摘要： 本研究基于时序VIIRS夜光影像，通过统计夜光总量，运用位序规模法则和首位度法，以及提取夜间点亮区域研究2012—2019年贵州省城市化发展。分析结果表明：贵州省所有城市的夜光总量均呈现增长态势，六盘水、黔西南和首位城市贵阳的夜光增长率远低于其他城市，遵义在夜光总量较大的基础上仍能在省内保持最高速增长；中小城市的发展活力优于大城市，城市结构分散，中心城市贵阳的集聚效应弱，没有充分发挥对其他城市的带动作用；随着次位城市(遵义市)呈现高增长态势，首位度逐渐降低，贵州省区域经济发展有两极增长的趋势。

Abstract: Using time-series VIIRS nighttime light imagery, this paper studies the urbanization development of Guizhou Province from 2012 to 2019 by measuring the total amount of nighttime light, using the rank scale rule and the law of the primate city as well as extracting the lighted area. The results show that the total amount of nighttime light in all cities of Guizhou Province shows a growth trend. In addition, the growth rates of nighttime light in Liupanshui, Qianxinan and Guiyang are far lower than other cities. Zunyi maintains the fastest growth in the province on the basis of large amount of light. The development vitality of small and mediumsized cities is better than that of the biggest city. The urban structure is scattered. The biggest city has weak agglomeration effect and does not fully play its leading role. With the high growth trend of the second city (Zunyi City), the law of the primate city is gradually decreasing, and Guizhou Province has a trend of bipolar growth.

Key words: nighttime light, remote sensing, urbanization, time series, VIIRS
