摘　　要：通过对溆浦县森林、草原、湿地生态系统外来入侵植物调查,厘清溆浦县现有外来入侵植物种类与分布特征,为防治外来入侵植物提供科学依据。本研究以人工地面调查为主要方式,总计设置踏查点282个,踏查线路57条。结果表明:溆浦县有外来入侵植物22种,隶属于11科18属,其中菊科和苋科的种类最多。从生长型分析,除刺槐为乔木外,其余均为草本。从原产地分析,外来入侵植物主要来源于美洲地区,占比达70.6%。从分布方面分析,外来入侵植物较多的有大江口镇(11种)、祖师殿镇(9种)、深子湖镇(9种),物种数量最少的为黄茅园镇(2种),整体分布呈东多西少、北多南少的格局。从风险方面分析,高风险植物有7种,中风险植物有13种,低风险植物有2种。溆浦县外来入侵植物种类繁多,对本地生态系统具有一定的威胁。在后续工作中,应做好重点植物类群的防治工作,加强对外来入侵植物的科普宣传,并做好引种植物的风险评估工作。In order to clarify the species and distribution characteristics of existing invasive alien plants in Xupu County,and provide a scientific basis for the prevention and control of invasive alien plants,a survey of invasive alien plants in forest,grassland and wetland ecosystems was carried out in Xupu County.With artificial ground survey as the main method,a total of 282 inspection points and 57 inspection routes were set up.The results showed that a total of 22 species of invasive alien plants belonging to 18 genera and 11 families were found in Xupu County,among which Asteraceae and Amaranthaceae had the most species.In terms of growth type,except for Robinia pseudoacacia,which was arbor,the others were herbaceous.In terms of origin,invasive alien plants mainly originated from the Americas,accounting for 70.6%.In terms of distribution,there were more invasive alien plants in Dajiangkou Town(11 species),Zushidian Town(9 species)and Shenzihu Town(9 species),and Huangmaoyuan Town(2 species)with the lowest number.The overall distribution was more in the east and less in the west,and more in the north and less in the south.In terms of risk,there were 7 species of high-risk plants,13 species of medium-risk plants,and 2 species of low-risk plants.In general,there were many kinds of invasive alien plants in Xupu County,which posed a certain threat to the local ecosystem.In the process of follow-up work,it is necessary to do a good job in the prevention and control of key plant groups,strengthen the popularization of science on invasive alien plants,and do a good job in the risk assessment of introduced plants.
