70 sample plots were set in clonal plantation of E.urophylla × E.grandis in Xijiang Forestry Bureau and stand factors of the sample plots were surveyed separately.According to diameter class,163 sample trees were selected.The sample trees were cut down and dissected in accordance with 2.0m or 2.6m.Based on actual merchantable volume,one-way equations of merchantable volume for single tree were built and a superior equation was selected.Subsequently,the sample trees were dissected to gain theoretical merchantable volume according to superior equation.Then,the one-way function merchantable volume table of E.urophylla × E.grandis for single tree was compiled.All of trees in the sample plots were dissected to gain theoretical merchantable volume according to one-way function merchantable volume table.Based on theoretical merchantable volume for stand,one-way equations of merchantable volume for stand were built and a superior equation was selected.Finally,one-way function merchantable volume table of E.urophylla × E.grandis for stand was compiled according to superior equation.The tables' precision is up to state requirements and the tables can provide reference for the production of Eucalyptus in the region.
