| 摘 要： | 基于森林火灾统计资料,采用加拿大森林火险天气指标系统(Canadian Forest Fire Weather Index System,CFFWIS)分析了浙江省森林火险期内森林火险天气指标动态变化趋势。结果表明:研究区火险期内森林火灾发生次数呈递减趋势,但每场火灾的平均过火面积呈显著增加趋势(P<0.01);细小可燃物湿度码(CFFM)和初始蔓延指标(IIS)达到显著水平(P<0.05),可作为浙江省森林火险期火险状况的良好指标;1991-2011年,研究区森林防火期内可燃物湿度指标、火行为指标及火灾控制难易度指标总体呈增加趋势。其中,春季火险期可燃物干燥状况增加趋势较秋、冬季火险期幅度大,且已达到显著水平(P<0.05)。因此,加大该区的森林火灾防控工作,尤其是春季火险期的防控工作刻不容缓。

| Abstract: | Based on forest fire statistics of Zhejiang Province, the Canadian Forest Fire Weather Index （CFFWIS） System was used to analyze the changes of forest fire weather indices during the forest fire danger period. Results showed that forest fire frequency of the study area would decrease, but the average area burned per fire would increase during the fire danger period（P＜0.01）. The Fine Fuels Moisture Code（FFMC） and the initial spread index（ISI） reached a high level and could be used as strong indicators of fire danger in Zhejiang forests（P＜0.05）. During the fire danger period of the study area, fuel moisture codes, fire behavior indices, and fire severity indices from 1991-2011 increased overall. Combustible dry conditions of the spring fire season had reached a dangerous level and had a higher rate than autumn and winter fire seasons（P＜0.05）. Therefore, forest fire prevention and control work in the region, especially in spring, is urgently needed.［Ch, 3 fig. 1 tab. 15 ref.］ |
