新疆中心城市空间结构评价

Evaluation on Spatial Structure of the Central City in Xinjiang

随着经济的发展,城市的经济结构会随着产业结构的不断调整升级发生变化,同时城市的内部空间结构也会发生相应的变迁,这种变迁可以从一个侧面反映出该城市在当前阶段的发展水平和质量。通过建立城市空间结构评价体系,从经济效益、社会效益和环境效益三个方面,运用主成份分析法对新疆中心城市的城市空间结构进行了分析,并应用聚类分析进行了分类。结果表明新疆中心城市的城市空间结构差异较大,而且多数城市的空间结构发展不均衡,不够合理,最后在分析结果的基础上提出了一些改进的建议。

With the development of economy, the economic structure of a city would change with the con- stant adjustment and upgrading of industrial structure. It was same to the internal spatial structure of the cit- y. This change could reflect the level and quality of a city＇s development in the current stage from a side. Through establishing evaluation system of urban spatial structure, the paper analyzed the urban spatial structure of central cities of Xinjiang from three aspects of the economic, social and environmental benefits with the principal component analysis. Then the paper classified the central cities with cluster analysis. The results showed that ： the urban spatial structure of central cities of Xinjiang was quite different, and the urban spatial structure development was not balanced and reasonable to majority central cities. On the basis of analysis, some improvement suggestions were put forward.
