At present, urbanization of China is in an acceleration stage. Urban sprawl exists in majority cities, which has serious destruction of ecological environment in urban fringe. Firstly, by means of GIS and RS technology ,we analyze spatial-temporal features and discipline of urban sprawl based on remote sensing images of Changchun, the compact ratio, fragmentation degree, the degree of shaft extension, geometric center of gravity and so on. In addition, combined with relevant statistical information, we analyze the coordination of urban sprawl and social economy.Finally, we consider that construction of large-scale projects, development of real estate in suburbs, motorization and construction of traffic facilities, the role of government administrative decisions, and the runaway urban planning, have contributed to the urban sprawl of Changchun.
