摘要 对建阳区历年来3次最大典型森林火灾与气象因子的相关性研究表明:气温较高、相对湿度较小、风速偏大时,火灾发生概率较大,且空气温度为最主要气象因子。根据3次森林火灾气象要素的日变化规律看,下午14时左右是森林火灾发生的重要时段。且火灾与其发生的前3 d气象要素相关,即前3 d气温越高、空气相对湿度越小、风速越大,火灾越容易发生,各F值均大于F0.01(F0.01=7.5910),达到极显著。风速不仅影响森林火灾的发生,还直接影响其蔓延。 The correlation between forest fire and meteorological factors about three times of the biggest typical forest fire in Jianyang District had been studied. The results showed that the fire probability was larger when meeting relatively high temperature, low humidity and faster wind speed. Meanwhile the air temperature was the most important meteorological factor. Based on the diurnal variation of meteorological factors about these three forest fires, the period around 14 pm was an important time for forest fire. And the fire was related with the meteorological factors of the previous three days, with high temperature, low humidity and faster wind speed. Each F value was greater than F0.01 (F0.01 = 7.5910) and reached a significant level. The wind speed not only had affected the occurrence of forest fire, but also had decided its spread.
