摘要
北极地区主要包括北冰洋和周围一圈无树木的冻土地带,植被以生长接近地面的低矮灌木、类禾本植物、草本植物、苔藓和地衣为主,气候终年寒冷,火源以干雷暴为主。受全球变暖和高温热浪影响,北极地区山火的数量和强度不断增加,严重威胁生态安全,并引发一系列次生灾害。本文在总结2019年和2020年北极地区山火案例的基础上,分析北极地区山火成因和危害,结合多年森林消防工作经验,提出对高寒地区林火管理的启示。
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.
