| 摘 要： | 在对广西沙塘林场巨尾桉2年生人工林调查基础上，按标准木法测定巨尾桉人工幼林生物量，建立其估算模型，计算出巨尾桉人工林分的生物量和生产力，分析各器官生物量分配规律及林分生产力水平。结果表明，2年生巨尾桉人工林年生物量为16.57 t/hm^2，其中，干、根、叶、枝、皮各器官生物量所占比例依次为46.67％、16.85％、14.62％、12.16％、9.62％。应用建立的估算模型估测巨尾桉人工幼林生物量，其相关程度达显著水平。

| Abstract: | Based on the survey of 2-year-old Eucalyptus grandis ＆#215;Eucalyptus urophylla plantation at Shatang forest farm in Guangxi Province , the standard wooden method and an estimation model were used to calculate the biomass of E.grandis ＆#215;E.urophylla plantation , and the biomass and its distribution in different organs were also analyzed . The results showed that the annual biomass of 2-year-old E.grandis ×E.urophylla plantation was 16.57 t/hm^2 , the proportion of biomass distribution in different organs , namely stem , root , leaf , branch and bark were 46.67 %, 16.85%, 14.62%, 12.16%and 9.62%respectively , the biomass correlation of young E.grandis ×E.urophylla plantation and the estimation model was significant . |
