摘要
为了摸清平塘县森林、草原、湿地三大生态系统外来入侵植物本底,本研究采用踏查、访问调查、样地调查等方法对平塘县森林、草原、湿地三大生态系统进行外来入侵植物现状调查.调查发现:(1)平塘县森林、草原、湿地三大生态系统共有外来入侵植物94种,隶属于32科65属.其中数量最多的为菊科,共24种,占总种数的25.53％;其次为豆科,共12种,占总种数的12.77％;茄科和苋科各7种,均分别占总种数的7.45％.(2)一年生草本植物有40种,占总入侵植物数量的42.55％;多年生草本植物有37种,占总入侵植物数量的39.36％;藤本植物2种,占总数的2.13％;木本植物15种,占总数的15.96％.(3)平塘县入侵植物原产地为美洲地区的共66种,占外来入侵植物总数的70.21％;其次是原产地为欧洲的植物12种,占总数的12.77％;原产地为非洲的有9种,占总数的9.57％;原产地为亚洲的有4种,占总数的4.26％;原产地为大洋洲(澳大利亚)的有3种,占总数的3.19％.
Abstract
In order to explore the background of invasive plants in the forests,grasslands and wetlands in Pingtang County,we investigated the status of invasive plants in the forests,grasslands and wetlands in Pingtang County by u-sing the methods of field survey,interview and sample plot survey.The results were as follows:(1)There were 94 species of invasive plants in Pingtang County,belonging to 65 genera and 32 families.Among them,Asteraceae had the largest number of species(24),accounting for 25.53％of the total number of species,followed by Leguminosae(12),accounting for 12.77％of the total number of species.There were 7 species of Solanaceae and Amaranthace-ae,respectively,each accounting for 7.45％of the total number of species.(2)There were 40 species of annual herbs,accounting for 42.55％of the total number of invasive plants;37 species of perennial herbs,accounting for 39.36％;2 species of lianas,accounting for 2.13％;and 15 species of woody plants,accounting for 15.96％.(3)66 species originated from America,accounting for 70.21％of the total number of invasive plants;12 species origi-nated from Europe,accounting for 12.77％;9 species originated from Africa,accounting for 9.57％;4 species origi-nated from Asia,accounting for 4.26％;3 species originated from Australia,accounting for 3.19％.
