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。
To compile the binary volume table of eucalyptus short-period commercial timber forest in Shaoguan City, Guangdong Province, and to provide a scientific basis for the stock volume measurement and production application in Eucalyptus forest management. The investigation collected the different site conditions of 20 townships in Jin Shaoguan fast-growing high yield forest company, And 527 plants of eucalyptus industrial timber with different afforestation densities were analyzed with DPS statistical software using 8 data models. By comparing and selecting the best volume growth model, the short period of eucalyptus (Eucalyptus grandis × E. grandis × E. grandis × Eucalyptus) Industrial timber forest binary volume table; model 8 by the accuracy test, the average error of 0.39%, the system error of ± 1.1%, accuracy in line with the forestry production and application requirements.
