摘要: 调查、收集了四川省泸州、宜宾、洪雅、富顺、眉山等市、县的各种立地条件下的巨桉人工林标准地175块,样木330株,利用3个数学模型,采用SAS统计软件分析,通过比较选出材积生长模型v=0.0000783738d1.71182751h0.99798144,编制了巨桉短周期工业原料人工林二元材积表。经检验,平均误差为-0.052%,标准差为±3.4%,均方误为±0.85%,精度符合要求。

关键词: 巨桉, 纸浆林, 人工林, 二元材积表

Abstract: 175 sample plots were studied in Eucalyptus grandis pulpwood plantation with different ages and in different site conditions.The plantations distribute in Luzhou, Yibing, Fushun, Hongya, Meishan, Danling, Shawan, Jiajiang, Muchuan cities or counties etc.in Sichuan Province.With three deferent models, the statistics analysis(SAS program) was conducted and the best fit function v=0.0000783738d1.71182751h0.99798144 was selected for establishment of volume table with two factors d(diameter) and h(height) for pulpwood plantation of Eucalyptus grandis.The average error, standard error and root mean square error are -0.052%, ±3.4%, ±0.85%.

Key words: Eucalyptus grandis, pulpwood plantation, volume table with two factors
