摘要
以2000、2005、2009、2013年的Landsat遥感影像数据和相应年份的DMSP/OLS夜间灯光数据为基础,结合厦门市的社会经济数据,运用GIS和RS分析手段,通过引入紧凑度、城市重心、城市扩张速度、城市扩张强度、全域空间自相关系数、弹性系数等指标,对城市扩展过程中的时空特征、形态演变及其与经济发展之间的协调性进行测度.结果表明,厦门城市扩展空间形态变化呈现明显的阶段性,城市扩张过程中空间形态趋向稳定,土地开发利用和城市功能配置还处于较低水平.
In order to quantitatively measure the spatio-temporal characteristics and morphological e-volution of urban expansion in Xiamen City,some indexes such as compact ratio,center coordinate, urbanization speed index,urbanization intensive index,global spatial autocorrelation indices and elas-ticity coefficient were calculated by GIS and RS analysis methods. The relationship of urban built-up area and GDP in different periods was studied based on the remote sensing interpretation of Landsat images and the DMSP/ 0LS nighttime light images in 2000,2005,2009 and 2013. The results re-vealed that the rate of urban expansion in Xiamen City obviously changed from 2000 to 2013. In other words,the area of the existing districts had a slow growth rate from 2000 to 2005,a high - speed growth rate from 2005 to 2009,a rapid growth rate from 2009 to 2013. Generally, spatial patterns of urban expansion in Xiamen City tends to be stable, and land development and utilization of urban function allocation is still in a low level.
