国家湿地公园是自然保护体系重要部分,研究国家湿地公园植物多样性及植物群落可以为湿地公园的建设和管理和生物多样性保护具有重要意义。本文通过样方调查法,研究了杜公湖国家湿地公园的植物多样性及主要植物群落,主要结果如下:(1)武汉杜公湖国家湿地公园内的维管束植物有64科146属177种;(2)湿地公园植被可划分为2个植被型组,5个植被型和19个植物群系;(3)湿地公园内共分布有10个主要植物群落,分别为芦苇群落、穗状狐尾藻群落、慈竹群落、莲群落、加杨群落、决明群落、侧柏群落、池杉群落、鸡爪槭群落和构树群落。外来入侵种为凤眼蓝和喜旱莲子草。该研究成果可为武汉杜公湖国家湿地公园的保护与管理提供重要的科学依据。

National wetland park is an important part of national natural conservation system.The study of plant diversity and plant communities in national wetland parks is of great significance for the protection of biodiversity and the construction and management of wetland parks.In this paper,we investigated plant diversity and main plant community type of Dugonghu National Wetland Park.The main results are as follows:(1)There were 177 species of 146 genera in 64 families;(2)The vegetation of wetland park could be divided into 2 vegetation type groups,5 vegetation types and 19 flora;(3)there were 10 main plant community types distributed in the wetland park,which were Form.Phragmites australis,Form.Myriophyllum spicatum,Form.Bambusa emeiensis,Form.Nelumbo nucifera,Form.Populus×canadensis,Form.Senna tora,Form.Platycladus orientalis,Form.Taxodium distichum,Form.Acer palmatum and Form.Broussonetia papyrifera.Also,tow invasive species including Eichhornia crassipes and Alternanthera philoxeroideswere found in this national wetland park.The research results can provide an important scientific basis for the protection and management of Wuhan Dugonghu National Wetland Park.
