摘　　要：研究区域位于天然林保护工程重点区域大兴安岭林区,也是森林火灾频发的重灾区。收集177组可燃物资料,将其整理成列联表,做列联表分析,进行卡方检验、剩余分析、对数线性模型拟合。结果表明,此区域森林地表可燃物含水率在低海拔处含水率较高,随着海拔的升高,含水率呈现明显的降低趋势,研究结果对于大兴安岭林区森林防火具有重要的意义。The study area is located in the Daxing'anling forest area,a key area of natural forest protection engineering,which is also the most affected area of frequent forest fires.177 sets of combustible materials were collected,organized into contingency tables,analyzed contingency tables,and performed chi-square tests,residual analysis,and loglinear model fitting.The results show that the moisture content of combustible materials on the surface of forests in this area is higher at low altitude,and the moisture content shows a significant decreasing trend with the increase of altitude.The results of this paper are of great significance for forest fire prevention in Daxing'anling forest area.
