安徽省防火树种的选择及评价研究

在大量的野外调查测定和室内分析基础上,应用回归和主成分分析、模糊聚类、多目标决策等方法,对安徽省15种针阔叶树种的抗火性能进行了排序、分类和评价.结果表明,拟选的 15种树种依据其抗火性及经济性状可分为4类,即:Ⅰ类树种(抗火性很强)--木荷,是皖南、大别山南坡及皖东部分地区的首选防火树种;Ⅱ类树种(抗火性强)--油茶和珊瑚树;Ⅲ类树种(抗火性较强)--甜槠、苦槠、石栎、青冈栎、茶树、厚皮香、交让木和女贞;Ⅳ类树种(抗火性弱)--马尾松、湿地松、杉木和香樟,这类树种不宜作防火树种,而是被保护的对象.

Selection and Evaluation of Fire-resistant Tree Species in Anhui Province

Based on investigation and indoor analyse, by means of regression and main component analyse,fuzzy classification and multi-target determination, the fire-resistance of the fifteen needle-broadleaved forest species were sequenced, classified and evaluated. The results showed that the selected fifteen species can be classified into four groups according to their fire-resistance and economic characters, namely,species type(powerful fire-resistance)-Schima superba,which is the first selected fire-resistant forest species in the southern and eastern part of the Anhui Province as well as the southern slope of the Dabie Mountain.species type(strong fire-resistance)-Camellia deifera,Viburnum awabuki.species type(good fire-resistance)-Castanopsis eyrei,Castanopsis sclerophylla,Lithocarpus glabra,Cyclobalanopsis glauca,Camellia sinensis,Ternstroemia gymnanthera,Daphniphyllum macropodum and Ligustrum lucidum etc.species type(mild fire-resistance)-Pinus massoniana,Pinus elliottii,Cunninghamia lanceolata and Cinnamomum camphora,which are unsuitable for the fire-resistant forest species but the one that should be protected.
