| 中文摘要: |
| 城市化进程的快速推进,给城市带来热岛效应、空气污染、内涝等问题。行道树在城市生态服务方面发挥着重要作用。为提升街道的舒适性和安全性以及改善道路环境微生态,优化行道树的生态服务功能,以西安地区为研究对象,对常见的9 种健康行道树进行详细的参数测量与计算,并使用i-Tree Eco模型分别对其年固碳量、空气净化能力、年释氧量及截留雨水4 个方面的生态效益进行对比分析。结果表明,大乔木中臭椿综合生态效益最佳,悬铃木次之;中乔木中栾树、七叶树综合生态效益最佳,鹅掌楸次之。 |

| The rapid advancement of urbanization has brought problems such as heat island effect, air
pollution, and waterlogging to cities, and street trees play an important role in the function of urban ecological
services. In order to improve the comfort and safety of streets, improve the microecology of the
road environment, and optimize the ecological service function of street trees, this paper took Xi′an area
as the research object, measured and calculated the parameters of 9 common sizes of healthy street trees
in detail, and used the i-Tree Eco model to compare and analyze the ecological benefits of their annual
carbon sequestration, air purification capacity, annual oxygen release and rainwater retention. The results
showed that the comprehensive ecological benefits of Ailanthus altissima were the best among the large
trees, followed by Platanus occidentalis. Among medium-sized trees, Koelreuteria paniculata and Aesculus chinensis had the best comprehensive ecological benefits, followed by Liriodendron chinense. |
