摘  要：
本文对营造能源林的1年生桉树无性系DH201-2和DH32-29两种林分进行了调查,并对6种不同密度配置下林分生长量、生物量现存量、热值以及能量生产效果等进行分析。结果表明:密度对两个无性系高生长的影响不明显,密度与胸径生长呈极显著负相关,蓄积生长受密度效应的影响极显著;单株生物量随密度的增大而减小,林分生物量则相反;热值受密度影响较小或无影响;能量生产效果随密度的增大而增大。营造能源林的主要目的是获得更多的生物质能,因此在营造能源林的时候,应结合立地条件适当密植,以提高能源林产量。

摘  要：
Stands of 1-year-old DH201-2 and DH32-29 eucalypt clones for energy-forest were investigated.The growth,retained biomass,calorific value,as well as the effect of energy production of the stands which were configured with 6 different spacings were analysed.The results showed that the effect of spacing on height growth of two clones was not obvious and spacing had an extremely negative impact on the growth of diameter at breast height(DBH),and it affected the stand volume significantly;plant biomass increased with spacing increasing,stand biomass was on the contrary;calorific value was affected by spacing slightly;the effect of energy production increased with the spacing increasing.To gain more biomass energy is the main purpose of the forest,so close planting could be made properly according to site condition when energy forests were built in order to raise energy production.
