摘　　要：为了探讨美洲黑杨(Populus deltoides)作为生物质能源林的可行性,并进一步筛选更有潜力的适合作为生物质能源林的无性系,以8个美洲黑杨无性系为参试对象,按照随机区组试验营造生物质能源林,并测定了胸径、株高等17个指标,采用多元统计分析中的主成分分析方法和多元线性回归分析方法,对数据进行了分析。结果表明:8个无性系均为生物质能源林的重要树种,其中,2号无性系最优,其次为4号和3号无性系。采用逐步回归的分析方法,拟定了单株生物量(W)与胸径(D)、株高(H)的回归方程,为W=2.878 7D+0.655 3H-16.528 0,通过测定胸径和株高,可以快速估算其生物量,从而为美洲黑杨生物质能源林经营提供重要参考。In order to explore the feasibility of Populus deltoides as a biomass energy forest and to further select more promising clonal varieties suitable for biomass energy forest, a study was conducted with eight clonal P. deltoides as subjects. A randomized block design was implemented to establish biomass energy forests, and 17 indicators, including diameter at breast height and plant height, were measured. Data analysis was performed using principal component analysis and multiple linear regression analysis. The results showed that all eight clones are important species for biomass energy forests, with clone 2 being the most optimal, followed by clones 4 and 3. Using a stepwise regression approach, a regression equation was developed for individual biomass ( W ) in relation to diameter at breast height ( D ) and plant height ( H ), resulting in W= 2.878 7D+ 0.655 3H-16.528 0 . By measuring the diameter at breast height and plant height, biomass can be quickly estimated, providing important references for the management of P. deltoides biomass energy forests.
