| 摘 要： | 随着生产的发展、人口的增长和人民生活的改善,农村能源消耗量将越来越大,供需矛盾将更加突出.因此开发能源树种、发展高效能源林是必然趋势.为了为能源树种及其优良个体的选择提供依据,本文以相同立地条件下3年生川滇桤木实生幼树为研究材料,对不同个体的生物量和热值进行了测定分析.结果表明:不同的幼树单株个体间的生物量差异较显著,个体器官生物量的差异显著,器官生物量的比例依次为干>枝>叶;不同器官的热值差异显著,各器官热值大小顺序为叶>枝>皮>干;生物量和热值之间几乎没有相关性;植株胸径和干生物量及总生物量间具显著相关性,建立的曲线回归方程分别为W<,1>=234.826-146.521D+70.045D<'2>,W<,2>=4274.859-1803.607D+278.687D<'2>;对该树种薪炭能源优树选掸的主要指标是总生物量,其次是热值.

| Abstract: | With the development of production,increasing population and improvement of people's live,rural energy consumption will increase and the conflict between supply and demand will become more and more seriously.It is the time to develop the high-energy forest and research the high-energy species.In this paper,three year-old seeding trees of Alnus ferdinandi-coburgii Schneid were selectee to be used as experimental materials.By measuring the trees' biomass and heat value,the results showed that individual diffe... |
