| 摘 要： | 为掌握北京地区湿地维管束植物外来种的多样性特征及群落构成和分布,采用样带和样方相结合的方法,参考相关资料,从北京市湿地植物中筛选出归化种和入侵种,分析其数量和出现频率;计算外来种的重要值,分析其群落组成;根据实地调查数据分析外来种的群落分布特征。共筛选出外来种19种,其中通奶草、豆瓣菜、野牛草等6种植物为归化种,反枝苋、小蓬草、豚草等13种植物对湿地生境、农作物或当地人畜造成危害,为入侵种;外来种中湿生或水生植物所占比例小,说明了水资源缺乏导致的湿地退化是生物入侵的重要原因之一。最后,对入侵种造成的危害及防治方法进行了论述。

| Abstract: | In order to make clear diversity and community structure and distribution of alien plants in wetlands of Beijing, we screened naturalized species and invasive species from wetland vascular plants in Beijing with combined methods of transects quadrats and literature review. Quantities, frequencies and importance values were analyzed for community composition and distribution according to field investigation data. A total of 19 alien wetland vascular plant species were found in Beijing in which Euphorbia indi... |
