摘要
运用SPSS18.0统计软件,采用因子分析法对植物的含水率、粗脂肪含量、粗灰分含量、燃点、引燃时间、灰化速度6个指标进行分析,然后对云南山地应用普遍的22种城市绿地植物进行防火性能排序.结果表明,筛选出20种城市绿地防火植物,相对防火性能最好的是马蹄荷、杜英,综合因子得分分别为-17.83、-17.91;防火性能最差的是楠木,综合因子得分为-30.70.
Abstract
Using SPSS 18.0 statistical software,the moisture content,crude fat content,ash content,ignition point,ignition time and ashing speed were analyzed by factor analysis method.Then,22 kinds of urban green plants in Yunnan mountain area were analyzed and sorted.The results showed that 20 kinds of urban green fire-proof plants were selected,and the best fire-resistance plants were Exbucklandia populnea and Elaeocarpus decipiens,and the comprehensive factor scores were-17.83 and-17.91,respectively;the poor performance of fire resistance was Phoebe bonrnei,the comprehensive factor scores was-30.70.
