| 摘 要： | 以山东省济南市为例，以1979—2005年5个不同时相的遥感图像为数据源，利用遥感信息提取技术，获取了城市扩展的空间信息。结合济南市社会经济统计数据，从扩展方向、重心转移等方面综合分析了济南市建成区扩展的时空特征，并从人口、经济、地理区位、政策导向等4个方面探讨了城市扩展的驱动力。结果表明，济南市城区扩展的整体趋势是东西向的带状扩张，向东扩张明显，城市重心向东北方向转移；1979年济南市城区面积是52．7km^2，2005年达到311．6km^2，是1979年的5．9倍。

| Abstract: | Taking Jinan as the example, the information of the buit-up area was extracted from Landsat TM (1979~2005) images. Combined with the current social economy data, this paper analyzed the characteristics of urban spatial-temporal change in Jinan city from the aspects of urban growth orientation and the urban gravity transfer model. The driving force of urban growth is also discussed form the view points of population, economy, geographical location and policy guidance,etc.. Results show that the whole trend o... |
