摘要
采自大别山天堂寨南坡不同海拔高度的土壤样品,测定其粘土矿物组成,发现随着海拔高度的增加,土壤粘粒硅铝率愈往上愈小、占优势的粘粒矿物构型愈往上愈简单、三水钻石在粘粒矿物中所占的比重愈往上愈大。三者相互印证。基于山地土壤中粘土矿物组成的变化可以用来说明它的垂直谱的认识,天堂寨南坡基带土壤黄棕壤以上的土壤,以划为黄壤更为适宜。
Soil samples were collected from different altitude zones of the Tiantangzhai southsloupe in the Dabieshan mountains. The clay mineral constituent in soil was determined.Results indicate: the higher sea level altitude, the less silica-alumina ratio; the moresimple form of predominant soil clay minerals and the biger proportion of gibbsite in theclay minerals. Three of them verify each other. In view of the change of day mineralcomposition in mountain soil may explain the spectrum of soil vertical distribution, soilson the yellow brown soil that is Tiantangzhai south slope basic zonality soil were consi-dered yellow soils.
