Abstract: Towns grew slowly at the eastern fringe region of the Tibetan Plateau owing to the unique geographical environment and the restriction of multitudinous nationalities, cultures, religions and economy. The driving force of urban growth mainly root in the center administrative organizational system. For some towns, the super affinity of nationality culture, religion and trade plays important role. Urban growth is characterized by lower standard, small scale, indistinct function and differential spatial allocation. The unique nature-human geographical environment determines the urban growth and regional coordination. So it is necessary to select a regional urbanization model, which exhibits small scale, multiple levels, multiple centers and reasonable congregation. It is a good way to enhance the economic level through development of animal husbandry, electric power, metallurgical industry and building material industry. Towns of harmonious relationship between environment and social-economy should be developed through carrying out construction of eco-environment. Those towns are good for improving the human living circumstances. At last, it is suggested to improve the outer environment in order to help concerted development of urban and region.
