摘  要:
根据吉林省1969—1980年的重特大森林火灾的统计数据,借助SPSS17.0统计软件,运用非参数检验的方法,分析了不同地区、起火月份、起火时间、林型、林龄、疏密度、气温、风速等因素对受害森林面积和过火总面积的影响。结果表明:不同地区的过火总面积之间存在极其显著性差异,延边地区的起火次数最多(127次),过火总面积的均值最大(528.878 9 hm2);不同起火月份的受害森林面积之间存在显著性差异,3月份受害森林面积的均值最大(572.021 4 hm2),而起火次数较多的月份主要集中在4、5、9、10月份,应注意春、秋两季的重特大森林火灾预防。

摘  要:
With the statistical data of the extremely large forest fires in Jilin Province from 1969 to 1980,we analyzed the impact of different regions,fire month,fire time,forest types,forest age,density,temperature,wind speed on forest area burnt and area burnt with SPSS 17.0 statistical software by using nonparametric test methods. There was significant difference between different regions of area burnt. The fire number of Yanbian region was up to 127,and the average of total area burnt was 528.878 9 hm2. There was significant difference between different fire months of forest area burnt,the mean of forest area burnt in March was 572.021 4 hm2,and the fire were mainly concentrated in April,May,September,and October.Therefore,more attention should be paid to the spring and autumn to prevent the extremely large forest fire.
