21世纪前期青藏高原交通运输网络发展前景探讨

作为世界第三极和中国第一大自然阶梯 ,青藏高原自然条件及其环境较差 ,高寒缺氧、位置偏远、地广人稀是其基本特征。高原的现代交通运输 (包括公路、铁路、航空和管道 4种运输方式 )开始建设和发展于 2 0世纪 5 0年代 ,目前运输网络已初步形成 ,但其规模和结构依然比较落后。进入 2 1世纪后 ,随着西部大开发战略的实施 ,中央和相关省市支持力度的提升和加强 ,高原的现代交通运输及其网络将会进一步加快发展 ,尤其是铁路和航空运输线路、设施的建设与其产业的发展

DEVELOPMENT PROSPECT OF COMMUNICATION AND TRANSPORTATION NETWORKS OF THE QINGHAI-TIBET PLATEAU IN THE EARLIER STAGE OF 21ST CENTURY

The Qinghai-Tibet Plateau, known as the world third polar and the highest terrain of China, has relatively poor natural conditions, essential features of which are cold affected zone with lacking oxygen, remote location with a small population in extensive area. The construction of modern communication and transportation network within the Qinghai-Tibet Plateau, consisting of 4 transport modes as highway, railway, airline and pipeline, has been launched out in 1950s. So far the modern transportation network has been initially formed, but regarding the scale and structure, it is still relatively laggard. It is estimated that the modern communication and transportation network of the Qinghai-Tibet Plateau will be greatly accelerated after entering the 21 st century, owing to the implementation of the Strategy of Western China Development, as well as the enhanced supports from both the central government and relevant provinces and cities.
