| 摘 要： | 西藏昌都地区的地域分异受多种因素的影响。就中尺度范围而言,不同等级谷地垂直自然带、多级自然地理面和地形组合引起的地域分异显著,并导致土地利用类型的差别。从小尺度范围来看,坡向不同、坡度陡缓和岩性差别引起的地域分异亦明显,并影响着不同的土地利用方式。

| Abstract: | This paper deals with regional differentiation in Qamdo District,eastern Xizang. The aim is to recognize the regional distributional pattern in meso- and micro-scale through identification of relevant elements.Qamdo District is located in the eastern Xizang,northwestern part of Hengduan Mountains. It covers parts of middle and upper reaches of the Nujiang,Lancang and Jinsha Rivers. It is in the transition zone from high plateau to 'deep gorges.Meso-scaled elements of regional differentiation comprise valley grade,physico-geographic surface and landform,which influence distributional range and characters of vertical belts. They are indicators to identify land-use types. Micro-scaled elements of regional differentiation include orientation of slope, gradient of slope and type of parent material which affect distributional characters within vertical belt. They are indicators to distinguish varied manner degree of land--use. |
