| 摘 要： | 作为具有生态价值、经济价值和文化价值等多重价值的生物载体，树木是一种重要的自然资源。自然界中树木的生长、生存始终面临着各种威胁和挑战，其中最大、最不可控的危险因素是风。过高的风载荷可能导致树木整体倾斜、树干弯曲、枝叶折断、折干倒伏以及掘根倒伏等形式的破坏，从而带来严重的生态、经济和文化等方面的损失，而且可能危及人们的生命财产安全。为了保护树木、减少损失，文中对树木风载及其安全性评估的研究进展进行综述。介绍独立树木、林缘树木和林内树木的树木风载荷计算方法；阐述树木折干倒伏和掘根倒伏的安全性检测和评估的研究进展，总结现有评价模型的表现和效果，并概述树木动态响应的影响；提出目前研究中存在的问题，并对未来发展进行展望。

| Abstract: | As a biological carrier with multiple ecological, economic and cultural values, trees are a kind of important natural resource. During the growth and survival in the nature, trees are confronted with various threats and challenges, among which wind is the most significant and uncontrollable risk. High wind loads may cause the leaning, bending, breaking and uprooting of trees, which not only cause serious ecological, economic and cultural losses but also threaten people's lives and property. This paper reviews the research progress in wind loading of tree and tree safety assessment, with the aim to protect trees and reduce losses. Firstly, the calculation methods for wind loads of single trees, trees at forest edges and trees within forests are introduced, respectively. Then, the research progress in the safety detection and assessment of lodging and uprooting is elaborated, the performance and effectiveness of existing evaluation models are summarized, and the impact of tree dynamic response is introduced. In the end, the problems rising in the current research are identified, and the future research directions are prospected. |
