摘　　要：编制广东省韶关市桉树短周期工业用材林二元材积表,为桉树森林经营中蓄积量计量以及生产应用提供科学依据;调查收集了金韶关速生丰产林公司20个乡镇不同立地条件、不同林分年龄和不同造林密度下的桉树工业用材林样木527株,利用8个数据模型,采用DPS统计软件分析;通过比较选出最佳材积生长模型,编制了桉树(尾巨桉、巨尾桉)短周期工业用材林二元材积表;模型8经精度检验,平均误差为0.39%,系统误差为±1.1%,精度符合林业生产和应用要求。The paper focused on establishment of volume table with two factors for short-rotation industrial Eucalyptus plantation in Shaoguan, which offers scientific bases for volume calculation and application of Eucalyptus forestry management. 527 sample Eucalyptus industrial timber trees were measured in 20 villages and towns with different site conditions, ages and density, 8 data models were conducted, the best volume increment model： 1,1 = D2（0.00022 ＋ 0.000023H）and volume table with two factors D （diameter） and H （height） for short- rotation industrial Eucalyptus plantation were established. The average error and system error were 0.39%, ±1.1%, respectively in model 8, its precision was eligible to be used in forestry production and application.
