摘  要：
2014—2016年通过野外实地调查,对茂兰喀斯特森林湿地水生植物物种的区系组成及多样性进行初步分析。结果表明,茂兰喀斯特森林湿地水生植物共有49科78属104种,其中蕨类植物6科6属8种,被子植物43科72属96种;优势科为禾本科(Gramineae)、菊科(Asteraceae)、眼子菜科(Potamogetonaceae)、蓼科(Polygonaceae)和莎草科(Cyperaceae)等;优势属为蓼属(Polygonum)、眼子菜属(Potamogeton)和莲子草属(Alternanthera)等,单属种占总属数的78.21%。茂兰喀斯特森林湿地水生植物区系组成较复杂,科、属、种分布类型呈现多样化;属在科中、种在属中、种在科中的分布均不均衡;单属科、单种属、单种科在数量上占优。茂兰喀斯特森林湿地水生植物地理区系组成特点为科的分布区类型主要是世界广布类型;属的分布区类型具有亚热带的特征;种的分布类型以温带分布种居多,其次是热带分布种,世界广布种相对较少。

摘  要：
The floristic composition and diversity of aquatic plant species in Maolan Karst Forest Wetland were preliminarily analyzed based on the field survey from 2014 to 2016. The results indicated that there were 104 species of aquatic plants belonging to 78 genera and 49 families in Maolan Karst Forest Wetland, of which ferns belonged to 6 families, 6 genera and 8 species and angiosperms belonged to 43 families, 72 genera and96 species. Gramineae, Asteraceae, Potamogetonaceae, Polygonaceae, and Cyperaceae were the dominant families and Polygonum, Potamogeton, and Alternanthera were the preponderant genera, in which the single species accounted for 78.21% of the total genera. The floristic composition of aquatic plants in Maolan Karst Forest Wetland is rather complicated and the reasons are: the distribution types of families, genera and species are diversified; the distribution of genera in families, species in genera and species in families are unbalanced;and the single-species, monotypic and single-species families are dominant in number. The composition of the floristic region of Maolan Karst Forest Wetland includes the following points: families are mainly the widespread distribution types; the distribution types of genera shows subtropical characteristics; and the distribution types of species are mostly temperate distribution species, followed by tropical species and relatively few widespread distribution types.
