摘要
讨论了广东坡地红壤类土壤颗粒组成的空间分异现象，阐述了岩性、地形条件、水文动力学对颗粒组成空间分布的影响，指出地形条件、水动力学作用对广东坡地红壤类土壤颗粒组成的影响，在很大程度上是由广东所处区域的生物气候条件决定的。
The paper deals with the characteristics of spatial variation of particle composition of red soils in Guangdong; and theducts of parent rock. landform condition and hydrological kineties on the spatial variation of particle composition of redsoils. It is pointed out that the spatial variation of particle composition of red soils in Guangdong is resulted from theinteraction between the factors of parent rock, landform condition. hydrological kinetics and the special bioclimaticcondition of the region.
