| 行道树的树种组成、稳定性和生长特征显著影响着
其生态功能，在一定程度上也反映了人居环境质量。以太原市
绕城高速范围内的区域为研究对象，通过布设样点选取了269
条样带，调查了树种应用情况、生长参数及其环境特征，并探
索了行道树参数与社会经济因素(建筑核密度、房价、人口密度
和GDP)的关系。本次调研统计测定了2 185棵行道树，发现
太原市行道树共有19种，隶属于11科12属，树种应用较为单
一，其中国槐(Sophora japonica)应用占比高达67.41%。
太原市行道树树高结构和年龄结构分布极不均匀，以中幼年树
为主。行道树各生长参数沿支路、次干道和主干道依次递减。
此外，研究发现行道树生长参数与社会经济因素相关性显著，
在一定程度上反映了城市化进程中街道绿化效果与经济水平的
一致性，从社会层面揭示了行道树生长的驱动机制 |

| Abstract: |
| Tree species composition, stability and growth
characteristics influence the ecosystem services of street trees,
which contribute to residents' health and environmental quality.
This research recorded the attributes of each tree in 269 selected
sampled transects in Taiyuan, China, analyzed the street tree
composition and growth structure characteristics and explored the
association with socioeconomic variables (building density, housing
price, population density and GDP) at a fine scale. A total of 2,185
trees were counted and belonged to 19 species, 11 families and 12
genera. Sophora japonica was the most dominant species (67.41%).
The height and age structure of street trees was unevenly distributed
and mainly composed by maturing and young trees. There were
decreasing mean growth characteristics (height, crown diameter,
diameter at the breast height, basal diameter, branch height) along
the street grades from branch roads and sub-arterial roads to
arterial roads. Additionally, the results also indicated tree attributes
significant correlated with socioeconomic factors, reflected the
consistency between street greening effect and economic level,
and revealed the driving mechanism of street tree growth in social
aspect. |
