Abstract:

In order to analyze the main causes of forest fires and casualties in China over the past 20 years,based on the case records of forest fire fighting casualties and statistical data on relevant meteorological factors(average temperature,average precipitation,average wind speed)from 2000 to 2022,statistical analysis and correlation analysis method were used to analyze the main causes of forest fire and the main causes of casualties in fire fighting.The results showed:1)From 2000 to 2022,a total of 134,671 forest fires occurred in China.Among these the period of high incidence of forest fires was from 2003 to 2010.Severe climatic conditions were the main cause of forest fires during that period.In the past 10 years,more than 97% of forest fires have been caused by humans.In regions such as Guangxi,Yunnan,and Guizhou where agriculture and forestry are closely integrated,forest fire accidents occur frequently.2)Analysis of typical forest fire fighting cases shows that the accidents resulting in direct casualties caused by geographical environment,combustible conditions,meteorological conditions and fire activities account for the dominant part,while the casualties caused by non-indirect causes such as asphyxia,accidents and improper operation of fire fighting equipment also occasionally occurred.The research shows that the main causes of forest fires in China are meteorological factors and human factors,with casualties primarily resulting from unfavorable natural conditions.The main causes of forest fires and the causes of casualties are elaborated to provide a reference for efficient firefighting,scientific and accurate command.
