摘　　要：常绿阔叶树种是森林的主要植物种类,具有含水率高的特点。选择石栎Lithocarpus glaper、拟赤杨Alniphyllum tortunei、冬青Ilex chinensis、樟树Cinnamomum philippinense、木荷Schima superba、罗浮栲Castanopsis fabri、山杜英Elaeocarpus decipiens、甜槠Castanopsis eyrei、苦槠Castanopsis sclerophylla、油茶Camellia oleifera 10种常绿阔叶树种,采集不同树种的树叶、树枝和树皮,烘干粉碎后在室内进行理化性质的测定分析,以不同树种器官的含水率、热值、燃点、木质素、粗纤维、粗灰分、粗脂肪7个指标作为评价因素,对10个树种的抗火性进行聚类分析,结果表明:抗火性强的是冬青;抗火性较强的有3种,由强到弱依次是油茶、山杜英、拟赤杨;抗火性一般的有2种,由强到弱依次是苦槠、石栎;抗火性较弱的有4种,由强到弱依次是木荷、樟树、甜槠、罗浮栲。研究结果能为防火树种的筛选提供理论依据。Evergreen broad-leaved tree species is the main species of forests, has the characteristic of high moisture content. Ten tree species, including Lithocarpus glaper, Alniphyllum tortunei, Ilex chinensis, Cinnamomum philippinense, Schima superba, Castanopsis fabri, Elaeocarpus decipiens., Castanopsis eyrei, Castanopsis sclerophylla, Camellia oleifera, were selected as the studied tree species. Theirs l eaves, twigs and barks were gathered, dried and crushed respectively. Then, theirs physicochemical properties were measured and analyzed in indoor. By using the seven indicators of various trees organs such as moisture content, calorific value, ignition, lignin, crude fiber, crude ash, crude fat as the evaluation factors, the cluster analyses on the ten trees＇ fire resistance were conducted. The results show that the strongest tree of fire resistance was ILexchinensis Sims, the stronger trees of fire resistance were the three kinds tree, ranked from strong to weak as follows： C. oleifera, E. decipiens, A.tortunei; the general tree of fire resistance were the two kinds of tree, from strong to weak was C. sclerophylla, L. glaper; the weaker treesof fire resistance were the four kinds, from strong to weak was S. superba, C. philippinense, C. eyrei and C. fabric. The findings can provide a theoretical basis for screening the fire resistant tree species.
