摘　　要：以3年生千年桐(Aleurites montana)林分为研究对象,采用环境恒温式氧弹量热计,对千年桐不同构件的热值进行测定。结果表明,千年桐的根、干、枝、叶、种干质量热值分别为14 264.91、16 792.21、17 170.42、23 360.99、15 710.24 J.g-1,树叶热值最高,树枝次之,各器官干质量热值由高到低依次为叶>枝>干>种>根,并存在极显著差异。千年桐的生物量加权平均干质量热值为16 298.88 J.g-1。研究结果可为千年桐能源林的规划和生物能源转化工程提供基础性的参考数据,也为千年桐的能量特征和生态效率的研究提供科学依据。The thermostatic oxygen bomb calorimeter was used to determine the calorific values of roots,stems,branches,leaves and fruits of 3 years Aleurites montana plantation.The results showed that the calorific values of the dry weights of roots,stems,branches,leaves and fruits were 14 264.91,16 792.21,17 170.42,23 360.99 and 15 710.24 J · g-1 respectively.The leaves had the highest calorific values,followed by the branches.In terms of dry weight calorific values,the organs were ranked from high to low as fruits,leaves,stems,roots and branches and here were extremely significant differences among the calorific values of different organs.The average dry weight calorific value of A.montana was 16 298.88 J · g-1.The research means to provide references for the building of A.montana energy forests and the investigation of energy traits and eco-efficiency of A.montana.
