摘 要:
通过对鹦哥岭外来植物的调查,以及外来植物区系的种类组成、原产地、生长型、生境和危害程度等的分析,阐明鹦哥岭的外来植物现状及其对当地生态环境的影响。分析表明:共有53种外来植物,约占鹦哥岭种子植物总数的2.73%,主要来自新大陆热带地区(35种)。其中草本(36种)和灌木(13种)占优势,藤本(3种)和小乔木(2种)相对不明显。外来种对鹦哥岭自然生态系统的影响较小,对人为干扰严重的生态系统影响较大。最后对外来植物进行评估,并提出防控措施。[著者文摘]

Abstract:
We used extensive fieldwork as the basis for a study of the alien plants of Yinggeling, Hainan Island. In total, 53 alien plants species were recognized, making up 3% of the flora, in which, the tropical elements of the New World predominated, with 35 species making up 60% of the alien flora. Herbs (36 species) and shrubs (13 species) predominated relative to the climbers (3 species) and small trees (2 species). The composition, origin, growth form and habitat of alien plants were discussed in order to show the status and the influence to the environment. It shows that it is more serious in disturbed ecosystem than in natural ecosystem. And the influence were evaluated, with suggestions for controlling invasion.[著者文摘]
