Abstract The measurement and calculation of urban spatial information is the basic work of map-based graphical analysis, as well as one basic function of the spatial analysis in the Urban Geographic Information Systems (UGIS). Spatial analysis includes the measurement and calculation of the geometric parameters of linear and planar objectives. The measurement and calculation of urban spatial information, which is based on UGIS, not only describe the features of the city's shape quantitatively, but also facilitate to understand the law and mechanism of the urban spatial phenomenon and spatial processes so that the phenomenon of urban space and spatial process can be forecasted to control and make decision on the urban space processes. Based on the UGIS platform of space geometry calculation, this paper explores the spatial characteristics of Guangzhou Administrative Region. It is demonstrated that the city is separately and isolatedly structured. It stretches to the north and south but the two ends are hardly connected so the space is not fully utilized and the districts do not cooperate each other well. These factors including the landform, traffic net and population distribution of Guangzhou city all reveal the increasingly obvious tendency of the city's development that the city keeps expanding and tightening its links with its surrounding areas. The "greater" Guangzhou is being formed, based on the newly developed metropolitan residential and other functional districts on the combined lands of Guangzhou City and its neighboring areas, which have been all tightly linked by the highways of Guanshen and Guangzhu. This study will promote the theoretical research on urban morphology studies in China, and enrich the empirical study of the city spatial form as well.
