摘要
通过实地考察和标本的研究鉴定,衡水湖湿地被子植物共有55科、166属、271种(含种下等级).本区被子植物生活型以地面芽植物和一年生植物占优势,生态类型以旱生植物为主,占总种数的39%;属的区系成分中,温带成分属最多,占总数的53%;其次是世界分布类型属,占总数的28%,表明了该区系显著的温带性质.衡水湖湿地植物群落类型丰富但物种组成较少;植物群落呈现明显的成带性分布特征.
An investigation was conducted in Hengshui Lake Wetland. There are 55 families, 166 genera, 271 species （contain under species unit） of Angiospermae flora. The dominate Life Form types of Angiospermae were Geophytes and Therophytes. The ecotypes mainly consis to fxero-phytes, which accounts for 39% of all the species. The areal-type of the genus of Pteridophyte in this florar effects the distinctive temperate trait, Temperate type takes the large proportion of the florar which accounts for 53%, The following is Cosmopolitans type, which accounts for 28%. Plant Community types in Hengshui Lake Wetland are diversity, but Species Composition of them are lower diversity, Distribution regularity of Plant Community is the line distribution in changing hypsography parts.
