摘要：  2014年8月—2015年6月，对升金湖自然保护区维管植物进行了四季调查。分析结果显示，升金湖植物群落被划分为6个植被型，12个植被亚型，32个群系，主要群落类型有马尾松群丛（Ass. Pinus massoniana）、青冈栎群丛（Ass. Cyclobalanopsis glauca）、麻栎+枫香群丛（Ass. Quercus acutissima + Liquidambar formosana）、构骨冬青群丛（Ass. Ilex cornuta）、山胡椒群丛（Ass. Lindera glauca）、菰群丛（Ass. Zizania caduciflora）、陌上菅群丛（Ass. Carex thunbergii）、野菱群丛（Ass. Trapa maximowiczii）等。其中陌上菅群丛为沿岸滩涂的优势群丛，其株高、盖度、株数和生物量的数值在不同水深有明显不同，通过研究水深与陌上菅株高、盖度、株数、生物量关系，得出陌上菅的生物量和盖度与水深达到极显著相关关系(P<0.001），株数与水深显著相关(P<0.05)，而陌上菅的株高与水深关系不显著(P>0.05)。调查发现维管植物共125科335属510种，科可分为14个分布型，属可分为22个分布型。科和属的分布类型以世界分布型、泛热带分布型以及北温带分布型为主，热带性质较强，该区域植物区系特征为亚热带向暖温带过渡。结果可为升金湖的植被保护提供理论依据。

Abstract: The survey on the vascular plants in Shengjin Lake National Nature Reserve was done form August 2014 to June 2015. The community types were divided in to 6 vegetation types, 12 vegetation subtypes and 32 formations. The main community types were Ass. Pinus massoniana, Ass. Cyclobalanopsis glauca, Ass. Quercus acutissima + Liquidambar formosana, Ass.Ilex cornuta, Ass. Lindera glauca, Ass.Zizania caduciflora, Ass. Carex thunbergii, Ass. Trapa maximowiczii, and so on. Ass.Carex thunbergii was the advantage association of coastal tidal flats, the number, height, coverage, biomass of Carex thunbergii in different water depth were obviously different. Through analyzing the correlation between number, height, coverage, biomass of Carex thunbergii change with depth, it showed that the coverage and the biomass were highly significant correlation with the depth (P<0.001) and the number was significant correlation with the depth (P<0.05), but the height was not significant correlation with depth (P>0.05). There were 510 vascular plant species belonging to 335 genera in 125 families. 125 families were divided into 14 distribution types, and 335 genera were divided into 22 distribution types. The main distribution types were Cosmopolitan, Pantropic and North Temperate.
