南迦巴瓦峰与托木尔峰山地垂直自然带的比较

南迦巴瓦峰地处喜马拉雅山脉东端雅鲁藏布江大拐弯的内侧，托木尔峰地处天山山脉的西端，二者独特的自然地理特征及其高大的山体为山地垂直自然带谱的形成和发展提从了十分有利的自然环境，发育了相当完整的山地垂直系列。比较二者的垂直带谱，可以发现无论在垂直带谱的形成条件，基带，性质和结构类型，还是景观特征，垂直分异影响因素及南北坡差异程度等方面，都存在着较大的差异。南峰垂直带谱为以森林－草原－荒漠土壤系列为特征的季风性湿润，法湿润带谱系统，垂直分异的主导因素为温度；托峰垂直带谱为以荒漠－－草原－荒漠土壤系列为特征的大陆性干旱带谱系统，垂直分异的主导因素为湿度。不同的垂直自然带特征决定了不同的资源开发利用和保护措施。

Comparison of the Natural Vertical Zones Between Mt. Namjagbarwa and Mt. Tomur

Mt.Namjagbarwa is situated in the east end of Himalayas and near the big turn of Yaluzangzu River with an altitude of 7782m and favourable natural condition and relative huge altitude difference on its southern slope where a fairly complete tropical mountainous vertical zone series is formed.The basal zone of the southern slope is the quasi-tropical monsoon forest zone.Mt.Tomur,the highest peak of the Tienshan Mountain,rises 7435.3m above sea level and is situated at the western end of the Tienshan Mountain of China.A relatively complete natural vertical zone series is also formed with temperate zone as its basal zone in the area. There exists obvious spatial difference in natural vertical zones of Mt.Namjagbarwa in comparison with that of Mt.Tomur.These differences can be found either in formation,structure composition of the natural vertical zones,the basal zones,the composition of zones or in landscape characteristic,discrepancy degree between the southern and northern slopes and predominate differential factor and so on.The result of the study shows that the former is characteristic of forest-grassland-desert soil zone series,which belongs to the humid and semi-humid spectral system pattern of monsoon while the latteris characteristic of desert-grassland-desert soil zone series,which belongs to the humid and semi-humid spectral system pattern of monsoon while the latter is characteristic of desert-grassland-desert soil zone series,which belongs to the humid and semi-humid spectral system pattern of monsoon while the latter is characteristic of desert-grassland-forest(northern slope)-desert soil zone series,which belongs to the arid spectral sysytem comtinental pattern.Different ways of resource exploitation and environmental protection also discussed in accordance with natural vertical zones.
