摘　　要：川西地区是森林火灾发生的高风险地区之一。研究川西地区常见灌木物种的燃烧性状,有利于评估不同灌木发生火灾的风险及强度,帮助筛选抗火物种用于生物防火。本研究选取川西地区常见的12个灌木物种,分别测定了灌木枝条的含水率、灰分、燃点、热值;利用主成分分析,评价了不同物种的燃烧性差异。结果表明,不同物种间,灰分、燃点、热值的差异显著,含水率的差异也较大。通过综合分析性状之间的差异,将灌木抗火性分为三类:较强抗火性、可抗火性、弱抗火性。其中西南木蓝、小叶栒子为较强抗火性灌木;鲜黄小檗、槲树(幼苗)、铁仔、忍冬、小叶蔷薇、散生栒子、滇榛为可抗火性灌木;大白杜鹃、微柔毛花椒、金露梅为弱抗火性灌木。本研究对川西地区常见灌木物种的燃烧性进行测定分析,为当地的火灾预防提供了基础数据。Western Sichuan region is one of the high-risk areas for forest fires.Study on the flammability-related characteristics of common shrub species in western Sichuan region is helpful to assess the risk and intensity of wildfires for different shrubs,and facilitate to identify the fire-resistant species for biological fire protection.In this study,twelve common shrub species in western Sichuan region were selected to determine the moisture content,ash content,ignition point and calorific value of shrub branches respectively.In addition,principal component analysis was used to evaluate the variation of flammability-related characteristics of different species.The results showed that there were significant differences in ash content,ignition point and calorific value among different species,and there were also great differences in water content.According to the comprehensive analysis of the flammability-related characteristics,the 12 shrubs could be divided into three categories:strong fire resistance,fire resistance and weak fire resistance.Among them,the southwest wood blue and cotoneaster were shrub species with strong fire resistance;three needles,oak tree(saplings),iron jaundice,honeysuckle,rosemary,scattered cotoneaster Zi and Dian Hazel were fire-resistant shrub species;Rhododendron,Zanthoxylum bungeanum and Potentilla fruticosa were weak fire-resistant shrub species.In this study,the flammability-related characteristics of 12 shrub species from western Sichuan region were measured and analyzed,which provided data for local fire prevention.The flammability-related characteristics of 12 shrub species from western Sichuan region were measured and analyzed,which provided data for local fire prevention.
