| Abstract: |
| With the increase of global warming, the frequency and intensity of global forest fire disasters
will also increase. The potential risk of forest fires around the world will exist for a long time and their severity
will also increase significantly. Forest fires have had a significant impact on forest ecological resources and the
global climate. Because of their sudden, destructive, and extremely difficult handling, it is one of the most serious
ecological disasters and sudden public events in the world. The law of forest fire occurrence and development
is an important basis for forest fire prevention and suppression. Strengthening the study of the law is conducive
to targeted forest fire prevention and extinguishment. Aiming at the current situation and development trend ofclimate change, combined with the status quo of forest fires at home and abroad in the context of climate change,
the effects of climate change on the occurrence and development of forest fires in China are systematically discussed. The climate affects the source of fire, the weather affects the behavior of forest fires, the climate determines the cycle of forest fires, and the impact of climate change on the spatial and temporal distribution of forest
fires. Under the background of global warming, we start with the analysis of the occurrence of forest fires in China. Through the study of the occurrence of forest fires in China under the background of climate change, we can
objectively understand the laws of forest fires in China and in various regions. The government effectively carries
out forest fire disaster prevention and emergency management, and effectively guarantees sustainable development of society and economy to provide scientific decision-making basis. |
