分类,系统分类各级分类单元的分类标准更为明确具体,实际应用价值更大。

Systematic-classification and Occurrence-classification of Purple Soil in China

Firstly,the distribution of purple soil,the formation of soil conditions and the characteristics were instruct?ed briefly in this study. Then the systematic-classification and occurrence-classification of purple soil were ana?lyzed. Then the data of the soil physical and chemical properties under the same sub-classification of typical distri?bution points were analyzed. The result showed that the taxonomy classification system at all levels is more clear and specific taxa under systematic-classification,compared with the soil occurrence-classification. The practical appli?cation value of systematic-classification was bigger.
