中国是世界上受到强、台风影响最大的国家,强台风除了会造成建筑物和桥梁的破坏、人员的伤亡外,还会导致树木被压弯甚至破坏。在海南省,每次登陆台风都会导致橡胶树林出现大量的根倒、弯曲和干折现象,可能造成数十亿元的经济损失,因此开展树木抗风的研究具有重要的意义。通过概述国内外对树林近地面风场及对风环境影响、树木的动力特性、风荷载计算及对树木风致响应的研究进展,并根据国内外研究现状及目前研究中存在的问题,提出了树木抗风及对风环境影响进一步研究的发展方向。
China is a country influenced most by strong winds and typhoons in the world. Strong winds not only damage buildings and bridges and cause casualties, but also make trees bend or even break. In Hainan Province, each typhoons will cause a large number of rubber trees to topple down, bend, and even break, which could cause economic losses up to billions of Yuan. Therefore, it is significant to conduct research on wind resistance of trees. This paper overviewed the research about the near-surface wind field of woods and its impact on wind environment in China and abroad, the dynamic characteristics of trees, the calculation of wind load, and the wind-induced re- sponse of trees. Based on the current research and existing problems, the direction for further research in wind-re- sistance of trees and its influence on the wind environment was proposed.
