摘　　要：在韶关市曲江区、曲仁区和浈武区的20个乡镇各种立地条件和不同年龄的桉树(尾巨桉、巨尾桉)林分中,调查了标准地93块。利用调查资料拟合的树高与年龄导向曲线回归方程为H=101.4359-1.7882//A。作为桉树短周期工业原料林地位指数表导向曲线的最优模型,用标准差调整法编制了桉树短周期工业原料林地位指数表,并对其精度进行了检验。Ninety-three Eucalyptus sample plots which distributed in 20 villages and towns from Qujiang, Quren and Zhenwu districts of Shaoguan were surveyed under different ages and different site conditions. By investigating the data and calculations, obtained the curve regression equation of tree height-age relations, H = 1 0^1.4359- 1. 7882/A. which was selected as the optional model of guide curve of site index for short-rotation industrial timber eucalyptus plantation. The site index table of Eucalyptus plantation was complied with adjusting standard deviation. The model was tested and it s accuracy could met the requirement.
