| 摘 要： | 通过对30种乔灌木叶子可燃物的野外调查、取样,测得点燃含水率和蔓延含水率;应用因子分析和聚类分析方法,进行统计分析,得出这些可燃物的易燃难易和蔓延快慢程度的排序.抗火性较好的有山杨、糖槭、乌苏里鼠李、刺五加、黑桦、东北溲疏、山皂荚、东北茶藨、接骨木、东北山梅花、梓树等11种;较差的有树锦鸡儿、山丁子、刺榆、卫矛、枫杨、暖木条荚迷、秋子梨、山楂、华北卫矛、油松等10种.

| Abstract: | Based on the field investigation,sampling and the laboratory experiment,the ignition moisture content and spread moisture content of 30 tree and bush species leaves were analyzed by applying factor analysis and cluster analysis.The ordering of combustibility and spread degree of those fuels were given out.The result shows that those 11 species of Populus davidiana,Acer saccharum,Rhamnus davurica,Acanthopanax senticosus,Betula nigra,Deutzia amurensis,Gleditsia japonica,Ribes mandshuricum,Sambucus uilliamsii,Philadelphus schrenki,Catalpa ovata have relatively higher fire resistant ability.While those 10 specie of Caragana arborescens,Malus baccata,Hemiptelea davidii,Euonymus alatus,Pterocarya stenoptera,Viburum burejaeticum,Pyrus ussuriensis,Crataegus pinnatifida,Euonymus maackii,Pinus tabulaeformis have relatively lower fire resistant ability.Those results can have a help to the selection of fire_resistant species. |
