【摘要】 对辽宁西北部地区主要林型地被可燃物种类、组成、载量以及燃烧性进行了研究,结果表明:该区有7种主要常见林型,各种林型下可燃物种类组成和盖度有明显不同,林下可燃物载量变化范围是2.76~29.71 t.hm-2。按地被凋落物的燃烧性测定指标综合分析确定,容易燃烧的林型是油松人工纯林,较易燃烧的林型是樟子松人工纯林、天然栎树疏林、天然杂木林和沙棘人工纯林,不易燃烧的林型是刺槐人工纯林和杨树人工纯林。更多还原

【Abstract】 The fuel kinds components,fuel loading,and fuel combustibility were studied in area of Northeast Liaoning Province.The results showed that there were 7 main frequent forest types.The composition of fuel and cover degree were obviously different to each stand;Under all stands,the change ranges of fuel loading were from 2.76t·hm^-2 to 29.71t·hm^-2.According to synthetical analysis of combustibility of fuel by experiment mensuration in laboratory,the sequence of combustibility were made certain.The easy combustible material was Pinus tabulaeformis,the next were Pinus sylvestris var.mongolica,Ouercus mongolica,natural weed trees.and Hippophae rhamnoides.The difficult combustible materials were Robinia pseudoacacia and Populus spp.更多还原
