【摘要】 基于文献报道、野外调查、标本记录和必要的分类学考证,整理出我国外来入侵植物72科285属515种。根据外来入侵种的生物学与生态学特性、自然地理分布、入侵范围以及所产生的危害,将其划分为5类:即恶性入侵类(34种)、严重入侵类(69种)、局部入侵类(85种)、一般入侵类(80种)和有待观察类(247种)。通过地理分布格局分析,中国外来入侵植物主要分布在我国西南及东部沿海地区,并进一步扩散到内陆各省。中国外来入侵等级划分和地理分布格局可以作为外来入侵植物风险防范和管理的依据。本工作提供我国外来入侵植物的本底资料的同时,还对主要外来入侵植物的管理提出了具体建议。更多还原

【Abstract】 We used the literature, field investigations, specimen records and taxonomic research to categorize 515 alien invasive plant species from 72 families and 285 genera reported from China according to their biological and ecological characters, extent of spread within China, and amount of damage caused. Each species was put into one of 5 categories: malignant invasion(34 species), serious invasion(69 species), local invasion(85 species), general invasion(80 species), and species requiring further observation(247 species). According to our analyses of geographic distributional patterns, Chinese alien invasive plants were highly con-centrated in the southwestern and eastern coastal provinces of China, and were rapidly spreading to inland China. These categories and distributional patterns of alien invasive plants could help to assess and control their invasive risk. Our results provide baseline information on Chinese alien invasive plants; and, at the same time, we put forward preliminary suggestions for further study, public education and the management of the important alien invasive plants in China.更多还原
