摘　　要：经调查发现,漩门湾湿地的外来入侵植物有17科35属43种,其中以菊科最多,达14种,占32. 6%;生活型则以1年生、2年生草本植物为主。分析漩门湾湿地入侵植物的入侵性与实际危害程度,在漩门湾湿地危害严重且分布广泛的外来入侵植物有喜旱莲子草、一年蓬、小飞蓬、苏门白酒草、加拿大一枝黄花、藿香蓟、钻形紫菀等7种。研究外来植物入侵漩门湾湿地的入侵途径与入侵后果,指出外来植物入侵漩门湾湿地以无意引入和自然扩散为主,湿地受外来植物入侵的影响与隐患主要体现在生态威胁、生产影响、景观破坏等3个方面,并提出了管控漩门湾湿地外来入侵植物的相应对策。Based on a field survey,43 species alien invasive plants,belonging to 35 genera and 17 families are found in Xuanmen Bay wetland.Compositae was the most common family,consisting of 14 species,accounting for 32.6%of all invasive species.Among the life forms of these plants,annual and biennial herbaceous plants were the most abundant.The invasiveness and actual damage inflicted by invasive plants in Xuanmen Bay wetland were analyzed.Seven species,Alternanthera philoxeroides,Erigeron annuus,Conyza canadensis,Conyza sumatrensis,Solidago canadensis,Ageratum conyzoides and Aster subulatus were widely distributed and seriously damage Xuanmen Bay wetland.The invasion and consequences of invasive plants were studied.Wetland invasion was mostly from unintentional introductions and further natural dissemination.The impacts and hidden dangers of alien invasive plants were mainly reflected in 3 aspects:ecological threat,production impact and landscape destruction.The control measures for alien invasive plants in Xuanmen Bay wetland are discussed.
