依据海拔高度把青藏地区单独划为一个区域,阐述其区域特征。已经表明了地形是影响本区地理环境形成的主导因素,地势高、气温低,于足,“地高天寒”就成为青藏地区主要的自然地理特征,一切地理要素都受到它的严重制约。例如:(1)气候、水文、植被、动物、资源等要素在它影响下都具有其独特性。(2)各地理要素之间相互影响、相互制约的辩证关系,表现的比其他区域明显,有助于人们对地理环境整体性和区域差异性的认识。(3)环境的“独特性”、“神秘性”带来科研、登山和旅游的“高价
According to the altitude, the Qinghai-Tibet region is divided into a single area and its regional characteristics are elaborated. It has been shown that the topography is the dominant factor influencing the formation of the geographical environment in the region. The terrain is high and the temperature is low. As a result, “high altitude and cold days” have become the main natural geographical features of the Qinghai-Tibet region, and all geographical factors are severely constrained by it. For example: (1) Climate, hydrology, vegetation, animals, resources and other elements all have their uniqueness under its influence. (2) The dialectical relationships that affect each other and restrict each other’s geographic elements are more obvious than other regions, which helps people to understand the overall geographical environment and regional differences. (3) The “uniqueness” and “mystery” of the environment have brought high prices for research, mountaineering, and tourism.
