摘要
川渝地区位于我国西南部,地处四川盆地及巫山东部,植被以亚热带常绿阔叶林为主,引发山火原因较多。受极端高温干旱天气影响,川渝地区山火的数量和强度持续增加,给当地造成了严重的生态灾难和社会危机。在概括近期川渝地区山火案例的基础上,从氧气、可燃物和引火源3方面分析引发该地山火的主要原因,并从地形、气候和植被方面分析扑救难点,从多角度出发提出相应山火防控策略。
Sichuan and Chongqing region is located in the south-west of China:the Sichuan Basin and the east of Wushan. The vegetation is mainly subtropical evergreen broad-leaved forest,and the fire source is mainly caused by human activities. Affected by extreme heat and drought, the number and intensity of fires in Sichuan and Chongqing have continued to increase,causing serious ecological disasters and social crises. On the basis of summarizing the recent cases of mountain fires in Sichuan and Chongqing, this paper analyzes the main causes of the mountain fires from three aspects: oxygen, combustible materials and ignition sources, and analyzes the difficulties in fighting the fires from the terrain, climate and vegetation. Finally, it puts forward the corresponding prevention and control strategies from multiple perspectives.
