吉林省常见灌木树种抗火性研究

The fire resistance research of common shrub species in Jilin province

通过对吉林省18种常见灌木树种的理化指标测定、生物生态学调查和实验室林火行为试验,选取21个指标,应用专家打分法、灰色关联分析法和聚类分析法评价灌木树种抗火性,结果表明:Ⅰ类——抗火性强树种为小叶丁香、金叶榆,Ⅱ类——抗火性较强树种为榆叶梅、红瑞木、小叶女贞、早锦带花和紫丁香,Ⅲ类——抗火性一般树种为珍珠梅、茶条槭、金银忍冬、金山绣线菊、鸡树条荚蒾、山里红、紫穗槐、刺玫蔷薇、连翘和珍珠绣线菊,Ⅳ类——抗火性弱树种为铺地柏。

The shrub species fire resistance was evaluated by choosing 21 indexes and applying expert scoring method,grey correlation analysis method and clustering methodology through physical and chemical indicators measure,bioecology investigation and forest fire behavior experiment in laboratory of 18 common shrub species in Jilin province. The result showed that the strongest anti-fire shrub species included Syringa microphylla Diels and Ulmus pumila cv. Jinye. The strong anti-fire shrub species included Prunus triloba Lindle.,Cornus alba L,Ligustrum quihoui,Weigela praecox and Syringa oblata Lindl. The general anti-fire shrub species included Sorbaria sorbifolia,Acerginnala,Lonicera maackii( Rupr.)Maxim.,Spiraea × bumalda ‘Gold Mound',Viburnum sargentii,Crataegus pinnatifida Bge. Var. Major N. E. Br.,Amorpha fruticosa,Rosa davurica Pall,Forsythia suspensa( Thunb.) Vahl and Spiraea thunbergii. The weak anti-fire shrub was Sabina procumbens( Endl.) Iwata et Kusaka.
