摘要
本文对广东坡地红壤颗粒组成的特征进行了初步研究、结果表明；广东坡地红壤较粗颗粒的矿物组成以轻矿物石英为主；粘粒的矿物组成一般以1：1高岭土为主；在粘粒的化学组成中，盐基淋失严重，铁铝氧化物聚积：颗粒大小分布主要受成土母质的影响。
This paper deals with the particle composition characteristics of red soils on slope land of Guangdong. It is found that the coarse particle is mainly composed of light mineral of quartz; clay mineral is dominated by 1:1 type mineral of kaolinite; and the chemical composition of clay is characterized by lower base ratio and accumulation of ferrallitic oxide. Moreover, the particle composition is greatly affected by parent rock types.
