紫色沉积岩成土类型及其性状

TYPES AND CHARACTERS OF PURPLE SEDIMENTARY ROCK-FORMING SOIL

紫色沉积岩分布地区,并非象以前研究的那样,只存在发育很浅的幼年土。在各种成土条件的作用下,紫色幼年土已在向该区地带性土壤发展,出现了不同发育度的土壤类型。本文通过与马亚热带地带性黄壤、红壤的对比研究,肯定了紫色岩区存在不同发育度的富铝化土壤并对其分类提出了建议。

On the basis of analysing soil forming conditions and processes in regions with the pur-ple rock and in comparison with zonal yellow and red soils in the subtropical zone,alliticsoil in different degree of development is found in the regions.Its classification is discussed.
