乌鲁木齐集聚扩散的空间分析

城市的集聚扩散涉及政治、经济、文化、科技、信息等，其中实质性的是经济的集聚和扩散。集聚扩散的强度与距中心城市的远近有关，距离越远，强度越小。集聚扩散的方式主要通过人口流、物质流、信息流、技术流来实现。基于大量的调查资料，采用定量、定性相结合的方法，对乌鲁木齐的空间集聚扩散的范围和强度做具体的分析和探讨。

SPATIAL ANALYSIS OF AGGLOMERATION AND DIFFUSION IN URUMQI

Urban agglomeration and diffusion include many aspects, such as politics, economy, culture, science, technology and information, the essence of which is economic agglomeration and diffusion. The distance to the core city affects intensity of agglomeration and diffusion. The farther the distance between core city and around cities, the less intimate the intensity is. This paper investigates and gathers plenty of materials, uses quantitative and qualitative analysis methods togather to research intensity and range of special agglomeration and diffusion in Urumqi. The target system includes four sub systems: flow of population, substance, information and technology, and eight indexes: times of passenger road transport, quantity of passenger road transport in regions, quantity of passenger railway transport, density of freight railway transport, sales volume and sales frequency of small commodities in Xinjiang Shangmao market city, publishing quantity of Xinjiang Daily, coordinated items of economy and technology between Urumqi and other cities and counties. After having synthetic evaluation, following conclusions can be gotten in the paper: In range of the whole Xinjiang, the intensity of agglomeration and diffusion can be divided obviously into five grades. Miquan, Changji, Karamayi, Turpan, Hutubi, Shihezi and Fukang are the strongest areas of agglomeration and diffusion with Urumqi. These regions, where there is a stronger relationship with Urumqi, are Korla, Yining, Hami, Bole, Wusu, Kuitun, Wujiaqu and Aksu. The regions located in the middle range of agglomeration and diffusion of Urumqi are Shanshan, Kuqa, Shawan. Most of the counties are located in the weak range of agglomeration and diffusion of Urumqi. The counties in border land are located in the weakest range of agglomeration and diffusion of Urumqi.
