| 中文摘要: |
| 选择南昌西郊和北郊12个园林树种不同器官理化性状测定分析和燃烧试验,根据各树种的含水率、燃点、热值、粗灰分、粗脂肪、木质素、粗纤维、燃烧时间、火烧强度和生物生态学特性等10个因子,应用DPS聚类分析法,对12个园林树种的燃烧性进行了排序,结果表明,难燃树种有5个,依次是:乐昌含笑、珊瑚树、大叶黄杨、白玉兰和海桐;较难燃树种有4个,依次是:女贞、山茶、夹竹桃和含笑;易燃树种有3个,依次是:桂花、巴东木连和红花檵木。为南方防火林带的建设提供了目前公认以外的防火树种。 |
| 英文摘要: |
| Twelve landscape species from western and northern suburbs of Nanchang were used to determine different organs physical and chemical properties,for combustibility and fire-resistance tests.Ten factors,which include moisture content,ignition point,heat value,ash content,crude fat content,lignin content,crude fiber content,burning time,fire intensity,biological and ecological characteristics,were adopted as the evaluation indices,thereby DPS cluster analysis method was used in comprehensive evaluation of combustibility.The results show that the twelve landscape species can be divided into three categories by their combustibility.The difficult-flammable species include Michelia chapensis Dandy,Viburmum odoratissimum Ker.,Euonymus japonicus Thunb.,Magnolia denudata Desr.and Pittosporum tobira(Thunb.) Ait.The secondary difficult-flammable species include Ligustrum lucidum Ait.,Camellia japonica Linn.,Nerium indicum Mill.and Michelia figo(Lour.) Spreng.The flammable species include Osmanthus fragrans(Thunb.),Manglietia patungensis Hu and Loropetalum chinense(R.Br.) Oliv.var.rubrum Yieh. |
