摘　　要：以国营雷州林业局纸浆材桉树人工林为研究对象,基于2015年1—2月调查的190块标准地数据,应用SPSS 19.0,For Stat 2.2软件,研究纸浆材桉树人工林生长与收获预估模型。结果表明:密度指数模型为SDI=1.7470No^(1.0951)e^(-3.7637t0.05-0.1742L);断面积模型为G=16.7828L^(0.1529)(1-e^(-1.0125×10-8SDI-2.1970t))^(0.5554);蓄积模型为M=e^(2.3641+0.0988L-3.0557t-1G0.9126)。研究结果可为国营雷州林业局纸浆材桉树人工林生长收获预估、森林成熟龄确定以及森林资源管理提供理论依据。The eucalyptus pulpwood plantation of State-run Leizhou Forestry Bureau was taken as the re-search object and the eucalyptus pulpwood plantation growth and yield model was studied based on the da-ta of 190 sample plots surveyed in January to February in 2015. SPSS 19. 0 and ForStat 2. 2 were used.
