背景和目的：大多数对全球能源使用的预测预测，生物质将在未来几十年内成为一次能源的重要组成部分。短轮伐期人工林具有较高的生物量产量、良好的固体燃料燃烧质量、生态优势和较低的生物质生产成本，有可能成为欧洲可再生能源的重要来源。材料和方法：在本研究中，刺槐、白柳、三角杨和欧美杨的木材。I-214，年龄8岁。结果：柳树、杨树和刺槐木材密度的平均值分别为341 kg/m(3)、336 kg/m(3)和602 kg/m(3)。柳树和刺槐木材的平均热值分别为18.599 MJ/kg、18.564 MJ/kg和21.196 MJ/kg。刺槐木材的FVI指数(平均值)(17.186)高于杨树和柳树无性系，分别为11.312和11.422。结论：刺槐木材的密度、热值和灰分含量高于杨树和柳树木材，是一种更适合作为资源利用的原料。然而，从应用这些树种的木材作为资源的角度来看，也要考虑作为“能源林”建立的人工林单位面积生物量的影响。
Background and Purpose: Most projections of the global energy use predict that biomass will be an important component of primary energy sources in the coming decades. Short rotation plantations have the potential to become an important source of renewable energy in Europe because of the high biomass yields, a good combustion quality as solid fuel, ecological advantages and comparatively low biomass production costs.Materials and Methods: In this study, the wood of black locust Robinia pseudoacacia, white willow Salix alba L., poplars Populus deltoides and Populus x euramericana cl. I-214, aged eight years were examined. Immediately after the felling, sample discs were taken to assess moisture content, ash content, the width of growth rings, wood densities and calorific values, according to the standard methodology.Results: The mean values of willow, poplar and black locust wood density were 341 kg/m(3), 336 kg/m(3) and 602 kg/m(3), respectively. The average heating values of willow poplar and black locust wood were 18.599 MJ/kg, 18.564 MJ/kg and 21.196 MJ/kg, respectively. The FVI index (average values) was higher for black locust (17.186) than for poplar and willow clones, which were similar: 11.312 and 11.422 respectively.Conclusions: Black locust wood with a higher density, calorific value and ash content compared to poplar and willow wood proved to be a more suitable raw material as RES. However, it is very important, from the aspect of the application of wood of these tree species as RES, to also consider the influence of the biomass yield per unit area of the plantations established as "energy plantations".
