为使在森林资源调查、生产、科研中更有效、迅速、快捷、准确衡量林分的优劣、好坏、疏密度的大小、蓄积量的高低,并为确定疏伐强度的强弱、估算预期目标蓄积量及木材产量提供科学的理论依据,现特编雷州刚果12号桉(W5无性系)林分标准表、林分蓄积量表与林分高径比立木材积表以供应用。 In order to make the forest resource investigation, production and scientific research more effective, rapid, rapid and accurate measurement of forest quality, size, density and stock volume, and to determine the strength of the thinning, estimation Expected target volume and timber production to provide a scientific theoretical basis, is now specially compiled Leizhou Congo 12 Eucalyptus (W5 clonal) stand standard table, stand volume and stand height and diameter ratio stand timber volume for use.
