| 摘 要： | 本文基于NPP-VIIRS夜光遥感数据对京津冀城市群2015—2019年的空间结构进行分析，通过灯光值统计、城市位序-规模法则、空间关联测度等方法探究京津冀城市群空间结构及时空变化特征，结合城市总体规划浅析时空变化的原因。结果表明：①京津冀城市群灯光总量整体呈上升趋势，北京市和天津市的灯光增长率最高，其次为河北省廊坊市和石家庄市。②灯光集中分布在高位序城市北京和天津，中小城市不够发达。从时间序列上看，中小型城市快速发展，京津冀各城市有趋于ZIPF理想状态分布的态势。③随着区域交通一体化的推进，城市间的关联度整体增强，北京市与天津市的总体关联度占主导地位，但北部城市与中南地区的交通联系不足，关联度较弱。

| Abstract: | This paper accesses NPP-VIIRS data to analyze the Beijing-Tianjin-Hebei urban agglomeration's spatial structure from 2015 to 2019, through data statistics, city rank-scale rule, spatial correlation intensity. Also, combined with the city master plan and other documents, discuss the temporal and spatial change. The results showed that: ①The total amount of nighttime light in the Beijing-Tianjin-Hebei urban agglomeration show an overall upward trend. Beijing and Tianjin had the highest lightning growth rates, followed by Langfang and Shijiazhuang. ②The lights are concentrated in the high-ranking cities Beijing and Tianjin. Small and medium-sized towns are underdeveloped. However, in terms of time series, small and medium-sized towns are developing rapidly, the lights of cities were tending towards ZIPF distribution. ③With the advancement of regional transportation integration, the degree of correlation between cities had generally increased. The overall connections between Beijing and Tianjin were dominant. The traffic connection between the northern towns and the central-southern regions is insufficient so that the correlation is weak. |
