我国土壤系统分类中富铁铝土壤的分类

回顾了我国富铁土和铁铝土分类的历史。我国近代土壤分类开始于30年代;从50年代开始,我国土壤分类深受前苏联地理发生分类的影响。在地理发生分类体系中,按生物气候气候条件,热带、亚热带地带性土壤分别为燥红土、红壤、黄壤、赤红壤和砖红壤。从80年代开始,我国土壤科技工作者结合我国实际,引入了土壤系统分类。这一分类的特点是根据土壤诊断层和诊断特性划分土壤类型。据此,这一区域的地带性土壤主要是富铁土和铁铝土。

The Classification of Ferrallitic Soils in Chinese Soil Txaonomy

Classification of ferrisols and ferralisols were reviewed in the paper. The modern soil classification in China could date back to 1930s. From 1950s, geographical-genetic classification theory originated from the former Soviet Union exerted its extreme impact on soil classification of China. In the geographical-genetic system of soil classification, the zonal soils in the tropical and subtropical China were divided into dry red soils, red soils, yellow soils, laterites and lateritic red soils. Since 1980s, the Soil Taxonomy based on by diagnostic horizons and characteristics of soils was introduced into Chinese soil classification. In Chinese Soil Taxonomy the soils of the tropical and subtropical China could be grouped into ferrisols and ferralisols.
