DEVELOPMENT OF COMMUNICATION AND TRANSPORTATION IN THE SOUTHERN VALLEY OF THE QINGHAI-TIBET PLATEAU
青藏高原藏南谷地的交通运输发展

The southern valley of the Tibet Autonomous Region is one of the key areas for sustainable development.It is also the core area with relative concentrated population and relative developing socioeconomy in the region. Although the region's modern communication and transportation network has preliminarily taken shape, yet it is still at lower development level with irrational structure and low input\|output. Hence the development trend and strategies of the region's future communication and transportation aspect will continue to maintain the existing communication and transportation framework for a long period of time, to likely go on improving the quality and grade of the highways, to increase step by step transportation capacity of the finished oil pipelines, and to speed up development of airline transportation and continued construction of Qinghai\|Tibet railway. In addition, the construction and maintenance of the entire transportation and communication system needs continuous support and input from central government without direct economic returns.
