摘要：植物功能性状研究在生态系统演替以及生态系统对环境变化的响应中具有重要意义。分析江苏盐城滨海湿地优势植物密度、植株高度、叶面积指数、叶片长宽比、单叶重、叶绿素含量、茎粗、单位面积生物量功能性状,结果表明:不同植物的功能性状存在着显著差异,其中,碱蓬植株密度最大,荻最小;芦苇植株高度最高,碱蓬最低;荻叶面积指数最大,互花米草叶面积指数与白茅、芦苇的相近;互花米草叶绿素含量最高,白茅最低;苔草叶片长宽比最大,芦苇最小;互花米草茎粗最大,苔草茎粗最小;互花米草单位面积生物量最大,苔草最小。通过Pearson相关性分析表明,绝大部分植物在适应环境的过程中,其功能性状之间具有较强的相关性。
Study of plant functional traits is important for studying ecosystem succession and responses of wetland ecosystems to environmental changes. In this study, six functional traits of dominant plants were measured in Yancheng coastal wetland, including plant density, plant height, leaf area index, leaf chlorophyll content, stem diameter and plant biomass per unit area. The results showed that there were large differences among functional traits of different plants. Among them, Suaeda glauca had the largest plantdensity, while Triarrhena sacchariflora had the smallest one. The highest plant was Phragmites australis, and the lowest one was S.glauca. The leaf area index of T.sacchariflora was the highest, while the index of Spartina alterniflora was similar to Imperata cylindrical, P.australis. The species having highest leaf chlorophyll content was S. alterniflora, while the species having the lowest one was I.cylindrica. For leaf length/width ratio, Carex rigescens was the largest, and P.australis was the smallest.The stem diameter of S.alterniflora was the largest, while that of C.rigescens was the smallest. The largest biomass per unit area is S.alterniflora, and C.rigescens had the smallest biomass per unit area.Pearson correlation analysis showed that there were strong correlations between most of plant functional traits during the adaptation to the environment.
