基于知识图谱的夜光遥感研究热点前沿分析
Analysis of Research Hotspots and Frontier in Nighttime Remote Sensing Based on Knowledge Mapping
摘要
Abstract
To explore the research hotspots and development trends in nighttime remote sensing over the past 30 years,a bibliometric analysis was conducted using CiteSpace software on core literature indexed in the WOS database,as well as journals from the Peking University Core and CSCD databases in CNKI,spanning from 1990 to 2024.The results show that:1)Nighttime remote sensing research has gone through the"initial stage""slow accumulation stage"and"rapid development stage",exhibiting a trend of gradual growth followed by rap-id development.2)There are close connections between various research institutions and collaborators,with domestic and international author collaborations displaying a cluster distribution,which underscores diverse research directions in nighttime remote sensing at different time periods.3)Keyword clustering analysis found that Chinese literature clusters mainly focus on human activities,population distribution,and impact mechanisms,while English literature clusters highlight three major characteristics of nighttime remote sensing research:"data processing and analysis""innovation in technologies and methods"and"multi-scale and multi-temporal analysis".4)Keyword burst analysis and co-occurrence maps from the past three years reveal the frequent appearance of the keyword"Machine learning"and the emergence of the independent node for"SDGSAT-1",which are continu-ously driving technological innovation and breakthroughs in data applications for nighttime remote sensing.关键词
