| 摘 要： | 通过对影响厚朴树皮产量的因子分析，提出了对单株厚朴树皮产量有直接贡献的因子是密度、树高、胸径和树干干重。在厚朴林分形成过程中，密度是影响林分厚朴树皮产量的主导因子；及时地进行合理间伐，改善林木生长环境，是提高单位面积树皮产量和整个林分质量的重要措施。

| Abstract: | The correlation of the stand structure of officinal magnolia , Magnolia officinalis,with its bark yield was studied.Factor analysis indicated that stand density,tree height,diame-ter breast high,and dry weight of the trunk are directly contributive to the yield of bark of eachindividual plant.In the process of stand establishment stand density is the leading factor that af-fects the bark yield.Accordingly, propet thinning and pruning were applied, which proved ef-fective in raising the per-unit-area yield. |

| Keywords: | Magnolia officinalis Yield of bark:Stand structure Stand density. |
