摘　　要：在泸州、宜宾、富顺、洪雅、眉山、丹棱、沙湾、夹江、沐川等地的各种立地条件和不同年龄的林分中,调查了巨桉人工林标准地175块。通过比较选出了H=0 20871+2 92447A-0 11921A2作为巨桉人工林地位级导向曲线的最优模型,用等分法编制了地位级表,并对其精度进行了检验,符合要求。175 sampleplots were surveyed in Eucalyptus grandis plantations with different ages and in different site condition. The plantations distribute in Luzhou, Yibing, Fushun, Hongya, Meishan, Danling, Shawan, Jiajiang, Muchuan cities or counties etc. in Sichuan Province. After comparison and analysis of the model, H=020871+292447A-011921A2, was selected as the option function for the guide cure of site class table of Eucalyptus grandis. At last, the site class table of the species was established with the help of bisect method. The accuracy fits for the function was tested and the result was satisfactory.
