我国的富铝化土壤,主要包括红壤、赤红壤、砖红壤及黄壤等土类。这类土壤跨越我国热带亚热带,分布面积约200万平方公里,是我国发展粮食、热带亚热带经济作物与林木的重要基地。长期以来,国内外不少土壤学者,曾对富铝化土壤进行过大量研究,但迄今有关这类土壤的成土条件,发生过程及基本属性,特别是与此类土壤分类有关的发生诊断特性与指标仍未能完善地阐明。本文企图根据近几年的研究结果,着重讨论我国富 China’s aluminum-rich soil, including red soil, red soil, brick red soil and yellow soil and other soil. Such soil spans China’s tropical and subtropical areas with an area of ​​about 2 million square kilometers and is an important base for developing food, tropical and subtropical cash crops and trees in China. For a long time, many soil scientists at home and abroad have done a great deal of research on the soil rich in alluvium. However, so far, the soil conditions, occurrence and basic characteristics of this kind of soil, especially the diagnostic characteristics related to such soil classification And the index is still not perfect to clarify. This article attempts to focus on the wealth of our country based on the findings of recent years
