摘　　要：利用雷州林业局刚果12号桉W5无性系林分中胸径8～18 cm径阶,树高11～23 m的样木1 207株和尾叶桉U6无性系林分中胸径8～18 cm径阶,树高10～21 m的样木784株,按材种规格标准造材实测材积,且分别建立刚果12号桉W5无性系和尾叶桉U6无性系胶合板材立木出材量二元回归方程,经检验精度可靠,可供参考使用.There are 1 207 Eucalyptus ABL12 W5 trees with breast diameter of 8 - 18 cm and height of 11 - 23 m in the clones stand, there 784 Eucalyptus urophylla U6 trees with the same breast diameter range and height of 10 -21 m. They were sampled to measure the timber volume based on the timber standard. And the duality regression equation was built about the two clones stumpages. The equation passed the test with a credibility precision and could be used as experiential equation in assessing the volume.
