摘要:
中国是世界上受台风影响最为严重的国家之一,研 究台风对园林树木的影响具有重要意义。目前,国内外对台风 影响园林树木的灾前预测模型研究和灾后统计分析研究的成果 较为丰富,但关于灾时台风对园林树木的影响研究较少涉及。 以深圳大学后海校区为研究范围,采用Phoenics软件进行 CFD模拟,探索灾时台风对园林树木的影响。研究发现受损 树木的分布与风速的强弱分布具有空间上的一致性。风速、树 木高度及冠幅与受损树木比例显著相关。根据分析结果,从植 物配置、立地条件改善、树木养护与管理等方面提出相应对策 建议,以期为今后园林树木抗风灾影响研究提供经验。

Abstract:
China is one of the most seriously affected countries by typhoons in the world. It is of great significance to study the influence of typhoon on landscape trees. At present, there were abundant research achievements on the prediction model and post- disaster statistical analysis of typhoon's impact on landscape trees at home and abroad. However, the research on the impacts of typhoon at the blowing moment on the landscape trees was less involved. Taking Houhai Campus of Shenzhen University as the research scope, this paper used Phoenics software to conduct CFD simulation to explore the impact of typhoon on landscape trees during the disaster. The study found that the distribution of damaged trees was consistent with that of wind speed. Wind speed, tree height and crown diameter were significantly correlated with the proportion of damaged trees.In view of the above research results, this paper put forward corresponding countermeasures and suggestions fro
