摘要
根据庐山的海拔高度(包括气候、母质、植被等成土因素)采用随机分层抽样的方法进行土壤样点分析[1-3],并对结果进行统计处理,通过其差异性对比,得出不同海拔高度发育的土壤速效钾的垂直分布特征以及同一土壤不同土层速效钾含量的分布特征。结果表明:不同海拔高度的土壤中的速效钾的含量与高度成负相关,随着海拔的增高,速效钾的含量逐渐减少,为红壤>山地黄棕壤>山地棕壤。同一土壤不同土层的速效钾含量与深度成负相关,随着深度的增加,速效钾的含量逐渐减少,为A>B>C层。
Adopt the method of the random layering samples to analysis soil samples[1-31 ,according to the elevation height（including the factor of fashioning soil,as weather, female quality and vcgetation＇s etc. ） of Lu shah Mountains, and sum up and handle the results through contrasting its difference,then get vertical distribution characteristics of soil（which develops in the different elevation height ） available potassium and the vertical distribution characteristics of the content of available potassium of the different soil arrangement in the same soil.The result is： The content of soil available potassium in the different elevation height is negative related with height,and the content of available potassium reduces gradually along with increase of elevation height, as Saiyang red soil〉hilly yellow brown soil〉hilly brown soil. The content of available potassium of the different soil arrangement in the same soil is negative related with depth, the content of available potassium reduces gradually along with the increase of the depth, as A〉B〉C arrangement
