| 树高及树木垂直生长空间对于群落外貌（如林冠线的营造）以及复层结构的构建起到关键作用。本文以上海地区城镇绿化较为常见的23种园林树种为研究对象，对不同胸径梯度下(分别设置为10cm、16cm、22cm、28cm)的树高尺度进行调查与测定。基于所选取及调查树木样本的实测数据，对胸径—树高两者之间的关系进行回归拟合，将所涉及园林树木树高尺度划分为4种伸展类型，并讨论了树高尺度在种植设计中的应用。最后，尝试通过从冠顶角与冠重叠2个方面对林冠线进行定量化解析，以期为群落垂直结构的配置及林冠线的营造提供参考依据。 |

| Abstract: |
| The tree height and vertical space of tree growth play a key role in the construction of community appearance (such as the construction of canopy line) and double layer structure. This paper focuses on the 23 common urban landscape tree species and measures the tree height of different grade of DBH (set as 10cm, 16cm, 22cm and 28cm). Based on the collected data, we derived species-specific stem diameter-crown height relationship and assigned the 23 tree species to 4 height extension by cluster analysis. The application of tree height scale in planting design is discussed. At last, an exploratory study is conducted on the quantification of canopy lines from the aspect of the canopy angle and canopy overlapping. It is expected to provide reference for the construction of vertical structure of communities and the construction of canopy line in the process of planting design. |
