| 摘 要： | 本文阐述了北亚热带过渡区十个土壤剖面的成土条件和基本性质，应用模糊聚类对土壤的五项诊断指标进行了分析，并与发生分类和诊断分类相比较．在中国土壤系统分类中提出建立淋溶土纲和始成土纲的基础上，探讨了供试土壤的分类地位。其中０１－０４号剖面属于典型铁质湿润淋溶上亚类；０５—０７和０９号剖面归为铁质粘磐半干润淋溶土亚类；０８号剖面为典型半干润淡色始成上亚类，１０号剖面为典型淡色滞水淋溶士亚类。

| Abstract: | The paper deals with the soil-formation conditions, basic properties of ten soil profiles in transition regions of northern subtropics. Fuzzy cluster is applied to analyse five diagnostic indexes of soils. The soils have been identified and compared according to the genetic classification and diagnostic classification. It is suggested to establish Alfisol and Inceptisol order in Chinese Soil Taxonomic Classification. The result shows that the profiles of No. 01-04 belong to Typic Ferric Aqualfs; No. 05-07 and No. 09 are Ferric Claypanic Ustalfs; No. 08 is Typic Ustochrepts; No. 10 is Typic Stagnic Ochralfs. |
