摘要
为了研究森林可燃物对林火的发生及发生后林火行为的影响程度,采用小样地调查方法对四川省西康磨盘林区的云南松(Pinus yunnanensisFranch)林内的可燃物及火行为进行调查,对标准地中的火蔓延速度、火强度、火焰高度进行相关性分析;对不同火强度下烧失率进行统计。试验结果表明:定期进行计划火烧,能减少可燃物积累,降低森林可燃性,具有良好的防火功能;在进行有计划的烧除林内枯枝落叶时,必须有效地控制火强度。
In order to study the degree of effect of the forest fuel on the fire occurrence and forest fire acts after occurrence, the fuel and fire behavior in the forest area of Pinus yunnanensis in Sichuan Xikangmopan forest area were investigated with small sample plot investigation method, the correlation analysis of fire spread speed, fire intensity, blaze height on the sample plot were conducted; the ignition loss ratio was counted up under different fire intensities. Test results showed that the planned bum was conducted in certain time, which could reduce the fuel accumulation, decreased the forest combustibility, and possessed fine fireproofing function; the fire intensity should be controlled effectively during stick and defoliation inside forest were burnt on plan.
