森林地被可燃物是引起森林火灾的重要原因 ,掌握森林地被可燃物的载量分布 ,对森林火灾的预防有着十分重要的意义。通过对辽东地区不同森林类型的调查 ,搞清楚了一些常见的主要林型地被可燃物平均载量情况 ,同时对油松人工纯林、落叶松人工纯林和天然阔叶杂木林 3个具有代表性的林型 ,按不同林分密度、林龄、坡向和坡位等因素 ,进行地被可燃物载量分布状况调查 ,结果表明 ,辽东中、北部地区载量大于辽东南部地区 ;林分密度和林龄愈大 ,则载量愈高 ;南坡载量大于北坡 ,北坡最小 ;坡位愈高 ,则载量愈小
Forest land is a combustible material is an important cause of forest fires, master the distribution of forest land by combustibles, forest fire prevention is of great significance. Based on the investigation of different forest types in Liaodong area, the average load of some common forest types on combustible material was ascertained. Meanwhile, three of the three natural forests of Pinus tabulaeformis, Larch artificial natural forest and natural broad-leaved mixed forest Representative forest types, according to different stand density, stand age, slope direction and slope position and other factors, were investigated on the distribution of combustible load. The results show that the load in the central and northern part of Liaodong is greater than that in the southeastern part of Liaoning. The higher the densities and ages are, the higher the loading is. The loading on the south slope is greater than that on the north slope and the north slope is the smallest. The higher the slope is, the smaller the loading is
