As the research object, is now the most economically developed areas in Yunnan province,so today I collect 2005--2014 years of relevant data for data comparison.The city in the middle of Yunnan region the past 10 years there were 1248 times forest fires, with a total affected area of 6362.095 hectares of forest, mostly occurs in spring and winter.Affected by drought in 2010, the total number of forest fire reaches 209.Through analysis of the elements due to meteorological factors controllability is very low, so this paper mainly consider socio-economic factors. When the economy is more developed, the forest coverage rate of forest fires in the area of vulnerability greater impact when the economy is lagging behind, economic factors will be the most important factor. Keywords: forest fires, fragility analysis, factor analysis 目录 摘要 I Abstract II 1 绪论 1 1.1 研究背景 1 1.2 研究目的和意义 2 1.3 国内外研究概况 3 1.4 研究内容和技术路线 4 1.4.1 研究内容 4 1.4.2 技术路线 5 2 滇中地区森林火灾特点及成灾机制分析 6 2.1 研究区概况 6 2.2 滇中城市火灾概况 6 2.3 森林火灾特点 8 2.4 森林火灾系统成灾机制分析 9 2.4.1 致灾因子子系统 10 2.4.2 孕灾环境子系统 10 2.4.3 承灾体子系统 12 3 滇中城市群森林火灾脆弱性影响因素 13 3.1 滇中城市群火灾现状以及森林火灾脆弱性的影响因素 13 3.1.1 滇中城市群森林火灾现状 13 3.1.2 自然因素对森林火灾脆弱性的影响 14 3.1.3 社会因素对森林火灾脆弱性的影响 17 4 结论与展望 23 4.1 数据来源 23 4.2 基本结论 23 4.3 基本措施 24 4.4 论文的不足之处 25 参考文献 26 致谢 ....................................................................................................................28 导师简介 29 附录 ...........................
