摘要
利用雷州林业局尾叶桉U6无性系林分中胸径4～18 cm,树高5～21 m的样木1 059株,按2 m区分段实测材积,建立基径二元材积回归方程和一元基径与树高回归方程,用尾叶桉U6无性系立木基径二元材积式编制了一元材积表,经检验精度可靠,可供参考使用.
est bureau. There The information for establishing this volume table are collected from analytic trees in Leizhou for- are 1 059 trees of Eucalyptus urophylla U6 Clone Plantations was collected which are 4 - 18 cm diameter,5 - 21 m height. Estimation of parameter for equation of volume testified the tree volume table is reliable
