摘要
本文研究了安徽省水生高等植物资源的种类、生境、组成特点、经济价值及植被概况,结果表明本省有水生高等植物44科、72属、138种,其中单子叶植物占优势,分别占科、属、种的40.9%、50.0%、54.4%。各科亲缘关系较远,并且许多科仅有一属的少数种为水生的。其地理成分表明,本地水生种子植物以世界分布属为主,热带成分与温带成分几乎各占一半,基本反映安徽省具有热带和温带的双重性质。水生植被以竹叶眼子菜(Potamogetonmalaianus)群落,苦草(Vallisineriaspiralis)群落,紫萍(Spirodelapolyrrhiza)、浮萍(Lemnaminor)群落,满江红(Azollaimbricata)、槐叶苹(Salvinianatans)群落,莲(Nelumbonucifera)群落为主。
The aquatic higher plants and their habitat, nature, economic value and vegetation features are analyzed in this paper. The results show that there are 44 families, 72 genera and 138 species in Anhui, dominated by Monocots, which make up 40.9%, 50.0%, 54.4% in families, genera and species respectively. Moreover, they haven't close relationships among families, many of which are families with only one genus of aquatic plants. The floristic connection with another ones of the world is wide, with cosmopolitan takeing a predominant position. The fact that tropical and temperate elements nearly occupy a half shows the dual nature of tropical and temperate in Anhui. The main vegetations are dominated by the populations of Potamogeton malaianus, Vallisineria spiralis, Spirodela polyrhiza, Lemna minor, Azolla imbricate, Salvinia natans, Nelumbo nucifera et al.
