青藏高原东缘民族区域城镇可持续发展研究

Sustainable Development of Urban in the Eastern Fringe of the Tibetan Plateau

青藏高原东缘区域 ,由于独特的地理环境和多元民族、经济结构的制约 ,民族宗教文化、民族贸易的超常亲合及资源开发、人居环境的改善是城镇发展的主要动力 .低水平、小规模、职能分工不明确、空间分布差异大是城镇发展的主要特征 .严酷封闭的地理环境、落后的社会经济发展状态和脆弱的生态环境是主要的障碍因素 .因此选择“小规模、多中心、多层次、适当集中”的区域城镇化模式 ,强化城镇及区域特色产业 ,优化生态环境 ,营造城镇与区域协调发展的外部环境 。

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.
