摘要

本文着重探讨中国土壤系统分类高级单元的分布规律.研究结果表明,在已确立的14个土纲中,有6种呈现出规则性连续分布,还可以划分出干旱、干润和湿润三大系列的土壤,其它8种构成地域性间断分布.此外,在山地还表现出土壤垂直分布.

Abstract

Characteristics of special distribution of the categories in Chinese Soil Taxonomy were studied through analyzing the diag-nostic horizons and diagnostic characteristics and their relations to the variation of the various soil-forming factors in China, and using soil mapping technology. Results indicate that the distribution characteristics of the higher categories in Chinese Soil Taxonomy are different from the past used zonal distribution which are inferred based on the relationships among typical profiles and bio-climatic conditions. Among the fourteen soil orders, there are six belonging to the basic type, which show regu-larly continuous distribution and can be divided into three large soil series: aridic, ustic and udic soils. The other eight soil orders belong to the special type, with band-shaped, spot-shaped, chessboard-shaped, patch-shaped, distributions. Moreover, there is a vertical distribution characteristic in mountains.
