摘要

利用最新建立的1:100万中国土壤数据库，研究了我国铁铝土的发生分类与中国土壤系统分类的参比及其在中国土壤系统分类中的空间和数量特征。结果表明：我国发生分类铁铝土总面积为1122 969.6 km2，地带性分布规律明显；与发生分类铁铝土参比的中国土壤系统分类土纲有富铁土、淋溶土、雏形土、铁铝土、新成土和变性土6个，它们分别占发生分类铁铝土总面积的34.8%、32.2%、26.1%、6.3%、0.6%、0.04%，其中包含了25个土类和53个亚类，参比关系复杂，空间分布规律不明显。分析各类型土壤参比的面积及其标准偏差，结果表明土壤参比的单元级别越低，越易于参比和把握。虽然中国土壤系统分类研究已经完成了中、高级土壤分类单元的划分，但为使中国土壤系统分类更实用、更易于普及，深入开展土壤基层分类研究，进一步发展和完善中国土壤系统分类是必要的，也是十分迫切的。研究结果对于土壤类型的正确参比、中国土壤系统分类的应用与发展，具有很好的参考应用价值。

Abstract

References between Genetic Soil Classification of China (GSCC) and Chinese Soil Taxonomy (CST), characteristics of distribution of GSCC-Ferralosols in CST were studied, based on 1:100M Soil Database of China. GSCC-Ferralosol is a type of zonal soil with a total area of 1,122,969.6 km2 in China. There are 6 CST Orders referenced with GSCC-Ferralosols, including 25 CST Groups and 53 CST Subgroups, such as Ferrosols, Argosols, Cambosols, Ferralosols, Primosols and Vertosols, in percentages of total area of GSCC-Ferralosols respectively 34.8, 32.2, 26.1, 6.3, 0.6 and 0.04. The reference relationship between GSCC and CST was so complicated that there were no obvious distribution rules for the GSCC-Ferralosols in CST. Results obtained from statistics of references area of the soils in CST show that it is easier to grasp references if the references are all at lower level for both GSCC and CST. Although CST has been finished at high level, it is important and urgent to study and develop the CST at basic level, in order that the CST can be widely used. The result is also useful for soil reference and application of CST.

Key words： soil reference; soil classification; ferralosols; China
