| 摘 要： | 通过对实地调研和大量文献分析,对我国西北干旱地区城市发展与自然环境的关系进行论述,认为城市化过程本质上就是人地关系的集中凸现,是自然要素与人文要素长期互相作用的结果。自古以来,城市就是人类聚居的主要场所,屯垦是西北干旱地区最能体现人地关系的耦合点。在西北干旱地区现代城市化过程中,屯垦和矿产资源开发有较大的带动作用。由于自然因素和社会因素的双重影响,人口分布和聚居程度极不均衡,社会经济分异较大,城镇功能单一,部分地区和城镇的人口城镇化水平较高,并不是社会经济整体发展的结果,而是资源开采、行政建制的设立、极端自然条件下生存的需要等多种因素形成的。城市分布空间格局以带状、团状、串珠状为主,有着不同于其他地区的演化模式,城镇发展表现出多元复合的特征,是政治、经济、生态环境、资源、民族与文化等诸多因素相互关联、起伏变化的结果。城镇高速发展、城市化速度加快是未来西北干旱地区社会经济发展的必然结果,面对脆弱的生态环境和有限的资源,提出在西北干旱地区建设只有城镇、没有村落的新型城市社会,以达到社会经济和生态环境可持续发展的目标。

| Abstract: | By the field surveying and analyzing a great deal of literature and discussing the relation between urban development and natural environment, it was thought that urbanization essentially was the concentrative exhibition of the relation between human and environment, it was the nature and humanities factors'long -term interactional result. From of old, city was human's main settlement, the station troops to open up wasteland was the coupling site that can embody the relation between human and environment most. The station troops to open up wasteland and exploration of mineral resources had the biggish leading effect to modem urbanization of northwest arid area, because of the double effect of nature and humanities factors, the population distributing and settlement degree were seriously lopsided, social economy differentiation was biggish, the urbanization level of resource industrial city and agriculture and animal husbandry city were rugged, functions of the town were single, the population's urbanization level of some region and town was relatively high, it didnt result from whole social economic development, it resulted from multi-factor such as resource exploration, organic administration instauration, the existent demand under extreme natural condition. The spatial patterns of city distributing mainly were zonal, round and a string of beads, had the evolvement pattern different from other areas, the development of town put up multi-factor complex character, it resulted from politics, economy, eco-environment, resource, nation and culture, multi-factors'mutual relating and fluctuant change. Town's high-speed development and acceleration of urbanization will be the certain result of social economic development in northwest arid area in the future. Facing on the flimsy eco-environment and limited resource, it was brought forward that it should build the new-style society without town and village to reach the target that social economy and eco-environment have sustainable development. |
