森林燃烧所释放的热量、火种类、火行为等各种林火属性与树种易燃性密切相关,而树种的理化性质在一定程度上制约着易燃性,因此对树种理化性质和易燃性的研究是必要的。基于20种树种的实验分析,确定了可燃物热值、抽提物含量、灰分含量、含水量、密度的相关性,并建立相应的回归模型;基于树种理化性质的分析,比较了20种树种的易燃性,进行排序并划分等级。
Forest fire release of heat, fire types, fire behavior and other forest fire properties and species flammability are closely related to the physical and chemical properties of trees to a certain extent, restricts the flammability, so the physical and chemical properties of trees and flammability The research is necessary. Based on the experimental analysis of 20 tree species, the correlations between calorific value of fuel, extract content, ash content, water content and density were determined and corresponding regression models were established. Based on the analysis of physical and chemical properties of 20 tree species Flammability, sort and grade.
