摘要
2010-2018年,通过对9个监测点的野外调查和复查,对杭州西溪国家湿地公园(西溪湿地)的野生维管植物的生活型、珍稀濒危植物和外来入侵植物及植物区系情况进行了研究。结果表明,西溪湿地分布野生维管植物有94科270属424种;共记录到4种国家二级重点保护野生植物,分别为金荞麦Fagopyrum dibotrys,樟Cinnamomum camphora,野大豆Glycine soja和四角刻叶菱Trapa incisa;外来入侵植物有28种,隶属于13科22属;西溪湿地植物可分为乔木、灌木、藤本、草本4种生活型,以草本植物占优势。对表征科及属的地理分布进行分析,结果表明,温带成分与热带成分之间没有显著差异,体现了热带向温带过渡的特征;植物区系有一定的复杂性和古老性,与日本植物区系关系较密切;分布有中国特有植物1属,为皿果草属Omphalotrigonotis。
Background survey was implemented in 2003 in Xixi National Wetland Park of Hangzhou,Zhejiang province.During 2010 and 2018,field investigations on wild vascular plants,rare and endangered plant and alien invasive plants had been carried out in 4 seasons each year.The result demonstrated that there were 424 species,belonging to 94 families and 270 genera of wild vascular plant in the park,among them,4 species were under national second-class protection,namely Fagopyrum dibotrys,Cinnamomum camphora,Glycine soj and Trapa incise.There were alien invasive plants of 28 species,belonging to 13 families 22 genera.92 species of woody plant occupied 21.7%of the total one in the park,and 332 species of herb took 78.3 of the total one.Flora analysis indicated that there had no significant difference between temporary and tropical component of typical families and genera,indicating transitional characteristic.The analysis resulted that the flora was complex and old,having a close relationship with Japanese flora.One Chinese endemic genus of Omphalotrigonotis,was recorded.
