摘　　要：根据有关调查资料,对河南省湿地植被特征种的区系组成、科属种三级分布区类型及其与植被的关系等进行了分析,阐述了河南省湿地植被的特征。结果显示,维管植物有50科99属249种,种子植物科的分布区类型有6个,属有10个,种有13个。科属都为世界分布类型最多,除此类型之外,泛热带和北温带成分占有突出的位置。种分布区类型中,世界分布显著减少,而以东亚分布为最多,热带亚洲分布次之,北温带分布居第三;中国特有分布中,中国亚热带分布为最多。从浅水湿地到草丛湿地植被,其建群种虽都以世界分布科为最多,但热带分布数量减少,而温带分布数量逐渐增多。河南省湿地植物区系与东亚和热带亚洲以及北温带的植物区系联系最为紧密,而在中国南北方湿地植被的区系关系中较接近于南方亚热带的湿地植被区系特征。Henan province is located in central-eastern China,in the south part of North China Plain and on the east end of Qinling Mountain remaining vein,between 110°21＇-116°39＇E and 31°23＇-36°22＇N,covering an area of 16.7×10 4km 2,of which wetland 105×10 4hm 2 （about 6.3% of the total land area） in 2007.Its pure natural wetland vegetation can be classified as 50 formations in 8 vegetation types of 4 vegetation type groups （broad leaved forest,scrub,herbosa,and aquatic plant wetland vegetations）.The so-called ＂characteristic species of wetland vegetation＂ refers to the plants which appear only or mainly in the natural wetland vegetation.Being the inherent component of wetland vegetation,this kind of plants can best reflect the essential characteristics of wetland vegetation,with indication function.Therefore,floristic study of the characteristic species of the wetland vegetation is of importance in revealing the essential property of the wetland vegetation in this paticular region.Based on the investigation data,the characteristic species of wetland vegetation in Henan province are presented and their floristic characteristics are analyzed from three levels （the family,genus and species） in this paper.The results showed there were 249 characteristic species in 99 genera of 50 families belonging to vascular plants.The spermatophytes of those plants can be divided into 6 distribution types at family level,10 at generic level and 13 at species level,respectively.The families and the genera of Cosmopolitan type are majority,after that,the Pantropic and the North Temperate types are conspicuous ones.The species belonging to the East Asian type are the most common,the Tropical Asian type the second,and the North Temperate type the third.Among the species endemic to China,those distributed in the subtropical area are the greatest in number,those spreading from subtropics to temperate zone the second,and those in temperate zone the third.From aquatic vegetation to grass wetland vegetation,though the
