北京翠湖湿地维管束植物多样性及保护对策

结合北京地区湿地植物相关研究和翠湖湿地维管束植物调查结果,对翠湖湿地的维管束植物进行分类、整理和分析。结果显示:翠湖湿地有维管束植物306种,隶属76科228属,占北京市维管束植物总数的17.1%。翠湖湿地分布有多种国家级和北京市级重点保护野生植物,如野大豆Glycine soja、芡实Euryale ferox、茭白Zizania latifolia、花蔺Butomus umbellatus等。翠湖湿地还统计到外来和入侵植物共计13种,如豚草Ambrosia artemisiifolia、凤眼莲Eichhornia crassipes等。翠湖湿地维管束植物多样性丰富,需加强植物多样性保护和管理以及科普教育。

Diversity of Vascular Plants in Cuihu Wetland in Beijing and Its Conservation

Based on a survey of vascular plants in Cuihu Wetland and relevant studies of wetland plants in Beijing area,the vascular plants in Cuihu Wetland were classified,documented and analyzed.Results showed that there were 306 species of vascular plants in Cuihu Wetland,belonging to 76 families and 228 genera,accounting for 17.1% of the total number of vascular plants in Beijing.A variety of wild plants with national and municipal priorities for protection were found in the wetland,e.g.Glycine Soja,Euryale ferox,Zizania latifolia and Butomus umbellatus.13 species of invasive alien plants were found in the wetland,e.g.Ambrosia artemisiifolia and Eichhornia crassipes.Growing in the wetland,there were 11 species which are the most typical wetland plants in Beijing,However,other 3 typical wetland plant species of Potamogeton pectinatus,Potamogeton panormitanus and Fimbristylis bisumbellata were not found in the wetland.The diversity of vascular plants in Cuihu Wetland is rich.Conservation and management of plant diversity and science education need to be further strengthened.
