摘要
实践证明,树干的抗燃性大于枝条,枝条的抗燃性大于枝叶,枝叶的抗燃性是抗林火树种优劣的重要标志,也是该树种所含物质的综合反映;同一树种含水量高低对抗燃性有着一些影响,但树种间不同含水量不能衡量其树种的抗燃性。采用静风篝火法测定树种的抗燃时间,籍此来研究抗林火树种,利用树种间最佳组合配置,使生态防火阻隔效能达到更高的水平。
Practical experience proved that fire resistance of trunk is better than that of branch which is better than that of twig. Therefore, fire resistance of twig is an important symbol of the tree species as well as indicated comprehensive content of the species. The variation of moisture content of the same tree has effect on fire resistance, but different moisture content of different tree species may not be judgment of its fire resistance. Fire resistant duration was measured by bonfire in order to study fire resistance to different trees and to maximize ecological fire resistance with the best integration of tress species.
