Abstract: Based on the data of DMSP/OLS and NPP/VIIRS nighttime light data, and combined with the socio-economic statistics, the spatial pattern of urban space in Henan Province was analyzed through the extraction of the built-up area. At the same time, the theoretical model of the center of gravity was introduced to identify the economy, population and light center of gravity trajectory evolution, in order to compare the analysis of urban space expansion. The findings can be summarized as follows:①The urbanization process of northern city cluster which take Zhengzhou as the core is fast, the spatial expansion relationship between Zhengzhou and Kaifeng closely. ②The development level of east - west in Henan Province is higher than that in north - south direction, the central plain area develops better than the southwest mountain city, and the overall expansion is concentrated. ③Light center of gravity mainly transfer to the northeast, consistent with the direction of economic focus shifted, while the direction of the center of gravity shift significantly deviated. ④Good correlation exists between night light intensity and built-up area. At the same time, the correlation between economic development and nighttime light intensity & built-up area is higher than that between population and nighttime light intensity & built-up area.
摘要: 利用DMSP/OLS和NPP/VIIRS夜间灯光数据,结合社会经济统计数据,分析了河南省城市建成区空间格局的变化;通过引入重心理论模型,识别了河南省经济、人口、灯光重心轨迹演变。结果表明:①以郑州为核心的中北部城市群,城市化进程较快,郑州和开封的空间扩展联系紧密;河南省东西向建成区扩展水平高于南北方向,中部平原区好于西南部山区,整体呈现集聚式扩张;②灯光重心主要向东北方向移动,与经济重心转移方向一致,与人口重心方向明显偏离。③夜间灯光强度与建成区面积相关性较高,经济发展情况与夜间灯光强度以及建成区面积的相关性均高于人口与灯光及建成区面积的相关性。
