摘　　要：以武汉市为研究对象,基于武汉多时相航摄影像数据,借助GIS技术和空间分析方法,以城市用地扩展速度和强度指数、分形维数、紧凑度为城市形态指标,实证分析1986～2008年间武汉城市建成区外部形状的变化过程,期望为武汉规划决策的制定以及相关调控措施的研究等提供依据。Taking Wuhan city as research object,based on multi-temporal aerial photogrammetric data in Wuhan,supported by GIS technology and spatial analysis method,this paper analyzed the change process of exterior form of built-up area in Wuhan city from 1986 to 2008 with the urban spatial form parameters,such as urban land expansion speed and intensity,fractal dimension and compactness,etc.It is expected to provide reference for the establishment of planning strategy and the research on related adjustable measurement.
