采用路线调查、走访调查与样方调查相结合的方法,对澄碧湖景区外来入侵植物进行全面调查与分析,并探讨其入侵趋势与防治措施。结果表明,澄碧湖景区内共有21科33属42种外来入侵植物,其中69%为草本;种类最多的为菊科和苋科,共18种;来源于美洲的有36种,占总种数的85. 7%;另有57%作为观赏植物等有意引入。严重危害的共7种,为蟛蜞菊、飞机草、马缨丹、紫茉莉、假烟叶、五爪金龙、水花生。提高防御意识、加强生态保护、完善引种、健全监督机制是有效的防治途径。
A comprehensive survey and analysis of alien invasive plants at the scenic spot of Chengbi Lake was conducted by combining route investigation with interviews and quadrat sampling. There were 21 families,33 genera and 42 species in the scenic spot of Chengbi Lake. Among them,herbal plants accounted for 69%. The Compositae and Amaranthaceae families were the most frequent,represented by 18 species in total;36 species of these alien invasive plants originated from America,accounting for 85.7% of the total. Fifty-seven percent of the species were introduced as ornamental plants. Seven of them were severely harmful,including Wedelia trilobata,Eupatorium odoratum,Lantana camara,Mirabilis jalapa,Solanum erianthum,Ipomoea cairica and Alternanthera philoxeroides . Tactics to increase defensive awareness,reinforce ecological protection,regulate species introduction and improve supervision mechanisms are discussed.
