摘　　要：本文利用多时段TM影像图和城市规划图,采用GIS空间分析技术,运用象限方位分析方法对徐州市城市空间扩展强度、重心坐标等指数进行定量分析,生成交通建设与城市规模的相关系数矩阵,研究该市城市空间扩展与交通脉动的变化规律。结果表明:1979—2008年间,受城区主干道路、高速公路、高速铁路等重大交通设施建设影响,徐州市城市规模逐步向东部和南部扩散,城市重心总体向东南方向偏移;紧凑度逐渐减小,分形维数逐渐增大,城市空间形态日益复杂。Based on the TM images and urban planning images, the authors made rational analysis on Xuzhou city spatial expansion from the aspects of growth intensity, center coordinates and other indexes by means of quadrant analysis built in GIS spatial analysis techniques. Then the authors made correlation coefficient matrix among urban spatial expansion and traffic pulsing and found out the changing laws among the factors. The results showed that during the year 1979 and 2008, the city expanded towards the east and the south and the city center moved towards southeast gradually influenced by the urban main streets, expressway, high-speed railway and uther significant traffic constructions. The urban compact index was decreasing and the fractal index was increasing. The urban structure became more and more complex.
