摘　　要：对新疆克拉玛依地区的乔木银新杨的茎、枝、根的热值、灰分、化学组分、含碳率进行研究。结果表明:不同器官的热值为主干皮(19.701 kJ.g-1)>主干干(18.653 kJ.g-1)>侧枝皮(18.512 kJ.g-1)>侧枝干(18.135 kJ.g-1)>根干(18.075 kJ.g-1)>根皮(17.106 kJ.g-1);干的灰分含量在0.80%～1.69%之间,皮的灰分含量在8.05%～9.63%之间;相关性分析结果表明,干的热值与灰分含量之间没有显著的相关性;而皮的热值与灰分之间存在极显著的负相关性(P<0.01),相关系数为-0.58;木质素和纤维素与热值之间并没有显著的相关性(P>0.05);热值与含碳率之间存在显著的负相关关系(P<0.05),相关系数为-0.856。This paper discussed the caloric value,ash contents,chemical composition and carbon content rate of the branch,stem and root of P.alba×P.bolleana found in Kelamayi Area,Xinjiang Province.The results showed：the caloric value in various components were be ranked in the decreasing order as follows：the skin of stem（19.701 kJ·g-1）the stem of trunk（1 8.653 kJ·g-1）the skin of branch（18.512 kJ·g-1）the stem of branch（18.135 kJ·g-1）the stem of root（18.075 kJ·g-1）the skin of root（17.106 kJ·g-1）.The ash contents in different stems ranged from 0.80%～1.69%,the ash contents of the skin ranged from 8.05%～9.63%.The pertinence analysis results showed that the caloric value of stem was not correlated with its ash content,but the skin caloric value（P0.01） was negative correlated with its ash content,the correlation coefficient was-0.58;the correlation analysis showed that：the two chemical compositions were not significantly correlated with the caloric value d（P0.05）.The caloric value of P.alba×P.bolleana was negative correlated with its carbon content rate（P0.05）,the correlation coefficient was-0.856.
