摘 要 ：通过调查和文献整理，初步确认广西有外来入侵植物114种，隶属于36科80属，其中以菊科的种类最多，有26种。从来源看，外来入侵植物来源于世界各地，以来源于美洲居多，有87种，占76.3%。入侵植物以草本植物为主，有90种，占78.9%。外来入侵植物主要通过有意引入和无意传入等方式入侵广西。它们的入侵，特别是一些恶性杂草的入侵，给广西农业、林业、人类健康以及生态环境带来巨大的负面影响。加强对外来入侵植物的调查和评估，恢复当地植被和物种的多样性，开展有害生物风险分析是防范外来入侵植物的有效途径。

Abstract:There are 114 species of invasive plants belonging to 80 genera, 36 families in Guangxi Province. The most abundant family is Compositae including 26 species. The plants all immigrated from aboard and 87 species (76.3%) are mainly from America. There are 90 species of Herbs amounting to 78.9% of the total species. The plants were introduced intentionally or unconsciously. They, especially poisonous or virulent weeds, have produced large negative effects on agriculture, forestry, human health and ecological environment in Guangxi. The effective approaches to defend against invasive plants are as follows: to investigate and evaluate invasive species, to recover native vegetation and species diversity, to implement risk analysis of invasive plants.
