摘要
近几年随着中国城市化的迅速发展，城市边缘区受到广泛的关注．但对城市边缘区的研究主要集中在城市边缘区的定性描述，而对边缘区的定量界定及增长驱动力研究较少．依据徐州市1987～2008年遥感图像，运用信息熵和异速增长模型对徐冲城市边缘区形成机制进行了研究．结果表明：徐州市边缘区扩张具有方向性，1987～2003年城市边缘区的扩张方向为东南方向，2003～2008年主要为北方向和西北方；基于异速增长模型人口的增长方向与城市边缘区的扩展方向基本吻合，说明人口是推动城市边缘区扩张的一个主导因素；在徐州城市边缘区扩张过程中，增加的城市用地主要来自于灌溉水田和林地，但在不同的阶段有所差异．
In recent years, with china＇s increasing urbanization, Urban Fringe has got extensive attention. However, the research is mainly about qualitative description of the Urban Fringe, while the quantitative determine and growth of driving force is less. In this paper, depending on remote sensing image of Xuzhou from 1987 to 200, the Information entropy model was used to analyze the growth of the Urban Fringe in Xuzhou city from 1987 to 2008. Fi- nally, the relationship of urban land use and population （1987 - 2008） is simulated by the allometric analysis method. Following results： Expansion of fringe zone in Xuzhou city has direction： from 1987 to 2003, the direction is south-east, but from 2003 to 2008, the direction is mainly northern and north-west. The increasing direction of population based on allometric growth model is similar to the city expansion direction, which proves that population is a main reason promoting the expansion of the Urban Fringe. During the expansion of urban fringe in Xuzhou city, the number of increasing urban land mainly comes from the paddy field and forest land, but varied in different stages
