摘要
在研究城市化进程时,基于DMSP/OLS夜间灯光数据获得的城市空间信息基本可以反映我国城市化发展的实际情况。以河南省为例,提取出2000-2012年的河南城市化空间信息,对河南省18个市级行政区的城市化空间扩张进行监测,分析城市空间扩张的格局变化及速率,得出影响城市空间扩张的因素并预测城市空间扩张的方向。
In the process of urbanization, the urban spatial information obtained by DMSP/OLS night lightdata can reflect the actual situation of China＇s urbanization development. Taking Henan Province as an ex-ample, this paper extracted Henan urban spatial information in 2000-2012, and monitored the urban spatialexpansion of the 18 municipal administrative regions in Henan Province, the urban spatial expansion of thepattern of change and rate was analyzed, the factors that affect the expansion of urban space and the direc-tion of the expansion of urban space were obtained.
