福建省主要防火树种发热量的研究

通过对主要防火树种与杉木、马尾松发热量的比较研究表明，防火树种的总发热量与挥发份发热量均比针叶树低，其中以木荷为最低。多元回归分析表明，在绝干条件下，影响树叶发热量的主要因于是苯—乙醇抽取物、木质素与粗灰分等。

Studies on the Caloric Amount of Main Fire Prevention Tree Species in Fujian Province

In this paper, the caloric amount of main fire prevention tree species and Chinese fir ＆ Masson’spine is studied comparatively. The results show that the total caloric amount and volatile caloric amount ofmain fire prevention tree species are lower than those of coniferous tree species，among which those of Schi-ma superba are the lowest．The multivariate regression analysis indicates that the main factors affecting leafcaloric amount are benzene-alcohol abstract, lignin，coarse ash content．etc. under the absolutely dry condi-tion.
