广州市环市路行道树树木安全风险评估与管理探析

Safety Risk Assessment and Management of Street Trees on Huanshi Road in Guangzhou

摘要:

环市路是广州市重要主干道路，其道路绿化的安全性是城市绿化管理工作的的重要内容之一。采用视觉评估法（Visual Tree Assessment，VTA）以及无损检测法对环市路行道树树木风险进行综合评估，并分析树木形态因子与风险因子间的相关性。结果发现，环市路 11.2% 的行道树存在安全风险，不同树种的安全隐患率差异较大，且树木形态因子与风险因子间存在显著的相关性。并从树木安全风险评估与管理角度探讨行道树种植设计、施工及日常管养，推动城市绿化精细化管理。

Abstract:

Huanshi Road is an important trunk road in Guangzhou, and the safety of its road greening is one of the important contents of urban greening management. In this study, methods of Visual Tree Assessment (VTA) and non-destructive testing are used to comprehensively assess the risk of trees along Huanshi Road, and the correlation between tree morphology factors and risk factors is analyzed. The results show that 11.2% of street trees in Huanshi Road have safety risks, and the safety risk rates of different tree species are significantly different. Meanwhile, there is a significant correlation between tree morphology factors and risk factors. Finally, from the perspective of tree safety risk assessment and management, the planting design, construction and daily management and maintenance of street trees are discussed to promote the refined management of urban greening.
