【摘要】 本文分析了37个树种的抗火性能、生物学和造林学特性,并运用模糊数学方法对上述三大因素集进行综合评判,划分等级。在此基础上进行多目标决策,建立防火林带树种选择综合评价的数学模型,共划分出五个等级。其中木荷为一级;竹柏、苦槠、青冈栎、格氏栲、闽粤栲等10个树种为二级。更多还原

【Abstract】 Three main factors-fire resistant ability, bioecological and silvicultural characteristics about 37 tree species have been analysed in the laboratory ; and have been judged and divided into grades by using Fuzzy mathematics method. Upon the above basis the synthetical evaluational model of species choice for fire protective forest belt has been further established and divided into five grades by means of polygoal decision. Grade 1 included Schima superba Garodn. et Champ. $ grade 2 enclosed ten tree species, such as Podocarpus nagi (Thunb. ) Zoll. et Mor. ex Zoll. Castanopsis scierophglla(Lidl) Schott, Cyclobalanopsis glauca(Thunb.) Oenst, Castanopsis kawakamit Hay, et al.更多还原
