福建农林大学金山校园外来入侵植物种类初步调查

Investigation of alien invasive plants in the Jinshan Campus of Fujian Agriculture and Forestry University

为了解福建农林大学金山校区外来入侵植物现状,通过实地调查和资料查阅,对校园内外来入侵植物的种类组成、原产地、生活型、危害程度(入侵等级)等特性进行了研究和分析。结果表明,福建农林大学校园共有外来入侵植物68种,隶属26科,以菊科、豆科、苋科植物总类最多,3科合计占外来入侵植物总数的58.82%;生活型以草本植物为主,有60种,占比高达88.24%;从来源来看,大多来自美洲,达54种,占79.41%;从水平分布来看,主要分布在长期缺乏人员管理的区域;入侵等级以恶性入侵类和局部入侵类植物占比最高,占外来入侵植物总数的52.94%。为了防止外来入侵植物对校园内生态环境造成重大危害,应及时开展外来入侵植物动态监测与评估等工作。

To better understand the current situation regarding alien invasive plants in the Jinshan Campus of Fujian Agriculture and Forestry University,the species composition,origins,plant types,degree of harm(invasive grade),and other characteristics of alien invasive plants were studied and analyzed through a field investigation and data review.68 invasive species belonging to 26 families were found.Compositae,Leguminosae,and Amaranthaceae were the dominant families,accounting for 58.82% of the total number of alien invasive plants.The plant type was mainly herbaceous(60 species),accounting for 88.24% of the total invasive species.The largest number of alien invasive plants originated from America(54 species),accounting for 79.41% of all alien invasive plants.Horizontal distribution data indicated distribution of invasive plants mainly in areas with a long-term lack of personnel management.The invasive grade comprised the highest proportion of malignant and local invasive plants,accounting for 52.94% of the total number of alien invasive plants.To prevent invasive plants from harming the ecological environment of the campus,dynamic monitoring and evaluation of invasive plants should be carried with time.
