摘　　要：以阜新地区4种林型凋落物为研究对象,在防火期开展可燃物载量动态监测及其燃烧性研究。结果表明:油松落叶松林可燃物载量最大,4种林型可燃物载量最大值均出现在4月和10月中下旬至11月中上旬;油松栎林可燃物平均含水率最小,4种林型含水率低于10%出现在春季3月中下旬至5月。4月16日至5月15日可燃物载量最大,含水率最小,是该地区林火发生高危期。燃烧性能排序为油松纯林>油松栎林>油松荆条林>油松落叶松林,油松纯林的易燃性高于油松与其它树种混交林,是该地区林火发生高危林型。In the fire prevention period,dynamics of fuel load of four forest types and their combustibility were monitored in Fuxin.The results showed that the fuel loads of Pinus tabulaeformis and Larch mixed forest was the largest.The maximum fuel load of four forest types appeared in April,and from mid-late October to mid-early November.The average water content of fuel in P.tabulaeformis and oak mixed forest was the smallest,and the water content of fuel in four forest types was lower than 10%from mid-late March to May in spring.From April 16th to May 15th,the maximum fuel load and the minimum water content were both reached,and it was the high-risk periods for forest fires in this region.The combustion of fuels from high to low was pure P.tabulaeformis forest>P.tabulaeformis and oak mixed forest>P.tabulaeformis and Vitex mixed forest>P.tabulaeformis and Larch mixed forest.The combustion of pure P.tabulaeformis forest was higher than that of P.tabulaeformis mixed with other tree species,and it was the high-risk forest fires type in this region.
