充分利用木质能源对于缓解我国能源危机,减轻生态负荷有很大作用。为此,对广西省北海市合浦县内桉树、厚荚相思和马占相思三种速生树种的热值进行试验研究。结果表明,桉树的热值为19.782kJ/g,马占相思的热值为20.640kJ/g,厚荚相思的的热值为20.978kJ/g;桉树、厚荚相思和马占相思三树种的各器官中,热值由高到低的顺序大致为树叶和树枝、树干边材、树干心材和树皮,其中,马占相思树皮的发热量界于树叶与树枝之间。

Making full use of wood energy is quite significant to ease China＇s energy crisis and to reduce the ecological load.An experiment was conducted to study the calorific value of Eucalyptus,Acacia mangium and Acacia crassicarpa in Hepu couty of Beihai city,Guangxi province.Results show that the calorific value of the three species is 19.782kJ/g,20.640kJ/g and 20.978kJ/g,respectively.The calorific value of the organs in each species from high to low order is almost the same,which is leaves,branches,sapwood of the trunk,heartwood of the trunk and bark.However,the value of bark in Acacia crassicarp is between its leave and branch.
