Abstract

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.

Key words: Beijing-Tianjin-Hebei urban agglomeration, nighttime light remote sensing, spatial structure change, city rank-scale rule, spatial correlation
