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/hm2,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。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 .
