Using GIS for analysis of urban systems
Abstract:It is recognized that the spatial organization of urban system can be abstracted as three main components: a set of points, which describes the structural characteristics such as social and economic properties of individual city; a set of lines, which indicates the patterns of interaction among the cities; a set of spheres, which indicates how and to which extent each city affects the area around it. Even if such substance of urban system coincides with the main purpose of GIS for spatial or geometric data types such as point, line and region, little attention has been given to this point. By an evidence analysis of China, the application of potential analytical capabilities of GIS for urban system is attempted in this study. We find GIS acts as an efficient tool not only for the spatial structure analysis of urban system, which including potential distribution of cities, extraction of principal linkages among cities, and delimitation of subsystems; but also for the verification of socio-economic attributes and dynamics of urban system.
