Abstract:China is going through rapid urbanization. To understand the urban development status of Jiaxing, this paper made research on built-up areas extracted from remote sensing images, and took means of geographic information science and mathematical statistics to analyze the spatio-temporal characteristics of expansion process, as well as explored the driving factors based on the social and economic data. The research shows that the built-up areas in Jiaxing kept expanding from 1993 to 2013, with the rate and intensity changing from increasing to decreasing. The direction moved from the northwest to the south, and the expansion mode transformed from active to passive and then to stable. Urban construction is inconsistent with population. Driving factors of expansion are concluded as economic development, industrial restructuring and population growth.
