摘　　要：应用双向指示种(TWINSPAN)分类和主成分分析(PCR)技术对平天湖湿地植物多样性进行研究,并对其植物群落的30个样方进行分类排序.结果表明:平天湖湿地种子植物区系中,区域特色性不很明显,温带地理成分和热带地理成分相当,分别占30.87%和35.03%,与该地所处的北亚热带温润性季风气候相一致.平天湖湿地群落可划分为"水生植物群落"、"沼生植物群落"和"中生植物群落"三大类型,其维管植物中,中生植物有79科150属183种,沼生植物有8科11属26种,水生植物有12科13属15种.30个样方排序可划分为6个群丛类型.为了平天湖湿地的可持续发展,文中提出了相应的建设措施.Species diversity and classification and ordination of plant community in Pingtian Lake wetland were studied using TWINSPAN and PCA methods. The results showed that the regional characteristics of the floristic composition was not obvious in Pingtian Lake wetland. The ratio of R/T was almost the same, with 35.03 % temperate elements and 30.87% tropical elements, which was correlated with the subtropical moist monsoon climate The plant community can be categorized into three community types, i. e. me^phytic plant communities, wetland plant communities and aquatic plant communities. There were 183 mesophytic species which belonged to 79 families and 150 genera, 26 wetland species which belonged to 8 families and 11 genera, as well as 15 aquatic species which belonged to 12 families and 13 genera in the 224 vascular plants. The 30 samples can be divided into 6 associations. Some constructive suggestions were proposed for the sustainable management of Pingtian Lake wetland.
