摘要：植物多样性及其区系组成研究是反映区域生态系统结构及其生态状况的重要手段之一。以神农架大九湖湿地为研究对象,分析了其植物物种组成、优势植物种群及植物区系。结果表明:大九湖湿地维管束植物共52科140属201种,其中种子植物47科134属194种,外来入侵植物4科7属7种。草本植物群落类型主要以湿生植物群落为主,有苔草(Carex)群落、白车轴草(Trifolium repens)群落和地榆(Sanguisorba officinalis)群落等,占群落总数的59.60%。优势植物种有地榆(Sanguisorba officinalis)、阿齐苔草(Carex argyi)、灯心草(Juncus effusus)等,是组成该区域湿地植物群落的主要物种。植物区系主要有12个分布类型及4个变型,以温带分布为主,并含有一定的热带地理成分。
The study of plant diversity and its floristic composition is one of the important means to reflect the structure and ecological status of regional ecosystems.This paper takes the Shennongjia Dajiuhu wetlands as case study of plant species composition,dominant plant populations and flora.The results showed that there were a total of 201 species of wetland vascular plants belonging to 140 genera of 52 families in Dajiuhu wetlands,including 194 species of seed plants belonging to 134 genera of 47 families and 7 species of invasive plants belonging to 7 genera of 4 families.The types of herbaceous plant communities are mainly wet plant communities,including Carex community,Trifolium repens community,Sanguisorba officinalis community,which account for 59.60%of the total number of communities.The dominant plant species includes Sanguisorba officinalis,Carexargyi,Juncus effusus,etc.,which are the main species that constitute the wetland plant community in this area.The flora mainly contains 12 types and 4 sub-types of distribution,mainly temperate component and a certain quantity of tropical geographic component.
