摘要
A comprehensive survey and analysis of alien invasive plants at the scenic spot 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 Chengbi Lake.Among them,herbal plants accounted for 69%.The Compositae and Amaranthaceae families were the most frequent,represented by 18 species in total;and 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.Strategies to increase defensive awareness,reinforce ecological protection,regulate species introduction and improve supervision mechanisms are discussed.
