摘　　要： 针对云南松、地盘松、华山松易燃的活针叶在森林防火期动态变化和紫茎泽兰分布不规律的特点,测定了云南松、地盘松、华山松有叶段枝的形态学指标和相应段易燃针叶质量及紫茎泽兰茎形态学指标和质量,拟合了易燃可燃物质量与形态学指标的关系方程。经检验,实测值与预测值的结果间差异不显著,利用枝和茎的形态学指标估测易燃可燃物质量是可行的。 According to the mass dynamic changing characteristic of live leaf of Pinus yunnanensis, Pinus yunnanensis var. pygmaea, Pinus armandii in forest fire season and irregular distribution pattern of Eupa- torium adenophorum, morphological index and fuel mass of branch section with flammable live leaves of the 3 species conifer plants and stem of Eupatorium adenophorum were measured, then the equations of correlation between fuel mass and morphology index were fitted. The testing result showed that there was no obvious difference between factual value and calculated value of the equations, and it was feasible to estimate flammable fuel mass according to morphological index of branch and stem.
