摘　　要：定量研究城市外部空间形态是城市建设与规划的重要环节。文章应用分形原理和方法以及GIS技术定量研究了无规则、具有自相似性的城市外部空间形态,以武汉市为例分析了多核心组团式城市空间形态分形特征,以及武汉市50年间的分维演变规律,并分析了不同阶段城市分维值变化的原因以及城市扩展的方式,最后提出采用多理论、多技术手段综合集成的方法是未来深入研究城市空间形态的重要途径。Quantitative research urban outer spatial form is importance tache of urban constructing and planning. An urban outer spatial form characteristic, which has no-rule and having self-similarity, is researched by means of fractal theory based on GIS, taking Wuhan city for example, the fractal characteristic of multi-core and group urban spatial form is analyzed, and the evolutive rule of the fractal dimension during 50 years in Wuhan city is researched, and the reason of the fractal dimension's change in different stages and the mode of urban expansion is discussed, and finally, the view-point is put forward that it is the important approach in the future to integrate multi-theory, multi-technique method to research urban spatial form deeply.
