武夷山不同垂直地带土壤理化性质和土壤类型

通过选取武夷山土壤垂直带中7个代表性剖面，采样进行室内理化分析，对武夷山土壤成土过程以及10项理化指标（pH值、有机质含量、机械组成等）进行分析，研究了初步武夷山土壤理化性质的垂直变化规律，结果表明：武夷山土壤成土条件和理化性质不同垂直地带差异明显，各剖面酸性均较强；有机质的累积随着海拔的升高而增加；土壤中的粘粒含量较高，随海寝上升而逐渐减少。

Physical and Chemical Nature of Soil and soil great group in different vertical zone of Wuyi Mountain

Through selecting 7 representative section of Wuyi mountain soil, collecting typical samples, collecting autoptical information of field and experimental data, and analyzing ten chemical index（ PH value,the content of soil organic matter. the soil ,texture and so on） , vertical variation of physical and chemical nature in Wuyi mountain soil were studied, The resuls showed that soil forming condition and physiccal and chemical property were divided obviously. All section acidity is more strong, The accumulation of organic quality goes up and increase with raise of elevation. The content of clay particles in the soil is higher, but which gradual decrease with organic ascension.
