This study applies CiteSpace software to analyze
the research data related to remote sensing field of burned area, draw the
knowledge map, sort out the research hotspots and evolution history at home and
abroad, explore the research difficulties, and provide possible research
directions for later researchers. In this paper, the literatures were collected
in the core database of the Web of Science from 2000 to 2020 as a research
sample, and conducted co-authorship feature analysis, keyword co-occurrence
analysis and literature co-citation analysis. The results are as follows: The
most active countries, institutions and authors are the United States, the
University of Maryland and JOANNE C WHITE, respectively. According to the
evolution process of keywords, it can be divided into three stages. North America,
Landsat, protected areas are the research hotspots, and will maintain highly
active in the future. The future research trends of fire information extraction
research mainly show in three aspects: improving the accuracy of fire
monitoring, expanding research field and expanding the application range of
existing fire products.
