| Abstract: | Mt. Namjabarwa, 7782 m above sea level, is situated at the eastern tip of the Himalaya Range. The regularities of soil geographic distribution in this area are summarized as follows: 1. The vertical zones of soil on the southern slope belong to a marine humid type, the vertical spectrum are composed of latored yellow earth (500-1100 m), yellow earth(1100-1900 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 difference in heat and moisture, the spectrum on the southern slope differs from that on the brown earth (2800-3200 m), podzol (3200-4200 m), grey-sod soil (4100-4500 m), 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 four soil zones in horizonal direction, namely latored yellow earth, yellow earth, yellow brown earth and grey brown earth, brown earth, According to the vertical spectrums of the Mt. Namjabarwa area, the soils there might be grouped into five types. 3. The influeces of moisture degree, mountain altitude, the inversion of temperature and human activities on the vertical soil zones are also discussed. |
