陽明山磚紅化土與黑色安山岩土之生成關係研究

Abstract

本研究係就北部大屯火山彙相同母質所育成之三土類，紅棕壤，黑色安山岩土與灰棕壤，研究其理化性質，並探討其生成間之關係，選取四代表剖面，進行其理化分析，包括之項目有土色，機械組成、pH、有機質、全氮量、陽離子交換性質、土壤全量分析及粘土部分之SiO2/R2O3。分析等八項目，結果摘要如下： Three soil groups (reddish brown latosols, black andesite soils and gray brown podzolic soils) which are developing from the same parent materials (andesite or andesitic agglomerate and other pyroclastics) have studied on their physico-chemical properties and the correlation of their development. Four soil representative profiles were collected. Items of this experiment consist of mechanical analysis, pH, organic matter, total nitrogen, cation exchange properties, total analysis of the whole soils and the SiO2/R2O3 of the clay fraction etc..
