摘要
庐山土壤实地调查研究和室内分析结果显示,庐山土壤具有明显的垂直地带性及其养分分布规律,随着海拔的升高,土壤类型依次为山地红壤、黄壤、黄棕壤、棕壤、山地草甸土,土壤养分与地面生长的植物类型及其凋落物密切相关,土壤的硅铝率或硅铁铝率均随着海拔的升高逐渐增大,由大到小依次表现为山地草甸土,山地棕壤,山地黄棕壤,山地黄壤,山地红壤。
The results of on-the-spot investigation and indoor analysis of the soils in MT.Lushan,showed that：The soils of MT.Lushan have obvious vertical zonatity and laws of distribution of soil nutrients. With rising of the altitude,the soil types in MT.Lushan are in an order of Red soil,Yellow soil,Yellow-brown soil,Brown soil and Mountain meadow soil,and the content of soil nutrients is closely related to the plant types and their litters. The soil silica-alumina ratio or silica-sesquioxide ratio rises gradually with altitude,its order from small to big is Mountain meadow soils,Mountain Brown soils,Mountain Yellow-brown soils,Mountain Yellow soils,Mountain Red soils.
