园林树种抗火性研究现状

Research Status of Fire Resistance of Landscape Tree Species

随着气候变化的加剧,各种自然灾害变得越来越严重,发生频率也日趋增多。其中全球火灾发生率不断攀升,给人居环境带来了日益严峻的挑战,城市火灾直接关系到居民生命财产的安全及绿化生态体系的健康。园林树木具有阻隔火灾蔓延的能力,科学的规划和配置能有效提升城市的防灾避险水平,促进人居生态的可持续发展。本文在对国内外绿化树木抗火性研究、评价和树种筛选文献综述的基础上,探讨了目前研究存在的不足,提出了未来研究的展望,为提升绿化系统的生态韧性提供了理论对策。

With the intensification of climate change,various natural disasters are becoming more and more serious and their frequency is increasing.The increasing incidence of global fire has brought increasingly severe challenges to the living environment.Urban fire is directly related to the safety of residents'lives and property and the health of the green ecosystem.Landscape trees have the ability to block the spread of fire,and scientific planning and allocation can effectively improve the level of urban disaster prevention and hedge,and promote the sustainable development of human settlements.Based on the literature review of the research and evaluation of the fire resistance of green trees and tree species selection at home and abroad,the shortcomings of the current research were analyzed and the prospect of future research was puts forward,and theoretical countermeasures for improving the ecological resilience of green systems was proposed in this paper.
