中文摘要	通过分析滇中昆明地区19802009年30年间以10年划分的月平均气象资料,整理相关森林火灾资料,对森林可燃物进行分类,同时结合基础地形、地貌特征,研究森林火灾形成的火环境,结果表明:火环境趋于有利于森林火灾的发生。近30年昆明的月平均最高气温逐渐增加,相对湿度降低,但平均最大风速降低,而3,4月份平均月降水量几乎都是全年的最低,不足30 mm,20092013年的持续干旱对森林火灾的发生有着更深刻的影响;复杂的地形、地势也有利于森林火灾的产生、传播,特别是山高、坡陡;主要针叶树种为易燃的云南松和华山松,可燃物非常丰富,在持续干旱的背景下更易孕育重大森林火灾。
英文摘要	By using the methods listed below,the forest fire environment in Kunming area,middle-Yunnan Province was studied:1.Analyzing and contrasting the average meteorological data of each month from 19802009,which were divided into three sections every ten years;2.arranging and studying the information gathered from forest fires occurred recently in those areas;3.then classifying the local forest fuel types combined with the characteristics of basic topography and terrains.The results were as follows.Firstly,the fire environment tended to be advantageous to the forest fires with the maximum month average temperature increasing and the relative humidity decreasing while the month average rainfall of March and April stayed the lowest during the 30 years, which was below 30 mm.And the arid lasted from 2009 to 2013 significantly influenced the occurrence of the forest fires.Secondly,the complicated terrains and topography,especially the steep slopes and cliffs,benefited the forest fire,too.They helped the forest fire to ignite more rapidly,spread faster and grow bigger.The last fac-tor was the forest fuels,whose loads were very heavy. Among them,the main conifer species were Pinus yun-nanensis and Pinus armandii,which were very combustible during the constant arid periods.
