西藏地广人稀,地形地质复杂,高寒缺氧。解放前,全区没有现代意义的公路,运输全靠人背畜驮,交通闭塞。和平解放后,特别是党的十一届三中全会以来,在党和国家的亲切关怀和全国人民的大力支援下,经过全区各级党委、政府和各族人民及驻藏人民解放军的共同努力,西藏交通事业发生了翻天覆地的变化,取得了巨大的成就,基本形成了以公路运输为主,以航空、管道运输为辅的现代运输新格局。 Tibet sparsely populated, terrain complex, alpine hypoxia. Before the liberation, there was no road of modern significance in the whole district, and transportation was totally dependent on people carrying animals and traffic was blocked. After the peaceful liberation, especially since the Third Plenary Session of the Eleventh Central Committee of the Party, with the cordial care of the party and the country and the vigorous support of the people throughout the country, the commonalities of the party committees, governments, people of all nationalities and the People’s Liberation Army stationed in Tibet throughout the region Efforts to make tremendous changes have taken place in transportation in Tibet have made great achievements and basically formed a new pattern of modern transport dominated by road transport and supplemented by air and pipeline transportation.
