基于野外调查、标本鉴定和文献查阅，对怀化市外来入侵植物的物种组成、生活型、危害等级和分布范围等现状进行了调查。结果显示：怀化市共有外来入侵植物26科47属64种(不含栽培种)，以菊科(Asteraceae)、苋科(Amaranthaceae)和茄科(Solanaceae)植物为主，分别有18、8和6种；生活型以草本占绝对优势(61种)；原产地以北美洲和南美洲为主(30种)；恶意入侵4种，严重入侵9种，局部入侵和一般入侵共43种，有待观察8种，其中，喜旱莲子草〔Alternanthera philoxeroides (Mart.) Griseb.〕等4种恶意入侵植物在各乡(镇)均有分布。整体上看，怀化市外来入侵植物种类较多、生境复杂，在城镇周边及道路旁等人类活动频繁区适应性强、繁殖速度快。可通过减少外来植物引种和加强乡土物种选育等手段进行防控。

Based on field surveys, specimen identification, and literature review, the current status of species composition, life forms, harm levels, and distribution range of  alien invasive plants in Huaihua City was investigated. The results show that there are 64 species (excluding cultivated species) of  alien invasive plants in Huaihua City, belonging to 47 genera of 26 families, and Asteraceae, Amaranthaceae, and Solanaceae are the dominant families, which contain 18, 8, and 6 species, respectively; in terms of life forms, herb is absolutely dominant (61 species); the origins are mainly North America and South America (30 species); there are 4 species of malicious invasion, 9 species of severe invasion, 43 species of local invasion or general invasion, and 8 species of requiring further observation class, among which, 4 malicious invasion species such as Alternanthera philoxeroides (Mart.) Griseb. are distributed in each township (town). Overall, Huaihua City has many species of alien invasive plants with complex habitats, and these plants exhibit strong adaptability and rapid reproduction rates in areas with frequent human activities, such as around towns and along roadsides. Prevention and control can be implemented by reducing the introduction of alien plants and strengthening the selection and breeding of native species, etc.
