摘　　要：森林火灾带来了严重后果,但许多人对黑色防火感到一些困惑,计划烧除是"防火"、"用火"还是"放火".随着数据分析技术的进步,运用数据库、多元统计分析等方法可以分析森林火灾调查和统计的数据,探索森林防火的最佳措施.针对黑色防火的深入理解,对试验数据进行了相关分析.该相关分析是利用了云南松林里进行计划烧除后得到的各种数据,然后通过SPSS软件来分析数据.试验结果可以表明:计划烧除时火强度、火蔓延速度与火焰高度属于正相关;火强度与森林可燃物的生物量也属于正相关,通过小强度的计划烧除能有效的减少森林可燃物的生物量,从而提高森林的自防能力.Forest fires have brought serious consequences, but many people are confused with black fire. There are several meaning of plan burning, for example fire Prevention and fire using and setting on fire. With the advances of data analysis technology, using database and multivariate statistical analysis and so on, which can be analyzed the data of forest fires survey and statistic, and explored the best forest fire prevention measures. With the in depth understanding of black fire, the experimental data were correlation analyzed. The correlation analysis is using of data of burning Pinus yunnanensis faranch, and then through the Statistical Program for Social Sciences software to analyze data. Test results showed that the fire intensity prescribed burning, fire spreading speed and flame height are positively correlated; fire intensity and the biomass of forest combustible materials also belong to a positive correlation. Through small-intensity prescribed burning can effectively reduce the biomass of forest combustible materials, thereby enhancing the self-defense capacity of the forest.
