一、引言燃烧值是森林可燃物燃烧性的一个重要参量,是确定林火发生与蔓延中能量释放的一个关键指标。本文系统对大兴安岭不同森林可燃物种类的燃烧值进行了测定和研究,获取了一些规律性的结果。可燃物的燃烧值是指单位可燃物完全燃烧并冷却到参加反应物质的起始温度时所释放的热量,也称热值 I. INTRODUCTION The combustion value is an important parameter for the combustibility of forest combustibles and is a key indicator to determine the energy release during the occurrence and spread of forest fires. This paper systematically measured and studied the combustion values ​​of different forest combustible species in the Greater Hinggan Mountains, and obtained some regular results. Combustible combustion value is the unit of combustible material is completely burned and cooled to participate in the initial temperature of the reaction substance released by the heat, also known as calorific value
