| 摘 要： | 对昆明地区重大森林火灾迹地进行外业调查,并对其可燃物进行系统研究。结果表明:火烧迹地的地盘松幼林、光叶石栎和紫茎泽兰的可燃物绝对含水率分别为13%、11%和12%,可燃物载量分别为0.4、0.5和1.1 kg/m2,热值分别为20700、20600和19100 kJ/kg,单位面积热量分别为8280、10300和21010 kJ/m2。说明火烧迹地的可燃物干燥易燃,在防火期有可能再次发生火灾,并发展为高强度火,应重视重大森林火烧迹地的管理、更新和恢复。

| Abstract: | The field investigation in burned area of major forest fire was carried out to systematically study the combustibles.The results showed that the absolute moisture content of combustible in Pinus yunnanensis var.pygmaea young forest,Lithocarpus maire forest and Eupatorium adenophorum forest were 13%,11%and 12%respectively,the combustible load was 0.4、0.5 and 1.1 kg/m2 respectively,the calorific value was 20700、20600 and 19100 kJ/kg respectively,and the heat per unit area was 8280、10300 and 21010 kJ/m2 respectively.The results indicated that the combustibles in the burned area were dry and flammable where the major fire may occur again,so attention should be paid to the management,renewal and restoration of major forest burned areas. |
