摘　　要：城市空间的增长不仅仅表现在城市用地的扩张,还表现在城市功能用地的演替。城市功能用地的演替可以更加深刻地揭示城市空间外延式水平扩展的内在特征,是城市功能集聚与扩散的空间反映。以长春市中心城区为例,利用2003、2007、2010、2012年4个年份的遥感影像图、地形图及城市用地现状图等数据资源,借助Arc GIS、Auto CAD等软件,运用GIS分析方法,在分析中心城区城市空间扩展的总体格局及城市用地结构变化的基础上,提出以外部扩展与内部更替来表达城市功能用地的演替,进而阐释城市空间扩展及城市功能集聚与扩散的内在特征,为城市空间扩展的研究提供一种新的、有效的手段,以丰富城市空间研究的理论成果体系。The growth of urban space occurs not only through urban land expansion, but also from the transition of urban functional land. The transition of urban functional land can profoundly reveal the internal features of horizontal expansion of urban space, and is the spatial reflection of urban functional agglomeration and diffusion. The paper takes the central city of Changchun as a case study. ArcGIS, AutoCAD and GIS analysis methods are used in the article. Based on remote sensing images, topographic maps and land use maps covering the years of 2003, 2007, 2010 and 2012, the study analyzes the external expansion and internal renewal of urban functional land. First, the paper analyzes the overall pattem of urban spatial expansion and the change of urban land structure. Second, the external expansion and intemal renewal of urban functional land are used to express the transition of urban functional land. Finally, the paper explains the intemal features of urban spatial expansion and urban functional agglomeration and diffusion. The goal of this work is to provide a new and effective way to study urban spatial expansion, enriching the theoretical foundation of urban space studies. The research reveals the following points： （1） Overall, a continuous urban sprawl is still the main mode of urban spatial expansion. （2） The direction of urban spatial expansion of Changchun has phased characteristics. （3） Residential land and industrial land are the major urban functional land types in Changchun. （4） Examining three study periods reveals that external expansion and internal renewal occur in different time intervals. （5） Internal renewal and external expansion of urban functional land are important indicators of urban spatial expansion.
