Abstract It is concerned that China has experienced a rapid economic growth process, accelerated urbanization and industrialization, gradually increasing the level of urbanization since the reform and opening up. This paper takes the urban expansion during 1982 to 2008 of Guangzhou-Foshan metropolitan area as a study case. In order to measure and analysis the urban expansion in Guangzhou-Foshan metropolitan area, the normalized thematic data of urban construction land and road network were extracted by using RS and GIS methods, from topographic maps of 1982, remote sensing images acquired in 1995 and 2008. The spatial data were stored in database. Various GIS spatial analysis methods are used here to qualitative and quantitative analysis of the urban expansion in Guangzhou-Foshan metropolitan area, including overlay, interpolation, distance analysis, etc. At the same time, it will be measured and analyzed from three aspects like strength of the expansion, the expansion mode and extended efficiency.The application result indicates that the expansion of urban construction land in Guangzhou-Foshan metropolitan area shows the characteristics of powerful and fast since the reform and opening. However, the development and utilization of land is not reasonable, and the space expansion is not very efficient. The study area has a certain discontinuous development phenomena and significantly development characteristics along the road network, which reflects the typical sprawling development patterns: randomly expansion at central district fringe, strip development along road network, scattered land development. The expansion features of high-speed, inefficient and disorderly in Guangzhou-Foshan metropolitan area indicate that there may be a tendency to sprawl in the process of its rapid development.
