摘要: 城市化、社会经济发展和资源环境系统之间的协调机制是学术界关注的焦点议题。夜间灯光(nighttime light,NTL)数据与人类的生产和生活足迹密切相关,在人口密集的城市化地区的研究及相关数据挖掘方面有明显优势。基于中国知网(CNKI)与Web of Science (WOS)核心合集数据库,利用CiteSpace文献计量软件,梳理NTL数据在城市化及其资源环境效应研究中的热点主题。结果表明:1)城市化这一主题是NTL数据相关的中、英文文献共同关注的核心主题,但在城市化引致的资源环境效应方面的研究仍有待于拓展;2)城市用地提取和城市空间结构的研究,集中在基于不同NTL特征表征土地城市化进程,而在人口和社会经济发展、电力消费和碳排放的研究中,NTL数据通常作为辅助数据用于探究更精细尺度上的时空特征、影响因素以及作用机制;3)在大气污染和城市热岛效应相关研究中,NTL通常被用来表征城市化、社会经济发展、人类活动因子,进而用于不同因子对空气污染和城市热岛效应的作用机制研究;4)城市化、社会经济发展与资源环境效应表现出复杂的交互作用,数据空间分辨率的提高、多源数据的综合利用以及复杂模型方法的使用等,使研究得以深化。最后,从数据融合、主题拓展、方法创新等3个方面,总结分析NTL数据相关研究未来可能的新方向与侧重点。

Abstract: Being closely related to human socioeconomic activity and its footprints, nighttime light (NTL) data shows great advantages in urbanization and socioeconomic development research, especially in densely populated cities. Based on CiteSpace software and the core databases of CNKI (China National Knowledge Infrastructure) and WOS (Web of Science), this paper tracked the hot spots of NTL data in the study of urbanization and related resource consumption and environmental effects from 2000 to 2019. The main results are as follows. 1) Urbanization was the main focus of the application of NTL data, but the researches on the resource consumption and environmental effects caused by urbanization were slightly weak, which was more obvious in Chinese literature. 2) Researches of urban expansion and urban form evolution focused on process of land expansion based on different features of NTL datasets, while in researches of population, socioeconomic development, electricity consumption and carbon emissions, NTL data usually played the role as a supporting tool to explore spatiotemporal characteristics and mechanism. 3) In regards of air pollution and urban heat island induced by urbanization, NTL datasets were usually used to represent factors related to human activities and their impacts. 4) Urbanization process and its impacts on resource and environment are complex, the improved spatial resolution and integrated multi-source data, along with new methods as machine learning, will make the urbanization related research be more precise and scientific. Finally, the paper summarizes the possible new directions of the application of NTL data in urban geography.

Key words: nighttime light data, bibliometric analysis, resource and environmental effects, urbanization
