摘　　要：为了解台风对博白林场不同树种的为害情况及其影响因子,对台风“彩虹”对不同林分位置的39个树种168株树木的受害情况进行了调查。结果表明:(1)不同树种受害情况存在较大差异,针叶树种受害明显轻于阔叶树种;(2)树木的受害情况与其胸径、树高、枝下高、冠幅关系密切,胸径较小、树高较高、枝下高较大、冠幅较大的树木受害较严重;(3)林内的树木受害明显轻于林窗和开阔地的树木,林缘迎风面树木的受害远重于林缘背风面的树木。To explore the damage of typhoons to the different tree species & its influencing factors, the damage of 168 trees from 39 tree species of different forest sites by typhoon “rainbow” at Bobai Forest Farm were investigated.Result shows that:(1) There is the lower damage to coniferous tree species than the broadleaf tree species;(2) The lower DBH, the higher height, the higher clear bole height & the bigger crown breadth could lead to the bigger damage to the tree under the typhoons;(3) There is bigger damage to the trees in the stand than that to the trees in the gap & in the open ground, and there are bigger damage to the trees in the windward side of forest edge than the trees in the leeside.
