Abstract: Mt. Namjagbarwa, 7782 m above sea level, is situated at the southeastern Xizang Autonomous Region and the eastern tip of the Himalaya Range. Some problems of vertical zonation in this area have been discussed, in this paper, as follows:1. Based on the characteristics of the natural landscape, the basic belt of vertical zones on the southern slqpe is characterized by quasi-tropical monsoon rainforest yellowish lateritic red earth.2. According to the vertical speetra of the Mt. Namjagbarwa area the landscape there might be grouped into types, i.e. (1) quasi-tropical monsoon rainforest yellowish lateritic red earth; (2) mountain subtropical broad leaved evergreen forest mountain yellow earth; (3) mountain quasi-subtropical semi-evergreen broad leaved forest mountain yellow brown earth; (4) the mixed forest of mountain warm-temperate coniferous leaf and broad leaf mountain brown earth; (5) mountain frigid-temperate dark coniferous forest mountain alpine podzol.3. The influences of moisture passageway along the Yarlungzangbo Jiang river, ice and snow cover, the inversion of temperature on vertical natural zones are also described.
