Abstract: The Arctic region mainly includes the Arctic Ocean and the surrounding treeless tundra. The vegetation is mainly low shrubs, grasses, herbs, moss and lichens growing close to the ground. The climate is cold all year round, and the source of fire is mainly dry thunderstorms. Affected by global warming and heat waves, the number and intensity of wildfires in the Arctic region are increasing, posing a serious threat to ecological security and causing a series of secondary disasters. On the basis of summarizing the cases of mountain fires in the Arctic region in 2019 and 2020, this paper analyzes the causes and hazards of mountain fires in the Arctic region, and puts forward the enlightenment for forest fore management in alpine regions in China based on years of forest fire control experience.
