摘要: 本文利用1991-2005年台州市发生的全部森林火灾资料和各县(市、区)当时的逐日气象资料,用MATLAB语言进行平行相关分析、作图,找出影响森林火灾发生的关键气象因子,并得出台州市森林火灾发生的规律,具有显著的亚热带东南沿海地区的气候特点和规律:①随最低气温降低,森林火灾次数概率出现极明显的增加;②最小相对湿度能较好地反映天气的干燥情况,可以作为森林火险等级预报的主要依据之一;③风速、降水、日照等与森林火灾次数、过火面积都没有显著的相关性,在风力较小、有降水、无日照的天气条件下,出现了相当数量的火灾个例,本研究旨在为台州市森林火灾的预防提供理论依据。

Abstract: Based on data of occurrences of the forest fire and daily meteorological data in 1991-2005 in Taizhou City of Zhejiang Province,the key meteorological factors affecting the occurrence of the forest fire were analyzed and constructed by the parallel correlation analysis with the Matlab.The results showed that the probability of the appearance number of the forest fire increased as the minimum air temperature decreased.The minimum relative humidity well represented the dryness of the weather and could be as one of the main indexes for the forecast of the forest fire risk degree.The wind velocity,precipitation and radiation were not significant to the appearance number of the forest fire and the burned area.The quite large number of the forest fire occurred under the conditions with the low wind velocity,rain and cloudy days.
