摘要
以不同时相的TM图像为主要数据源,基于遥感原理和技术,利用图像处理软件,揭示城市土地利用扩展的空间分异规律,对徐州市建成区扩展的动态变化数据进行了监测;并结合与城市发展相关的历史文献资料、城市统计资料,对徐州历史时期以及1987年以来城市建成区扩展的时空变化进行了系统分析和总结,并讨论了影响城市建成区变化的驱动力的主要因素。
Choosing urban constructed area as the indicator for the urban development level, using multi-temporal Landsat TM images as data sources, this paper exposes the spatial differentiation of Xuzhou urban constructed area. In addition, analyzing some concerned historical literatures, urban statistic data, this paper provides a deftnite illustration of the spatial pattern and growth rates of changes resulting from urban development. As many factors have contributed to the urban land use changes, three major driving forces are discussed： economic development, population growth and transportation development.
