摘要
西藏东南部的南迦巴瓦峰地区,面积约6.43×10 ̄4km ̄2。文章探讨了土壤垂直带谱的性质和结构特点,土壤水平地带与垂直带的关系,土壤垂直带的结构类型;论述了湿润程度、逆温、人类活动对土壤垂直带的影响,以及山体高度和大小与山地土壤分布的关系。
Mt.Namjabarwa,7782 m above sea level,is situated at the eastern
tip of theHimalaya Range. The regularities of soil geographic distribution in this area
aresummarized as follows:1.The vertical zones of soil on the southern slope belong to a
marine humidtype,the vertical spectrum are composed of latored yellow earth(500-1100
m),yellow earth(1 100-1900 m),yellow brown earth(1900-2300 m),grey brown earth(2300-2800m),
podzol(2800-3600m),grey-sod soil(3600-3900m),frost-sod soil(3900-4300 m),and alpine frost
desert soil(4300-4800 m ). Owing to the differe-nce in heat and moisture,the spectrum on the
southern slope differs from that onthe brown earth(2800-3200 m),podzol(3200- 4200 m),
grey-sod soil(4100-4500m),frost-sod soil(4500-4700 m)and alpine frost desert soil(4700-5000
m)。2.From south to north along the Yarlung Zangbo river valley, there are foursoil zones in
horizonal direction,namely latored yellow earth, yellow earth, yellowbrown earth and grey
brown earth,brown earth,According to the vertical spectrumof the Mt.Namjabarwa area,the soils
there might be grouped into five types。3.The influences of moisture degree,mountain altitude,
the inversion of tempe-rature and human activities on the vertical soil zones are also
discussed。
