Plant Diversity and Formationin Mochou Lake National Wetland Park in Zhongxiang

湿地公园是中国自然保护地体系的重要组成部分,其植物多样性及主要群系组成可以为湿地公园的建设与管理提供重要理论依据。本研究通过样方调查法,研究了湖北省钟祥市莫愁湖国家湿地公园的植物多样性与主要植物群系类型。结果表明:钟祥市莫愁湖国家湿地公园内共计调查到维管束植物139科357属510种;可被分为2个植被型组3个植被型10个群系。湿地公园内主要分布10种植物群系,分别为:菱群系、芦苇群系、莲群系、菰群系、喜旱莲子草群系、美人蕉群系、香蒲群系、金鸡菊群系、意大利214杨群系、狗尾草群系。湿地公园内分布有外来入侵种凤眼蓝和喜旱莲子草。该研究结果可为莫愁湖国家湿地公园的建设与管理提供科学依据。

Wetland parks are an important part of national nature reserve system,and its diversity and main formation composition of National Wetland Park can provide an important theoretical basis for construction and management of wetland parks.In this paper,the plant diversity and main plant community types of Mochou Lake National Wetland Park in Zhongxiang City,Hubei Province were studied by the method of quadratic survey.The results showed that 510 species of vascular plants belonging to 357 genera and 139 families were investigated in Mochu Lake National Wetland Park in Zhongxiang City,which were divided into 2 vegetation types,3 vegetation types and 10 floras.There were 10 main floras distributed in the wetland park,which were Form.Trapa bispinosa,Form.Phragmites australis,Form.Nymphaea nucifera,Form.Zizania latifolia,Form.Alternanthera philoxeroides,Form.Canna indica,Form.Typha orientalis,Form.Coreopsis drummondii,Form.Populus×canadensis‘I-214’,Form.Setaria viridis.Two invasive species in the wetland park including Eichhornia crassipes and Alternanthera philoxeroides.The research results can provide a scientific basis for the construction and management of Mochou Lake National Wetland Park.
