通过对气候相似的中国和美国的入侵植物进行比较分析，揭示了它们在分类特征、形态特征、原产地、入侵地区和引种历史等方面的异同。总体而言，菊科和禾本科的入侵种较多，且只有一种入侵种的科所占比例较高。大多数入侵者至少有一种生殖方式，有性生殖是主要方式，以及适应花，果实和种子的特性，成功的种子生产和传播。许多入侵植物能够进行无性繁殖。对中国和美国的外来入侵物种分析表明，它们主要来自与入侵地气候相似或纬度相同的大陆。热带地区的物种比其他气候带的物种更容易入侵。我们对引入中国和美国的物种的入侵历史的研究表明，外来物种成为入侵物种大约需要100年的时间。(C)2018作者由爱思唯尔公司出版
A comparative analysis of invasive plants in China and the USA, the climates of which are similar, revealed both similarities and differences in taxonomic characteristics, morphological characteristics, areas of origin, invaded regions, and histories of introduction. Generally, there were more species from Asteraceae and Poaceae than from other families, and a high proportion of families were represented by only one invasive species. Most invaders had at least one reproductive mode, with sexual reproduction being the main mode, as well as the adaptation of flower, fruit, and seed characteristics for successful seed production and dispersal. Many invasive plants are able to reproduce clonally. An analysis of the invasive species in China and the USA indicated that they are mainly derived from continents with climates similar to that of the invaded area or at latitudes within the same range. Species from tropical areas invaded more easily than those from other climatic zones. Our study of the invasive histories of species introduced into China and the USA demonstrates that it takes about 100 years for an exotic species to become an invasive species. (C) 2018 The Authors.
