中文摘要 概述了近几十年来树木风振模型的发展,提出建立树冠、树干和树根三者结合的整体有限元模型,同时考虑其非线性效应是今后的研究方向,并且还需开展对树冠结构减振效应的量化研究,建立树干风振恢复力模型以及树木风振的随机振动模型。

英文摘要 This article summarizes the progress of the preceding decades for the wind-induced vibration model of trees.And future study should focus on: 1) the development of the finite element model of integrated crown structure,tree trunks and roots and the nonlinear effect as well at the same time;2) quantitative analysis of structural damping effect of the crown;and 3) the establishment of the restoring force model of trunks and stochastic vibration model of trees.This paper has an important theoretical and practical value in promoting the application of vibration theory in forestry and its development.
