摘要:
对国内原产地的金钟藤进行初步调查,发现该种在海南岛分布广泛,并对该岛中部山区的中低海拔次生林和人工残次林造成严重危害;而在云南、广西等省区虽有分布,但危害较轻。根据对金钟藤生物生态学特性的分析,结合其在新旧分布地的现状,认为该种为典型的生态危害种,具有很强的潜在入侵能力,对其防治应以综合防治为主。

Abstract:
Merremia boisiana (Gagn.) v. Ooststr, an aggressive woody twiner that invades lowland forest habitats, is a member of the Convolvulaceae commonly called Jinzhongteng (FOC). From the investigation in its original habitats, it is found that this species has done serious damage to the middle and low–altitude mountain secondary forest and artificial secondary forest in Hainan Island, but less impairment in Yunnan province and Guangxi province. Based on analysis on ecological and biological characteristics and expressivities of M. boisiana in original and current distribution areas in China, this paper has proposed that the species is a typical ecological–hazard invasive plant, and comprehensive preventive measures should be put into force immediately.
Key words:  Merremia boisiana, Hainan Island, damage and prevention
