摘要
基于国内外文献资料、标本信息和野外调查,初步整理了浙江省外来入侵植物的种类组成、生活型、原产地、危害程度和入侵途径。结果表明,浙江省现有外来入侵植物46科106属166种,种数最多的是菊科、豆科和禾本科。根据原产地分析,来源于南美洲的物种最多,约占总数的32.16%,其次为北美洲,约占总数的25.63%,欧洲排第三位,约占总数的19.59%;已产生严重危害的有23种,中等危害的60种,危害较轻的83种。还有一些物种虽然没有在表里列出,但它们具有潜在的危害,必须密切关注。同时,与之前的研究相比,我们去除了一些已报道为入侵的物种,又增加了一些新的入侵种。在此基础上,对浙江省外来入侵植物的生活型、来源及危害进行了分析,并与以往的研究进行了比较,提出了针对性的管理建议。
An analysis of relevant literature and specimen records was conducted, together with field investigations, to examine the species composition, life form, origin, harmfulness and form of introduction of alien invasive plants in Zhejiang Province, China. A total of 166 alien invasive plant species belonging to 106 genera and 46 families were identified. The most common families represented were Asteraceae, Leguminosae and Gramineae, while the most common places of origin were South America, accounting for 32. 16% of all species, followed by North America （ 25.63%0 ） and Europe （ 19.59% ）. Twenty-three of the species were considered to cause high levels of damage, 60 medium levels of damage, and 83 low or minimal damage. Based on our records, we removed some invasive species from existing lists and added some new ones. Several suggestions for the management of invasive plants in Zhejiang Province are presented.
