Abstract: Abstract: In review of the collected data on fire and rescue in Guangdong Province between 2016 to 2021, this research studied statistical change trend, characteristics of regional distribution, various category distribution, and the distribution of alarm time. An analysis model was developed using spatial analysis method. Based on 3 factors, including the current urban construction land usage, data on fire and rescue frequencies and urban development?boundary, analysis on the optimizing of fire and rescue station planning layout was conducted, which provides valuable statistical evidence to support the development of the designated fire and rescue station.
