| 摘 要： | 2018年9月,台风"山竹"对粤港澳大湾区城市的园林树木造成重大伤害,调研粤港澳大湾区6个城市的园林树木的受损情况,统计各树种的综合受损率及受损表现,应用聚类分析法,对受损树种进行分级,并确定树种整体受损等级。通过记录树木受损情况及分析树种自身的抗风特性,分析总结影响园林树木抗风性能的主要因素,包括树种本身的抗风特性、台风风力与风向、立地土壤环境、种植穴空间、植物群落密度、迎风口种植位置等,并提出建立完善的树木风险评估体系,加强园林绿化建设及养护管理,以增强城市园林树木抗风能力。

Investigation on the Infl uence of Typhoon Mangkhut on Urban Trees in Guangdong-Hong Kong-Macao Greater Bay Area |

| Abstract: | In September 2018,Typhoon Mangkhut caused severe damage to landscape trees in Guangdong-Hong KongMarco Greater Bay Area.This paper investigated the damage of landscape trees in six cities of Guangdong-Hong KongMarco Greater Bay Area,and analyzed the comprehensive damage rate and damage performance of these tree species.Cluster analysis was used to cluster and classify damaged tree species,and to determine the overall damage level of the tree species. By recording the damage of trees and analyzing the wind resistance characteristics of the tree species,the paper summarized the main factors affecting the wind resistance of landscape trees in Guangdong-Hong Kong-Marco Greater Bay Area,including tree species,typhoon wind-force and wind direction,local soil condition,planting space,plant community planting,density,upwind planting position,etc. In order to enhance the wind resistance of landscape trees,it was suggested to establish a tree risk assessment system,and strengthen the construction and maintenance of garden greening. |
