城市树木强风环境受损研究现状及展望

Research Status and Prospect of Urban Trees Damage in Strong Wind Environment

近年城市风灾(台风等)引起的树木损坏导致的经济损伤与人员伤亡日渐严重,而针对树木风损的研究难度极大。城市树木强风环境中的损伤情况与城市区域形态、树种、种植环境、养护程度相关。通过将ArcGIS广州城市地图与2016年~2018年台风树木抢险数据叠加分析得到城市树木受损率高的城市区域和相对较易受损的树种,基于此归纳了相应城市区域的树木规划种植和养护的重点。

In recent years,the economic damage and human casualties caused by tree damage caused by urban wind disasters(typhoons,etc.)have become more and more serious,and it is extremely difficult to study wind damage to trees.The damage of urban trees in a strong wind environment is related to the urban area morphology,tree species,planting environment and conservation degree.Based on the superposition analysis of ArcGIS Guangzhou city map and typhoon tree rescue data from 2016 to 2018,the urban areas with high tree damage rate and relatively vulnerable tree species are obtained.Based on this,the key points of tree planning,planting and conservation in corresponding urban areas were summarized.
