Abstract: In order to improve risk management of forest fire in Beijing-Tianjin-Hebei region, based on public safety triangle theory, a total of 14 indicators in three categories were obtained and processed through Remote Sensing and Geography Information System (GIS). Then, their weights were determined by entropy weighting method, and comprehensive forest fire risk of the region was calculated and analyzed by utilizing GIS. Finally, this evaluation method was verified by comparing assessment results with historical fire data. The results show that major influencing factor for hazard is density of residential areas, that is vegetation coverage for target sensitivity, per capita GDP for target exposedness and fire force development for rescue capability. It is also found that comprehensive risk of forest fire has been decreasing from 2005 to 2015 in Beijing-Tianjin-Hebei region.

Key words: Beijing-Tianjin-Hebei, forest fire, comprehensive risk assessment, public safety triangle, entropy weighting method
