| 摘 要： | 本文利用多时相TM影像,基于GIS空间分析技术,运用缓冲区分析方法和因子分析方法,对成都市城市扩张及其驱动力进行了定量分析.结果表明:城市扩张在各缓冲带空间分异显著,城市扩张呈明显的“圈层式”扩展模式,总体上紧邻城市中心区域,具有较强的空间集中性,随城市中心到周边区域,空间集聚性减弱.城市扩张呈现不同的空间分异性；区域...

| Abstract: | Urban expansion and its driving forces in Chengdu city was quantitative analyzed by methods of buffer analysis and factors analysis based on TM data and GIS spatial analysis techniques in the paper.The result showed that urban spatial expansion within different buffer zones was obviously,the urban expansion mode was obvious circle-type,with strong spatial concentration close to the city centre area,and the spatial agglomeration weakened from the city center to the periphery area.The urban expansion presente... |
