摘　　要：合肥,作为安徽省的首位城市,随着城市经济的发展和人口的快速增长,其城市建成区空间规模也随之不断扩大。本文利用1989年、1995年、1999年、2005年和2009年五期遥感信息图谱数据,借助GIS空间分析和相关统计方法,从建成区不同时期的面积变化、扩展强度以及空间分异特征三个方面对合肥市城市扩展的时空变化特征及驱动力进行了分析。研究结果表明:合肥市建成区面积在不断扩大中,空间变化形态主要经历了"团城状"形态——"风扇状"形态——单中心极核式形态——双中心多组团式形态——"141"形态五种形态。影响城市空间扩散速度的驱动力主要是经济与人口因素,而城市空间扩散形态的驱动力主要受自然条件、交通诱因和政策指导因素的影响。Hefei City is the capital of Anhui Province. Its constructed region is expanded continuously during its urbanization. The spatial expansion information and the driving forces of Hefei City were analyzed with the technology of GIS spatial analysis and statistical analysis from the aspects of area change, growth intensity and spatial temporal feature, based on the 1989, 1995, 1999, 2005 and 2009 Satellite Images. The results showed that the spatial variation of morphology of the built-up areas is like 'the circular city' form- the 'fan-shaped' form- a single center of polar nuclei form- the two-center multi-group form- '141' form. The main driving forces are economic and demographic factors which affect the speed of the spread of urban space. Natural conditions, transportation incentives and policy guidance are main driving forces affecting the proliferation of urban spatial form.
