摘　　要：以冷害评级标准对广州市常见热带引种园林植物的2008年春低温冷害情况进行调查评价。结果表明,在广州地区,23种常见园林植物受害等级在1～5之间,尤其塞楝、马占相思、凤凰木以及棕榈科植物更为严重,植物的受害程度还与生境等因素有关。针对冷害的特点和原因,对广州市园林植物防寒和引种提出几点建议。The tropical botanical garden planls in Guangzhou were chosen to study the impact of low temperature caused by the snow and ice disaster in 2008. The damage of these plants was graded to 5. The study indicated the damage grade of 23 kinds of the common ornamental plants varied from 1 to 5, among which Khaya senegalensis （Desr.） A. Juss, Acacia rnangium, DeloniJc regia （Boj.） Raf and the palm plant were especially damaged. Such damage was also related to their habitat and some other environmental factors. In view of the characteristics of cold disaster, some proposals were put forward for the improvement of cold-resistance of ornamental plants.
