本世纪80年代以来,人们普遍重视林火行为的研究,因为它标志着森林防火科学进入到一个新阶段。现代化林火管理离不开林火行为的研究,计划烧除和林火预报更需要林火行为指标为其提供依据。近年来我国森林防火专家发表了许多林火行为的学术论文,开创了我国林火行为研究的新篇。我们在80年代中后期至90年代初,连续开展这方面的野外测试。不但测试林火行为指标,同时还平行观测了样地的梯度气象状况。这里着重研究两种易燃 Since the 1980s, people generally pay attention to the study of forest fire behavior, because it marks the forest fire prevention science has entered a new stage. Modern forest fire management can not be separated from the research of forest fire behavior. It is more necessary to calculate the forest fire behavior index for plan burning and forest fire forecasting. In recent years, China’s forest fire experts published a number of academic papers on forest fire behavior, creating a new chapter in China’s forest fire behavior research. We conducted field tests in this area continuously in the late 1980s and early 1990s. Not only test forest fire behavior indicators, but also a parallel observation of the sample gradient weather conditions. Here focused on two kinds of flammable
