The distribution of urban living space in Lanzhou and their causes analysis

城市居住空间是城市空间的重要组成部分。兰州市是典型的河谷型城市,对其居住空间进行研究,有助于揭示该类城市居住空间分布规律,合理引导城市居住空间的发展,优化城市居住空间结构。基于统计资料并结合实地调查,运用Arcgis软件的空间分析功能,从定量分析角度揭示出兰州市居住空间呈现沿交通线集聚分布、区域布局不均衡以及居住空间分异现象初显的特点。并从自然地理环境、城市规划、住房制度、房地产业的发展以及交通建设方面分析了兰州市居住空间分布形成的原因。

Urban living space is one of the main content of the urban space.With the deepening of the housing system reform in China,the residential spatial structure has gradually assumed a complex shape along with its tremendous changes in valley-city.Lanzhou city is a typical valley-city.It is crucial and necessary to show the Lanzhou＇s living space in order to guide the valley-city＇s housing development and optimize the urban living space structure.Based on the statistical data and the investigation,this paper ties to open up the living space distribution rule of Lanzhou city from the quantitative analysis of angle by means of Arcgis software space analysis function.As far as living space structure is concerned,the three characteristics of living space distribution are identified： ① The living space along the city traffic line concentration distribution;② The regional layout disequilibrium;③ The residential space differentiation phenomenon previews of characteristics.At last Lanzhou city living space distribution formation reasons was researched from the natural geographical environment,urban planning,housing system,the development of real estate and traffic construction.
