摘　　要：该文以东莞市为例,针对其缺乏较长跨度、较为系统的城市扩张问题,提出了用多期TM和SPOT遥感影像监测和分析1988—2013年城市扩张的动态变化和扩张强度。该文采用相关性检验和主成分分析等方法建立逐步回归模型,对城市扩张进行了驱动机制分析。研究表明,所提方法定量分析了城市扩张的数量变化、扩张强度和4个不同阶段,研究成果可以为土地资源管理和城市规划提供科学参考。Taking Dongguan city as an example, this paper puts forward the dynamic change and expansion intensity of urban expansion from 1988 to 2013 with TM and spot remote sensing images in view of its lack of longer span and more systematie urban expansion. By using correlation test and principal compo- nent analysis, this paper establishes a stepwise regression model and analyses the driving mechanism of urban expansion. The research shows that the proposed method quantitative analysis of the number of urban expansion, expansion intensity and four different stages, the research results can provide scientific reference for land resource management and urban planning.
