Abstract:

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.
