摘要: 广东省现有外来入侵植物93种,隶属于27科72属,其中种类最多的菊科植物达21种,草本植物有81种,它们分别占广东省入侵植物总数的22.6%和87.1%。依据外来入侵植物目前在野外的生长和扩散状况等分析,发现其中危害严重的有24种,危害中等的有23种,危害较轻的有46种。广东省外来入侵植物中有76种来自于美洲地区,占入侵植物总数的81.7%。比较发现,广东与邻近的香港、厦门、广西在外来入侵植物的数量上以及在各自地区生物多样性造成严重危害的植物种类上比较接近,这可能是由于这些地区地理位置上相毗邻而利于物种之间的传播造成的。本文还提出了对广东省外来植物入侵防治策略。

Abstract: In Guangdong Province, there are 93 species of alien invasive plants, belonging to 27 families and 72 genera, of which, 21 species are of Asteraceae, and 81 species are herbal plants, accounting for 226% and 87.1% of the total, respectively. The analysis on their growth and dispersal status in the fields showed that 24 species were at high degree of threat to the local biodiversity, 23 species at medium degree, and 46 species at low degree. Among the 93 species of
alien invasive plants in Guangdong, 76 species were from America, accounting for81.7% of the total. The numbers  and the kinds of the alien invasive plants that cause severe threat to local biodiversity in Guangdong had lesser differences with those in the adjacent districts Hong Kong, Xiamen, and Guangxi, probably because the diffusion among the plant species induced by adjacent geographical location. Some management strategies of the alien invasive plants were suggested.
