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.

关 键 词:夜间灯光数据  城市扩展  遥感  厦门市

Abstract:In order to quantitatively measure the spatio-temporal characteristics and morphological evolution of urban expansion in Xiamen City, some indexes such as compact ratio, centre coordinate, urbanization speed index, urbanization intensive index, global spatial autocorrelation indices and elasticity 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/OLS nighttime light images in 2000, 2005, 2009 and 2013. The results revealed that the rate of urban expansion in Xiamen City obviously changed from 2000 to 2013, or 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 tend to be stable, and land development and utilization of urban function allocation is still in a low level. The relationship between urban expansion and economic growth in Xiamen is reasonable. However, the promoting effect of economic growth to urban expansion starts to slow down in recent years. Urban land use tends to intensive so that the urban land economic benefits have been improved. Based on the results of the research and the guiding ideology of the new urbanization development in China, some suggestions are put forward for the land expansion and economic coordinated development in Xiamen City.
Keywords:Nighttime lighting data  Urban spatial expansion  Remote sensing  Xiamen
